Hi,

Having previously had a few problems with some Romex resin soiling (my fault) on my Forest Pennant sandstone, I didn't seal the paving last summer.

Having cleaned all the winter soiling, I now seem to have some light rust staining across a number of the flags. It looks like it is from the iron within the stone. It is light staining but spread across a few large sections of the flags.

I can't seem to remove it with the lemon/distilled clear vinegar option and before I think about a oxalic acid, wondered whether anybody has tried the Lithofin option.

Any view on this product or further advice would be appreciated.

Many thanks as ever,

Damian
