9 Tips to clean the Arduino Membrane Keypad

How to clean a membrane keypad?

Now we will give you some very easy tricks to clean your membrane Arduino membrane keypad even if it is dirty, making it as easy as possible to clean it and preventing dust or dirt from damaging our precious membrane keypad.

Although it is known by all, we will emphasize that to clean your membrane keypad we will do it with the membrane keypad disconnected to avoid possible problems of short circuits or circuit breakdowns that spoil the membrane keypad.

How to do general cleaning on an Arduino membrane keypad

We will perform this cleaning once a month or at the latest every 2 months to avoid too much accumulation of dirt.

The materials that we will use in this cleaning are easy to find since most of us have them at home. These materials are:

Arduino membrane keypad Kitchen paper.

Membrane keypad disassembly kit (normally included in all Arduino membrane keypad packs common to remove the membrane keypad keys) or, failing that, a flat and fine-tipped screwdriver.

• A glass of distilled water preferably or, failing that, warm water.
• A camera (the mobile camera is worth it)
• Patience as it is a process that takes time.

All the materials mentioned above will be common with the membrane keypad disconnected and in a well-lit place to be able to observe well if there are traces of dirt, dust, or stains on our precious membrane keypad. Next, I will

list the steps to follow.

1. use the kit to disassemble the membrane keypad that usually comes in the box or, failing that, the flat and fine-tipped screwdriver and we will remove each piece of the Arduino membrane keypad.
2. take a glass or a bowl of distilled water if we have it or if we do not have warm water.
3. After removing all the keys, they insert into the container that we have previously taken.
4. it over the surface of the membrane keypad without the pieces.
5. cut another piece of kitchen paper and we will pass it through where we just passed the previously moistened paper.
6. Once the membrane keypad is dry, we will proceed to dry the keys that we have in the container with water piece by piece.
7. When all the pieces are dry and we check that they are completely clean, we will proceed to place each piece in the place that corresponds to them without forcing the pieces and using the help of the photo taken in the first step.
8. With the parts fully placed, we will plug the Arduino membrane keypad into the device and check that all the parts work.
9. If we follow all the steps calmly and without haste, nothing should happen when we have the membrane keypad plugged in and all the keys should work correctly.

How to do routine or weekly cleaning on a membrane keypad

It is good to get common to this cleaning once a week so as not to accumulate large amounts of dirt. For this cleaning. And the failing that, a small air gun, some swabs that we usually use to remove wax from the ears.

Also, hot water or distilled water to avoid any electronic problem. And if we have a small handheld vacuum cleaner, this will allow us to facilitate and speed up the cleaning of our membrane keypad.

Without disassembling the Arduino membrane keypad, we will pass the stick through each of the keys removing the dust, once we verify that we have removed all the dust we will proceed to the next step.

We will prepare a container with the distilled water

 or, failing that, the warm water and moisten a little kitchen paper. And repeat the same process that we did with the cotton buds, this will allow us to remove the largest dirt that sticks to the keys.

We will take a new swab again and moisten it in the water previously prepared in the container, the swabs will allow us to access the corners that we previously missed with the paper.

The final step is needs dry kitchen paper

We are almost done, we will proceed to the final steps. This time we will need dry kitchen paper. And we will pass it again where we pass the swabs to dry all the possible water that has remains on the Arduino membrane keypad.

This step is optional and we will only do it if we have a small handheld vacuum cleaner, or, failing that, a small air pressure gun, since once the previous step is completed we will go over the vacuum cleaner to remove all of them.

How to do quick or emergency cleaning

This cleaning is finis when something accidentally spills on the membrane keypad and we need to remove that dirt immediately to avoid possible breakdowns.

If the product spilled over it is a liquid, we will follow the following steps:

• Immediately disconnect the membrane keypad to avoid a short circuit.
• remove all the spilled liquid.
• take kitchen paper to absorb the remaining liquid that could remain on the membrane keypad.
• moisten kitchen paper to clean the entire affected part and thus avoid stains.
• pass dry kitchen paper again to finish absorbing all the moisture that remains.
• Finally, we leave you a video with a way to clean the Arduino membrane keypad

Is the warranty lost if we disassemble the membrane keypad and clean it?

If you follow all the steps correctly, you should not have problems with the warranty since today. And all membrane keypads usually come with a spare parts kit. So that within the purchase itself they give us the option to disassemble our membrane keypad.

Conclusion

At membrane keypad. top we do not support fraud. And membrane keypad modifications, because if they go wrong, the warranty will not be denied. Furthermore, we do encourage you to have the membrane keypad clean.

And following the steps shown above, you will not have any problem in that the warranty covers your Arduino membrane keypad in case of external failures when changing parts or cleaning it.
