[foxy1]

hello

any ideas on the best way to remove blue marks on bath. i am not sure whether this is from the taps? it is a newish bath which has not been used.
I don't want to damage bath.

Our sink has some paint in it as well any recommendation on how to remove this? thank you very much!!

sounds like limescale, maybe limelight could remove it? check it's suitable for bath surface first.

you can just chip away the pain on the sink with a toothpick or somthing that isn't likely to scratch

If it's bluey-green then it could be copper oxide. This would be caused by slightly acidic water disolving copper pipes being precipitated out of the water by the alkaline in the soap. To get rid of it you just need something acidic - I find lemon juice works really well, just leave it on for a while.

If it is copperoxide then I hope none of you are blonde - it turned my hair green

ok great thank you will try that!
