Leather Care

 Leather care.

In humid weather in Malaysia, it common to encounter fugues on leather surface.

Issue with fungus growth on certain leather surface is observe so far. 

Way to treat and minimize the fugues issue on hand.


Can see patches fungus appear on surface .Looks like coming from the pore of the leather material.

This is common due to local environment which humidity is high all year round.










Overall view of a tote bag handle with growth on it surface.
The tote was hang near window.

This issue keep surface out from time to time and depend on leather material type. Not all leather type have fungus issue. looks moldy and light green.








Side of tote bag with moldy growth on the surface and patchy in location.









Close up view.










Try use dry cloth and rub and dust off. If cannot remove try use wet cloth to slowly rub it off. Or try use sponge with water and rub surface.

At one time try use plastic brush, but this did not wok well.

After cleaning and let dry and apply olive oil on surface. Please check is olive oil is suitable is to try out on a small area which is not noticeable before apply to whole leather surface. As certain leather have properties and characteristic that the surface colour might not be suitable.


Found some web site and video on this issue ( have not try some method as lack some items locally):-

Check this out and share your feedback. 

Tips :- ALWAYS test with any new chemical on small spot or not so noticeable area if you are not certain it will change or impact the leather surface.

Update 10th Jan 2021.

So far after rubbing olive oil to the handle of tote bag, and leaving the tote bag at the same location. After several weeks did not see fungus on handle so far.

 Hopefully the olive oil manage to penetrate into the leather pore and minimize fungus growth.

Will still monitor and check the leather surface from time to time.  

Update 12th Feb 2021.

So far have been monitor status on leather, it looks promising result after use cloth and wet slightly and use to rub off the fungus with good result.


Update 26th Feb 2021.

Storage in the same location, it looks effective to minimize fungus on leather surface. Not sure because of dryer weather during month of Feb before Chinese New Year. Will continue monitor status.


Update 22nd March 2021.

Status it is good condition so far. Keep finger cross.


Update 10th Oct 2021

The fungus have return.. try out use water with vinegar to clean.

5. Fine sugar 30gm. ("food" for yeast)

6. Baking powder 5 gm.

** This process need your kneading skill and for how long to do it right??

** Do take note in certain country the temperature environment play an important role in making bun, like water temperature, proofing location, local temperature. So do adjust base on your location needs.

10. How to Make the Mantou Dough / 怎样发馒头的面        •9 Dec 2014
by Cooking With May Lynn (2:07 minutes)
 
This is my recipe for mantou dough, but it is very versatile and can be used for everything - mantou, baozi skin, and other various types of buns with both meat and bean paste fillings. It is easy to make and I recommend it for everyone!!




Overall view on some ingredients and equipment.










Top left is shortening oil, top right is extra flour for spread on table top surface or spread bowl surface when proofing dough.

Middle is baking powder

Bottom left pau/pao flour 500 gm and bottom right is yeast 11 gm.






With normal room temperature water is mix with sugar and then place yeast into water.

 It take time for the fermentation process, initially the yeast float but will sink later.








Can see the yeast start to sink down slowly to bottom.








After about 10 minutes you can see a lot of bubble on surface of water. This is a good sign the yeast is eating it sugar food.

This part of fermentation process is working fine, this indicate it is working and ready for use to make Chinese bun dough.






Notice the bubble foam layer on top of the water, this is a good indication of a good yeast.
* if you do not see this action STOP and check before proceed to next step.

Next pour this mixture into the pau flour mix and stir well the ingredient.






With bowl with baking powder and pau flour is mix properly. Next pour mixture from measuring cup which have water, sugar and yeast.

This is the starting process of kneading the pau dough.

Typically need to knead the dough for about 10 to 15 minutes. This depend on the texture as the dough is soft and springy.

There is various way to knead the dough, I prefer to use the manual hand method. You can feel the dough texture as you move forward.

Kneading technique is, use the heel of your palm, push into dough and keep turning the dough over. Turn and squash dough. Let your finger tell you the state of dough. 





