Help me remove these bath marks please!

[trulyconfuseddotcom]

Hello - we have these weird marks on our acrylic bath and I'd love to get rid of them. They've occurred gradually over the last 2 years, and I suspect the colour may have come from me regularly dyeing my hair auburn (I've stopped now) but I'm not sure what the colour has adhered to to create these stubborn marks. Any ideas on how to remove them would be much appreciated! Thanks.

Try a magic sponge - they seem to get most stains out and dirt cheap!

Pink stuff the one in the tub.

Try Cif and a scrub daddy sponge

I'd try a bit of pink stuff. I've also successfully got a hair dye mark off a bath once by rubbing it with toothpaste.

Thanks everyone - I've ordered some Pink Stuff, will report back! 🤞🏻

Damn, tried the Pink Stuff but no joy. Anyone else got any ideas? I think there are companies who come and 'doctor' baths, but would prefer to get these sodding marks off myself if I can.

Bar keepers friend might work.

A friend of mine recommended neat bleach on hair dye when I got it on the surround on my sink. I put it on and wiped it off quite quickly and it worked but the dye was quite recent.

Nail varnish remover sparingly

Hate to tell you this, but I did that to my acrylic bath.
Tried everything.
The marks seemed to have sunk into the surface of the bath.
Only cure:
New bath.

But, there may be something I didn't try, so I'd give any suggestion a go.
