Grease suitable for electronics

Recommended Posts

Years ago I bought some hardware that included a sample sachet of white silicone or lithium grease. That's since long been used up, but I have a need for some more and, for the life of me, I simply cannot find anyone who sells it. Most hardware shops haven't even heard of it, the local electronics shop (a Jaycar stockist) doesn't carry any, and I've rung a couple of the local electrical wholesalers with no luck. Does anyone know where I can get some?

 

In case you're interested, I need to to lubricate the keys of an old keyboard I stripped down and cleaned on the weekend. The board chow is gone and all the contacts work flawlessly but the keys are traveling a bit stiff. If you have another alternative then I'm open to hearing about it.

The white thermal paste that is used on CPUs etc is basically silicon grease with some thermally conductive filler added, so I would just use a dab of the cheap white silicon thermal paste.

Otherwise

Personally I wouldn't use any sort of "wet" lubricant as it is going to attract dust and grit like billyoh. Better off to use some sort of dry spray on lube like

Thanks for the hints, guys. Your comments reminded me of a lube we use down at the fire station on cam-lock hose fittings. It comes in a dry stick and I'm fairly certain it's got a silicone base. This is the stuff at Super Cheap Auto.

 

I'll double-check it contains silicone before I try it, otherwise I'll look up your other suggestions. I didn't even think of an auto-parts store at first so I appreciate the pointers. :D

Well, I took the advice of the general consensus and bought a can of silicone spray lubricant (same stuff aliali suggested). I took all the keys off and gave them a light spray, then put the keys back on.

 

Now I'm sorry I did it. :(

 

I don't know why you guys think silicone spray is so great, but the keys on my 'board are stickier than ever. When I push down on some of them I can actually feel the posts grating on the side of the holes. It's positively awful. The keys traveled a lot smoother even without any lubricant.

 

Maybe I got a dud tin? It wasn't "dry" at all...very oily when I sprayed it on, and I had to ensure I wiped the tops of the keys before I put them back on (this was after allowing it to dry for a while, which it never completely did anyway). Further, because the posts on the keys are hollow that means the oily substance pooled in there, and as soon as I tipped one over to push it into the 'board the oil ran out onto the membrane underneath. So, I hope the oil isn't attacking the membrane now.

 

If the grating doesn't settle down I'll have to strip the board back (again!) and clean it all out (again!). Any other suggestions?
