I just installed some new sliding closet doors, but unfortunately they're a bit squeaky/noisy when operating. They are "Reliabilt" doors from Lowes, the actual company that makes these is SGA. There's nothing in the instructions and nothing on their website about suggested maintenance/lubrication.

I'm not entirely sure what the rollers are made of, they're some kind of plastic or nylon rollers that fit in an extruded aluminum track.

roller mounted doors

What kind of lubricant can I use that won't break down the plastic, or gum it up over time from dust/etc?

Any dry silicon spray lube will be fine also. Do not use and petroleum based lubes or WD40. Wet type lubes attract dirt and dust and get very messy. Same advise goes for door hinges.

Ended up using "jig a loo" which is silicon-based (the box store I went to surprisingly didn't have a huge selection). Seems to have done the trick, hopefully stands the test of time. –  gregmac Mar 1 '11 at 15:21
    
Any time it starts to bind a bit, give it a shot!!! –  shirlock homes Mar 2 '11 at 23:14

It's been well over a year, no problems at all. A few days ago actually I gave them a quick spray but only because I had a squeak in a door (not these ones) and so went around and lubricated all the hinges and such. –  gregmac Jul 24 '12 at 0:21
    
Glad to hear you had good success with the silicon lube. It is the only product I will use on hinges, windows and locks. –  shirlock homes Jul 24 '12 at 10:50

A PTFE (aka Teflon®) spray such as this should do the trick. They're widely available, and in several brands so you should be able to find one easily.

The squeak comes mostly from the roller turning around its axle, so I spray a little in between them and spin the roller a few times to distribute it. Clean up any excess with a paper towel. I don't have problems with them getting clogged with dust (and I think I have more than my fair share of dust!).

Another option is powdered graphite, available at any home store in a little tube for about 2 bucks - a tiny bit squirted into the roller/axle area, if that is where the squeak is coming from. This works great for door hinges as well, and does not have the disadvantages of spray oils like WD40 (sticky, wears away quickly, etc).
