Thank you all for replies.
Any soft wash undertaken by us we have been using wfp with algoclear so far. Minor domestic roof cleans. Scrape and spray.
We haven't been using hypo for soft wash yet.
Never pushed it but we landed couple of jobs from our current clients recently and one of them is this hotel covered in krend ( sorry for the picture but was actually taken to show my partner where we are to stay for 3 days when its to be done):
Another 7 hotels of the owner are on the way.
I trust there is a better way (or kit) for the application than 12v 6lpm pump and brush. Its not sarcastic in any way.
Leaving what i have seen on youtube from US i looked at Softwash, Algoclear and Benz and couple of companies that i met in Amsterdam during the last show.
Benz are very informative and I am keen to go with their advise but ist always good to ask people that do the job daily.
