Did you use surfactant on those rocks? If so, be sure to rinse really well. The surfactant can creep to the surface and leave tiny white lines everywhere.
I post treated the brownish rocks by the way with my downstream chemical. The ones that I was not happy with. So we have yet to see how everything has turned out. After chemical and gas I netted about 50 bucks for about four hours doing those rocks.
UPDATE: No sooner than I posted this I got a hold of the client and they said the rocks look great. They said thank you. So know I know not to panic and let the chemical and the sun do the work. Post treat pre treat post treat etc. etc. Looking forward to getting my 12V built so I can cut those four hours to about 20 minutes. @TexasPressureWashing
Good to hear. In the future I would be cautious about over promising.
As suggested above always under promise and over deliver. Good luck! Merry Christmas!
Ditch the j rod on this job and put a bit more pressure to it. Soft washing some things isn’t always the answer.
Yes I did used it in the sprayer. I think I saw some of that what you are talking about and that helps in the future.
