WD-40 Specialist_® Silicone

I've randomly tried this stuff, aside from the obvious. I used it on my kitchen cabinets, sink, counter top, faucets, and garbage can. Makes it waterproof and keeps everything clean because nothing can stick to it. I used it on my tub surround, faucets, and on the calk. The water beads right off and both the walls and caulk stay clean from mildew because it blocks the water from sitting, and the faucets shine nicely. I have also used it on my ash tray. It works great for keeping the ashes from sticking to it. And none of the things I've used it on have a slimy sticky film on them, like other products. My next experiments will be a folding table I leave outside for plants, an mdf desk I have outside for my plants, and the plastic fan blades for outside. Great stuff.

I've used it on a ball joint that is wet most of the time, as well as on a sliding mechanism that has metal on metal. So far so good, and it's lasted longer between applications than I expected for a silicone product.

WD-40 Water-Resistant Silicone Lubricant works great on our slideouts on our trailer. We use it once a month.
