It seemed to activate again also when it rained. The only down fall was a the box came damaged and it split in the box but the seller sent another bottle in good faith - thank you will always use this product if needed again. Perfect.

Ok, so it does get rid of green mould, however the black mould seems to be more of an issue and can still be seen. We normally pressure wash the flags every year and although this is time consuming, it does get rid of almost everything and does leave the flags shinny and like new. Having seen other users photographs (of Pro Kleen) which did suggest that this cleaning can all be closely achieved with spraying Pro-Clean Patio Cleaner and just leaving it for a few days, we were all excited to use this product. The end result for us was a mixed bag, nearly all the green mould has disappeared but the black mould can still be seen everywhere and thus we may end up pressure washing certain areas to clean it fully.

This product is fab! Really good at removing dirt build up. I sometimes use it twice on stubborn areas but saves us hours with the jet wash!

Used it not one of the best ones, just as easy to uses a pressure washer
