Treatment for rust on bath

[ohwell02]

It is a bit rusty on bit of bath rim adjoining the wall ( so on the grout sticking the bath to the wall) What is the best way to deal with this apart from covering with metallic paint?

Can you post a photo? If you want to fix it properly you'd need to remove the grout so you can get at the rust on the bath and treat it. You can buy rust remover from Halfords. Then paint the cleaned area to stop it from rusting again.

Do you know why it has gone rusty? Is it because grout has been used to seal the bath instead of silicone? Grout is not flexible so any movement of the bath is likely to break the seal meaning water can get in.

new bath.

Sorry it is silicone not grout. My mistake. It seems to be a mixture of rust and mould. I had a go with a mixture of bleach and water and it has worked to some extent. I agree the bath is not exactly new.

sorry for curt answer, but I have seen rust on old baths where the enamel has been damaged, and you don't have much chance of a permanent cure unless you can keep the bath away from water (ha!).

If you want to repair it you will have to expose all the damaged area until you can see sound enamel all round it, cutting away tiles, grout and silicone, abrade away the actual rust; apply a chemical rust killer (I recommend Kurust paste for that) followed by a metal preservative primer and gloss coat. It will benefit from several dry days to harden.

Before the days of Zintect, motorists used to spend millions of pounds a year trying to cover up and cure rust on their cars, with only temporary results.
