I've just found that Steradent (or Superdrug equivalent) dissolved in my husband's urine bottle has worked on a slightly murky area that hadn't been improved by a bleach solution and was beyond the reach of a brush. I wonder what else (apart, obviously, from his false teeth) these tablets will clean?
Hi Celia,
I think they will remove the brown stain from inside a teapot.
I expect there will be lots of other uses.
best wishes
Wendy
