What's the best way to care for grommets?

I've always used silicone spray on them.
It lubes the metal parts, but isn't harsh on the rubber parts like some oils/solvents.

shardian:

Once the rubber starts breaking down there isn't much you can do. The good news is that if they are still working good, then under light home use they will last for quite a while.

Personally, it is worth every penny to go ahead and replace them. I got lucky and bought some @ $5 before Ponyboy liquidated his stock.

Ken Layton:

There are chemical cleaner/rejuvenator solutions that work well.

At MCM Electronics (www.mcmelectronics.com) they have stock # 20-230 Rawn brand Rubber Cleaner for just $4.99

That little bottle goes a long way and it restores elasticity to the rubber too.

shardian:

If the rubber is at the point it is starting to separate, I doubt any rejuvenator will help it. If it just has general thin cracking marks, then you might have a chance.

When I replaced mine, the grommets were broken apart about half the way around. You can't fix that kind of damage.

Fortunately, it's not cracked or broken.  It's more like the rubber is flaking or wearing down, sort of like what you'd see on a car belt after it's been used for awhile.  There's a powdery layer of worn rubber on the grommet and in the housing.

I believe I'll give the Rawn Rubber Cleaner a try as Ken suggested.  I've got four grommets to maintain, so it seems like a cost effective way to start out.

Thanks for all the responses.  I love this community.
