This may seem a strange question, but here goes. We have a real oak floor in
the bathroom, waxed regularly. Sadly my ill Father in Law has been staying
recently and we have just noticed a nasty black stain on the wood has
developed under the bath mat!
Clearly a reaction of urine and the wood/wax polish. I have tried washing it
off with no success.
Any suggestions of how to clean this off. The last resort will be to sand it
but I would prefer not to if possible.
Thanks in advance. John
