We recently purchased a pressure washer and pressure washed our driveway for the first time since the house was built (almost 10 years ago). I noticed there were rust stains around the driveway in certain spots, more than likely from an old golf cart my brother had that was pretty rusted underneath. My question is what is the best product to use to remove these rust stains? Thanks for any help.

Quite often those stains are not rust but battery acid. Muratic acid will clean it up if it is. Don't know if it will work on actual rust stains or not.

Actual rust stains can be easily cleaned up with calcium/lime/rust removers available at many home building centers, etc. ("CLR"). If it is indeed battery acid stains, I have been in the concrete trades all my life and am still trying to rid my two year old driveway of what I assume are just that! Good luck! (Do NOT use Muriatic acid on any type of "rust" stain on concrete....it will make it worse! Good luck!
