[Elezen]

Well i already tried to clean 3 key that is sticky and they just keep being sticky lol.... (tried to clean with alcohol and all) and then i saw somewhere i should probably lubricate the key .... is it safe to lubricate them?  https://www.canadiantire.ca/en/pdp/permatex-ultra-slick-extra-fine-graphite-lubricant-6g-0280805p.html#srp is this one a good lubricant for those cherry switches? or should i go with https://www.amazon.ca/Super-Lube-92003-Silicone-Lubricating/dp/B0081JE0OO/ref=sr_1_5?ie=UTF8&amp;qid=1543874757&amp;sr=8-5&amp;keywords=Silicone+Grease (wasd keyboard selling the same as this one for their keyboard i think) 
Thank for the help in advance guys

you should replace the faulty switch once for all, if you have the time.

 

it's not that hard. get a sodering iron that can do 350 degrees, some solder, flux and a desoldering pump. cherry switches comes only 2 contact points, desolder them and pull it out using brute force. installing is too easy to type it out.
