I have just spent the afternoon digging out my downstairs loo. It has been used for storage for about 6 months and the pushchair tyres have stained the floor blue
.
The tyres are black rubber - not sure if that makes a difference.
I've washed the floor with bleach. Then sprayed some flash on the stain and re washed and it hasn't touched it.
Does anyone have any good ideas?
It is the marble itself rather than the grout that has stained.
TIA
