alright ive tried spraying them down like crazy, banging the keys, air hammer, etc. ive had three other people try to break them loose. is there any other secret?

im trying to bring down the rear a bit. they arent budging. they havent been adjusted in about three years. dont try to say they are cheap bc they probably cost more than just about everyones on this forum

and please all the annoying people stay out of this. im not an idiot
