HI everyone, here are some of the before and after pictures of my first Tile roof cleaning.

'had a good sauce mix but the run off was horrible, I will be incorporating some Ammonyx lo to the mix so far from what I have read it should help a lot.

I was using a 50/50 mix of sh and H20 with Dawn if you have a better mix for cement tile cleaning, please any sugestions are welcome, Thanks everybody....
