Cleaning sandstone, presoak recommendations, before pressure washing
G'day all
I need recommendation/s for solutions to soak mould etc on sandstone, prior to pressure washing.
This client has the dirtiest pavers I have seen around a pool/garden area, and I don't want to spend to much time and effort with a water pressure machine hacking at the surface. Sandstone can be soft.
I haven't had prior need for pre-wash solutions, so I need recommendations.
There are a myriad of products on the market. I just don't know which ones to trust.
Any ideas?
Thanks.
G

I have some stuff called Oxy Klenza given to me by a mate who's a stonemason, works well. I use it for removing mould off brickwork, but it's safe for use on sandstone.
