Thanks

would oxalic work?
How can you see white hard water stains on white vinyl?
I would try a mild oxalic mix on it. Do a test spot first.
It shows up as a light brownish calcium looking buildup. Not really sure it’s hard water. The customer thinks it is and the sprinkler system hits those areas. They are on a well and this area is typically known for hard water. It could be a sulfur stain but the is no sulfur smell in the water that I could see.
I’ll try oxalic…
Phil try and get a before and after picture… I would be interested in seeing it.
no possibility of rust?
Don’t think so. Nothing metal nearby. This place was the first power wash job and or course it has to be a tough one. I never get the easy ones first. What would be the fun in that? lol
Cool, post some before and after pictures. Sounds like a good learning experience.
gotta be honest with you phil. you’ve been stringing us along for 2 weeks now. no pictures, no results, no answers… nothing!
i’m dying to know whats going on
Sorry guys I have been busy. I’m going back to that job next week. I’ll get em then.
Pics? hahaha:D It’s been a while, but if you can find the pictures laying around, it could help us all.
Sorry guys, No pics. I lost the job to another pressure washer. I often wonder if he was able to solve the issue. Kinda frustrating, but I was at a loss. Not as experienced as many of you here. Thanks for helping anyway.
sounds like rust from hard water in the sprinkler system
That is very likely. The house is on a well and as my house is, the water is very hard.
If it is, what would you use?
Oxalic should do the trick…mix 8-10 oz per gallon of water in a pump up…I have run into the same thing doing residentials on well water
Oxalic always helps me
