Review on Pumie Hdw12 Scouring Stick Heavy Duty by Lindsay Siebert

Today I tried pumice stone on my old antique clawfoot tub for the first time. The tub is still in very good condition and not discolored at all - except for a light yellow ring around the inside of the tub. There are actually two yellow rings, one slightly higher than the one below. These rings will NOT come off with detergent and it was so crazy! I tried the stick today following the instructions. One of the rings looks better, but the other one, which I wasn't paying that much attention to, is still there. The tub looks better, and maybe I'm asking too much, but I definitely want to get rid of those rings. I'll try again and hopefully make more progress. I'm giving this four stars because it worked, but not as well as I would like. Many Thanks.
