Brightening/Whitening Porcelain Bathtub
My bathtub is original to the house...60 yrs old.
Does anyone have recommendations on how to brighten and whiten it? There are some dingy spots from use and age.
The porcelain is not damaged or chipped...it's in overall excellent condition. And, it's clean. This is not a question on how to clean up soap scum or general bathtub crud. I don't have that. It's just dingy.
I haven't tried anything past soap and elbow grease. Does anyone have any experience in this?