If you break the dough into half you can see a lot of air pocket, it indicate the kneading process is working fine. Continue kneading for about 15 minutes.

Next is to spread flour on the bowl and allow to proofing for about 1.5 hour to 2 hour.

This also depend on the room temperature.

Inside of the dough has a rich cellular structure, also abundant honey combs inside indicate fermentation is complete. 






Initial size of the pau/pao dough and cover it with plastic wrap or cloth  or any cover that fit.


TIPS:- If after several hour the dough size is still the same size. 

It is very high probability the yeast is "bad".

 Encounter twice this situation, as the yeast was mix all together with other ingredient.

This is one learning point to check yeast status before pour into flour mixture.



After about 2 hour later you can see the size of the dough have increased in size.

Next step is to cut dough into about bite size of 50 gm to 70 gm each.








This bun have filling added inside, weigh about 80 gm. dough skin about 70 gm and filling about 10 gm.

Note when have filling it recommend to add a bit of cooking oil with filling.
If you rub oil on the inside of skin surface before place the filling then the pau will have a air cavity inside.

It recommend the filling portion, if too small quantity there will be more air space inside. This can result the pau shape is flatten.






It is recommend to let the pau to "rest" a for about 10 minutes before steaming it.

In the meantime you can set up steamer to get ready and correct temperature.

Tips:- Open lid after 2 minutes. 

*Don't open lid right after turning off fire, sudden changes of temperature will result in buns collapse.

- Steam from cold water. 15-20 min. if the fermentation is at the right level, you can steam long time without worrying about collapsing surface. 
- once time is up, turn heat off, open the lid just a little bit, wait for a few minutes before taking the buns out.


= = = = = = = = = = = =  Try add sweet potato to pau dough = = = = = = = 

First cut sweet potato and steam it for about 15 minutes.

To check is the sweet potato is cook or not is use a fork or chop stick and pork it, if it ready you can pierce it through.






Smash the sweet potato with a fork. It better to slowly make it into smooth paste.











Mix baking powder (5 gm), shortening oil (20 gm), pau flour (300 gm), add sweet potato (120 gm).

Knead the mixture a bit before adding yeast, water, sugar mixture into bowl.







Note:- Note this proportion is too watery mixture, as the sweet potato is already soft and contain water content. Should have adjusted the water level to about 100 ml and slowly adjust into dough.

pour from measuring cup ,water 250 ml, yeast ( 5gm), fine sugar (30 gm). 


Initially the dough is allow to proof, see the size changes after 2 hours.










Notice the dough have rises up and ready to cut to bite size before steaming.

It is too soft and wet, hence need to add more pao/pau flour. It was because have added too much pre cook sweet potato in this mixture.







After finish steaming pau/pao for about 15 to 20 minutes minutes.

* If steamer is start from cold, it best to steam the pau/pao for about 20 minutes.








This is the final product, can see the inside texture.










Update on 30th Dec 2020

Another mixture combination and proportion in this pao/pau project .

1. Pau flour 480gm. 

2. Baking powder 10gm

3.Dry Yeast 10gm. and 250 ml of cold water

4. Shortening 20 gm

5. Pre cooked Sweet Potato 120 gm (with 30gm sugar added).

Found this result in the dough is soft texture and make it challenging to wrap filling. As the texture is too soft and make difficult to wrap item inside.

Final result the pau/pao skin is rough due to sweet potato is not smooth. It edible and can see air bubble when peel. 


End result, notice the shape changes after steaming pau/pao.
As the dough was soft and not so easy to apply the pattern.
Partly when rest the pau/pao before steam it still raising a bit.







Open a pao/pau with filling inside.

Can see the texture is a bit rough on surface but when eat it taste ok.

Comment very useful tips, notice the skin is very thin and did not shrink the edge of the dough.


= = = = = = = = = = = = = = = = = 

These project have provide some learning process as it is a skill base..learning new skill have to relief from stress from pandemic..as we move forward to year 2021. 

