Cleaning your keyboard

Cleaning your keyboard
If you want to clean your keyboard but you don't know how to remove the key caps,
you will need a plastic card.

You just need to insert the plastic card into the gaps next to the key caps and remove them,
slightly exerting a force on the key caps.

They will pop off like a bottle cork
Just make sure to take a photo of your keyboard before removing the keycaps
in order to put the keycaps back on the right way.

Use a brush and a vacuum cleaner to dust off the retainers.
Finish off cleaning with a cotton buds dipped in alcohol and your keyboard will shine like a brand new one.

If you need to put a mobile phone into your bag, put your mobile phone in a case, having fliped it over to avoid scratches.

Now the screen of your mobile phone will not get scratched.
When you need to seal a plastic bag, take a knife and heat it up above the oven burner
Then cut the plastic bag with your knife and you will seal the end of the bag.
If you do it carefully, it will even be waterproof.
