Hi, I've got some horrendous rust stains on flagstones, from old cast iron
pation furniture.
What's the best way of cleaning these? Can it be done? I've tried all
sorts of the usual things and nothing really seems to work ...
Thanks.
I've forwarded this to Cormaic to see if he has any ideas and/or time to
tell us!
There is a chemical that will remove rust stains, people use it on GRP boats.
Oxalic acid. It is toxic,
That's interesting. Perhaps rhubarb leaves will remove rust - they
contain oxalic acid.
