Hi,
I'm replacing an enamel bathtub waste drain and have removed the old plughole, but it is quite corroded/rusty where the old black rubber washer was seated below the chrome plughole. What is the best way to clean this up before fitting a new waste? Scrape with screwdriver? WD40? Some sort of commercial rust remover? If so what type? Any advice greatly appreciated.

Hi flilley,
Do not use any form of chemical cleaner, this will etch the enamel surface and ruin it. Suggest you try a scouring powder cleaner but you may find the rust has deeply stained the enamel.
Regards S

Many thanks I'll give it a go...
