Hi, I'd like to prepare a seaweed cleaning solution that I can do myself in my non-chemical warehouse. Last year I made a mixture by mixing 5 litres of water into 1 litre of 20% hypocrolite. Since the stone is absorbent, the hypo dries up on the stone, and after a few days it begins to bloom, I have to clean it again. Now there are 700 m2 of stone to be cleaned, what would you suggest.

Just pre wet it with plain water and clean it with PSRP XTreme Heavy Duty Tile & Grout Cleaner diluted 4:1 then rinse it with PSRP Ph Pink.  Then seal is with PSRP H2O Impregnator

Hii, Kev Martin, the customer wanted a quick clean-up. I diluted 15% hypochlorite fresh 1/5 in storage and mixed soap and prepared a solution. I did a 5-minute test in a small place. Moss saw it cleared in 5 minutes, so I didn't dry out the hypochrolite when I cleaned it. I applied a regional solution and rinsed it with plenty of water. I did a soft wash. The rain has been steady for two days. Moss stands a 500 m2 stone to be cleaned..

Sunshine!   Your profile says you are in London but this area is in Turkey!!!  Why bother asking if you know how to do it???. There are plenty of people on here who genuinely require help and I certainly don't have time to play games with you Chum!

I'm asking why? Now I'm telling you all about it....There are pressure washing and soft washing companies in Europe & America... These companies have facilities that produce cleaning materials, there is a sector... How fortunate that such a plartform has been established...Where you have problems, you ask and ask for answers...There are Soft wash training courses...Yes, I live in Turkey... A lot of my family have been UK citizens for years... My job is printing... The printing industry is ending as the world moves to digital books... I was unemployed... I decided to do this... No one does this cleaning work in Turkey... I wanted to be the first...Karcher bought gasoline pressure washing machines and many more machines...No doubt you need detergents to make cleaning easier...There are no companies to produce cleaning supplies because there is no industry in this business... People who do don't do things that work for me....I take substances like sodium hydrochloric acid, nitric acid from chemical plants and mix them with water to prepare solutions... I have been a member here for not finding the answers I am looking for in Turkey... I read your comments... I watch Youtube videos and read comments made...I'm taking notes.I've finished two books...I make solutions myself, do cleaning trials, shoot videos...In short, Turkey is behind everything... I'm not going to give up after I've invested so much...They wash cars with pressure washing machines in Turkey...I'm trying to clean me up... I need solutions to make my cleaning easier...I'm just waiting for one of you to comment on my question...
