Product FAQs

Q: We had our conservatory roof replaced with a solid roof that is higher than the original. We have bare brick in our conservatory but there are marks on the brickwork from the old roof and some light paint/adhesive marks. Would brick acid be ok to use and is it likely to remove the marks?

Sharon Young

A: You could try the brick acid, as long as it is rinsed off 10 mins after application, it will not damage the bricks or the pointing.

Response from Nigel

Q: Do you recommed this product to remove moss from a tarmacadem tennis court, if so would it remove the colour { green and red ]


A: The Brick Acid Cleaner could harm the Tarmac. We would recommend one of our Green Clear products to get rid of Green Growth as it will cause no harm or discolouration to the surface.

Response from Ricky

Q: Will this remove litchen moss and black spots from deeply engrained very old Cotswold (4O years+)stone as we’ve tried your moss and patio cleaners with limited success, if we seal after

MrsLesley Tomlinson

A: This product would not be recommended for patio cleaning, it could remove colour from the paving slabs and weaken the pointing if left on too long. Used as per our 'how to' video Patio Clean Xtreme will remove the patio black spot, but it might need a couple of applications if the contamination is severe. Hope that helps, Nigel@Smartseal