           Welcome and Happy New Year 2021  greeting.

Update 10th Jan 2021

  Was very determine to try out making Chinese steam bun and want to learn how to improve and make more consistent Chinese steam pau. 

As the result of each batches there are some variation in the outcome as also introduce other method and ingredient and etc.

8th Jan 2021 (Friday, morning).  prepare the following ingredient for project.

1. Pau flour 530gm.

2. Dry Yeast 10gm

3. Fine sugar 30gm

4. Shortener 20gm

5. Water ,cold 250ml.

6. Baking powder 15gm

7. Red bean paste 450gm


Start and leave dough to rest. 

With all ingredient mix inside bowl, at first it look "messy" as it take time to slowly mix them until it become dough shape.

Initially the pau flour mix with baking powder and shortening and stir well on mixture. 

In this project the yeast is mix to water with sugar and allow to rest for about 10 minutes. This was added to the above mixture on bowl.







When dough is ready it is let to rest for proofing.

Initially the dough is this size, over time it should increase in size.





After about 1.5 hour proofing dough, should notice the dough have increase in size.

Compare with other "people" dough notice the surface is rough. 










Weigh dough of about 40 gm .
Add filling (red bean) and the approx weigh is about 40gm.
Notice the dough was roll and flatten.
It is not recommend to flatten the dough skin too much, it could result in the skin spread too thin and compact. It could cause tougher skin and affect the taste after steaming.
These are some shape try out. Still need practice in shaping the dough.
After 15 minutes of steaming buns.
This is one of the bun with red bean filling.
You notice if the skin is too thin the result is the base is harder and stiff.
Not so good outcome.

Non leather project #13 (Battery holder, led dimmer)

 Non leather project #13 (Battery holder, led dimmer)

This project is to fabricate a battery (12 Volt) holder and mount a led dimmer control module with foot on/off switch.

Main objective was to make a simple belt to strap a portable 12 volt battery on a board.


Cut a small board to be use as base for battery holder.

Two small strip of leather is added, to provide a spacing lift-up to support battery base cover.

Two webbing straps is to add as fix point for the elastic strap to provide support with button.






Place a battery module to check position to add webbing strap, as position and webbing length is important to secure a heavy battery module.

Base on this battery size and length the webbing strap is decided . The webbing end should be able to wrap the battery body.
Once the position is confirm on  webbing strap. Use a stapler gun machine attach webbing strap to board


Initial stapler to set and hold it in position, apply glue in between base a webbing strap.

Use glue to hold a small leather strap, it is to lay over on top the webbing strap.
This is give a better support and act a stress relief to support battery module.

Apply glue to both the small leather strip and board.
Use a lighter to heat the edge of both cut webbing strap and elastic strap.
This is one method to minimize the cut edge from fraying.

Important to ensure the lighter flame is not too high, a smaller flame is easier to control amount of heat to melt the plastic material. Another way to control heat to material is to move your lighter try not stay long at one position. 
Punch hole on webbing strap and place VT2 button.

Use correct punch hole size for VT2 button.
This is to show both elastic strap.

Left item is the bottom view.

Right item is the top view, note the white dot mark to punch hole for VT2 button.
See the spacing between the webbing strap (VT2 button) and elastic strap dot marking.

This how the webbing strap and elastic strap are mounted.
Do take note the elastic strap have added small leather to better support when stapler it to base.

This is to display how the battery is mounted. The leather flap is to make it easier to button up and un button.

Mount a dimmer module next to battery.



Done project.

Non Leather repair #26 (Plastic bag Sealer 20 cm) -ノンレザーリペア #26(ポリ袋シーラー20cm)

 Non Leather repair #26 (Plastic bag Sealer 20 cm)

ノンレザーリペア #26(ポリ袋シーラー20cm)

Receive a defective (broken heater element) plastic bag sealer 20 cm for repair. 欠陥のある(ヒーターエレメントが破損した)ポリ袋シーラー 20 cm を修理のために受け取ります。


Note the original heater element was one end use screw to tighten while the other end it was wrap around to metal post. The metal post was attached with soldering for connection to element.

