Cleaning the touchpad on a laptop?

Question

laptops

Remind the guys, please, when I saw such a tool that you spray from a cylinder on some kind of electronics spare part, for example, on a button, the tool foams like hydrogen peroxide and any dirt that sticks falls off. Wipe with a cloth and it's like new.
Filled a piece of laptop a bit blue. Spacebar and one button on the wheelbarrow. Cleaned the gap, all the rules. Touch - do not crawl. I want to puff.
