Then let your keyboard air dry completely before trying anything else. This usually takes about 2-3 days.
You can also use a disposable cleaning wipe to get this job done.
You can also try using the jelly material with the keys still on. But you’ll get a more efficient clean if you remove the keycaps. Be careful not to use a compound that is too sticky, as this could result in residue being transferred to your keyboard that negates the whole point of cleaning it in the first place. You should be able to purchase sticky compound at any office supply store.
Try to keep the keycaps sorted so that they are easy to reapply. You might consider keeping all of the keycaps from the right side sorted together and all the keycaps from the left side sorted together.
You can also submerge the keycaps in a bowl containing a solution of warm water and denture cleaning tablets. Let the keycaps soak and then wipe them off. Let the keycaps dry completely before attempting to reattach them to your mechanical keyboard. This could take 1-2 days.
You could dump it into the trash, but then you risk all of the debris flying around and settling elsewhere in your home. You can also spray some compressed canned air on the keyboard while it’s upside down to get rid of some of the extra grime.
Be sure to let the remnants of the rubbing alcohol dry completely before you put your mechanical keyboard back together and plug it back in. This could cause your keyboard to short out and ruin it.
Make sure you position the keycaps back in the correct place – you may want to consult a diagram of a qwerty keyboard before beginning.
You can usually find cans of compressed air at office supply stores for less than $10. Spray your mechanical keyboard with the compressed air once every few days to keep it nice and clean.
This will help your keyboard stay cleaner for longer since you are actually eliminating the dust, rather than just blowing it around.
Follow any cleaning instructions in the user’s manual and consider contacting the manufacturer for a replacement if necessary.
