Is within a safe chemical or product I can use to sterilize or clean the keyboard on my laptop?

Rubbing alcohol on a cloth with the machine turned off, don't apply much that it runs under the keys.

Stroke the keys, the alcohol volition remove the dried human oils. Test a small corner of you screen before do the whole thing. use a butter knife around the cloth to get the edges and cracks clean.

Nice around rubbing alcohol, it dries swiftly. Removes oils. So rotate the textile to a young clean space often, or else you meet transfer the oils rearmost to the surface your cleaning.

Screen the whole case too, then once your done, remove all the stickers and their glue with concentrated red cleaner, wipe the whole machine down (not the screen), it's somewhat oily, but dries and smells great. Makes the case shine!!
