IronX Remover safe on Seal Coated driveway?

It should not affect your driveway but because companies can not test their product with every single material on the market you should apply it intentionally to a small area a few times whereit won't be seen and be sure that it does not affect your sealant in a way you would not like. I highly doubt there will be any affect

never had any problems when used on my sealled driveway, maybe 2 weeks after it was sealed, but then again, when it touched the driveway is was diluted with water...

on a side note, TRIX does seem have a bleaching effect when it touches clothing.