The new heater element part was with both end with ring lug terminated hence it require a different way to repair this plastic sealer.

* Note :- this heater failure could be due the timer setting was set too high. Other possible cause or factor could be the thermal insulator surface are dirty. Hence result in user have to turn the timer setting higher. Notice the asbestos insulator block have black mark from the heater element.

Hence user need to be extra careful and ensure thermal surface are clean after use.



This is the label attached to plastic sealer specification 220 Volt to 240 Volt AC.

Brand name is Yong Teli. (country of origin China)








Overall view of plastic sealer, with some of the heater being removed.

New heater element part have both end terminated with ring lug. This pose a slight challenge in this repair as the original heater with one end was soldered to metal post.
The metal terminal post need to drill a small hole to allow the ring lug to be mounted to this metal post.




Top is asbestos block (pink colour) - it is to support the heater element and ensure even surface for heater to spread heat evenly.

Middle is new heater element - it is heat up evenly along it length.

Bottom is the thermal insulator sheet - it is to prevent plastic material stick to heater and allow even heat distribution.



Inside view with bottom cover removed.

On the left is the timer circuit, next on the right is the transformer 






Inside view with bottom cover removed.

On the right side is the micro switch and transformer and metal post (a white wire connection, near to spring)






This is to show the heater element ring lug need to connect to metal post.

The "L" metal post have solder material, it first to remove this excess solder. Next drill a 3 mm hole for connecting the element ring lug with screw and nut with ring spring.




A close up view of the "L" metal post.
The two holes on "L" shape metal post is to mount it on plastic sealer. A new 3 mm hole was drilled to "L" metal post so as to accept a 3 mm screw and nut with spring washer. 「L」メタルポストの拡大図。
「L」字型の金属ポストの 2 つの穴は、プラスチック シーラーに取り付けるためのものです。 スプリングワッシャー付きの 3 mm ネジとナットを受け入れるために、「L」金属ポストに新しい 3 mm の穴を開けました。

Note:-  It is real challenge now the metal "L" shape post have one end of the heater ring lug attached. Have to take extra care when remount the heater element as the space quite restricted and to mount screw on the mounting point. 注:- 金属製の「L」字型ポストにヒーター リング ラグの一端が取り付けられているのは、非常に困難です。 スペースが非常に限られているため、ヒーターエレメントを再取り付けするときや、取り付けポイントにネジを取り付けるときは特に注意する必要があります。



Use a multimeter to confirm heater element before assembly. 組み立て前にマルチメーターを使用してヒーターエレメントを確認してください。









Close up view of the connection for the "L" shape metal post to heater element ring lug. 「L」字型金属ポストとヒーター エレメント リング ラグの接続の拡大図。

Before repair the metal post need to remove excess solder from surface. Drill a 3 mm hole and use nut and screw with spring washer to make connection to metal post with element. 修理する前に、金属ポストの表面から余分なはんだを除去する必要があります。 ドリルで 3 mm の穴を開け、スプリングワッシャー付きのナットとネジを使用して、エレメント付き金属ポストに接続します。







Final inspection after install new element is verify the heater is working. Set the timer to the minimum setting, Press the top movable bar and can hear the micro-switch clicking sound. Can feel slight heat and feel warm to touch with finger on thermal insulating surface. 新しいエレメントを取り付けた後の最終検査では、ヒーターが動作していることを確認します。 タイマーを最小設定に設定し、上部の可動バーを押すと、マイクロスイッチのカチッという音が聞こえます。 断熱面に指で触れるとわずかに熱を感じ、温かく感じます。

Try out with plastic bag and it can seal as per normal usage. ビニール袋で試してみると、通常の使用法どおりに密封できます。

This conclude repair work is done. これにて修理作業は終了となります。
