The tenants at my daughter's rental property let the bathtub faucet
drip for a couple of years, building up a
rusty area about 12 inches in diameter beneath the faucet, except
directly under the drip where the build-up was washed away. I tried a
spray-on iron/rust remover, but it only helped around the edges. I
was able to scrape off a little portion using a screwdriver, but am
scared that I may damage the tub. Can anyone recommend a super-
strength remover? I vaguely remember something about oxalic acid as
being useful, but not sure.

TIA,

OxiClean usually a laundry soap contains oxalic acid.
It is sold at Home Depot.

Iron out can also be used.

Oxiclean does not contain oxalic acid. It is a percarbonate which
hydrolyzes when mixed with water to ultimately produce free oxygen.

Oxiclean is dehydrated Hydrogen Peroxide?

No. When water is added to Oxiclean hydrogen peroxide is released from
the percarbonate.
