DuPont Multi-Use Lubricant with Teflon Fluoropolymer, 11 oz Aerosol Spray

I've found this to be a good bicycle chain lubricant. I can't seem to make up my mind between wet and dry lubricants. Dry lubricants like this are more useful for chain cleaning and seem to keep the chain cleaner longer. Wet lubricants tend to leave the chain quieter, but attract more dirt.

Dupont multi-use is considerably cheaper than the bicycle-specific brands, though I suspect it's the same product. If you're in the market for a dry lubricant I'd look no further.

The spray bottle is useful for spraying off grime between full cleanings.
