I have a glacier bay kitchen faucet model 8181/785-564p with pull-down-sprayer in a brushed aluminum finish. I can't seem to find anything that works to rub out the water spots that are everywhere on it. Any ideas?

Have you tried CLR or something like that? The other thing is if the aluminum is unprotected they may not be actual spots but etching that occurs when water and aluminum come together.

Fantastic, 409, and CRL will all make your chrome faucet like shiny new. Good luck, Tom

Plain old vinegar on a rag.
