What size leg tank did you get?
I don’t actually have access to any super soft water in my living conditions at the moment, unless I traveled somewhere to fill it up, so I may just have to find some way to filter onsite, obviously not the most ideal.
Do you know of any methods to get hard water spots off, with a soft pad?
The hard water is just along the soffits and gutter, and an overhang, so I figure if there is a way to just buff them out with an extension pole, that would be ideal.
Vinegar, or dish soap, or any of the like, I have an extension pole with several pads, and scrub brushes, I think that may be easier than trying to filter the water.
All painted black aluminum soffits, guttering, fascia
Usually hard water spots just wipe right off if they`re only a couple days old. Just dont wipe it off with your rag/pad dipped in hard water lol. I wouldnt use soap or anything else unless you plan to give it a rinse with your PW when your done (with soft water of course). If you have a WFP that would be the best way to touch it all up if its not a huge area.
For a (very) short while I was offering a pure water rinse on windows after every housewash. My wife would follow along with my portable box 12v and rinse the windows with a fiver of DI water.
Eh, PITA dragging that 40# of water around a house, we have lots of hills here. Now people either don’t care about the smeary windows or they want a full blown window clean afterward.
WFP & pure water system are great tools to have. So is having a buffer tank.
FYI: very, very few RO/DI systems can put out enough volume to feed even a small pressure washer effectively without starving the pump. Using a DI tank alone will generally keep up, as it introduces very little restriction, but you will burn through resin very quickly.
That’s why having a buffer tank is so useful. You can feed it with an RO/DI. You just have to give it adequate time to catch up. I would use filtration for the final rinse, only.
I’m using just a DI tank, it will be hard on the resin, but honestly I’ve been worrying about this problen for weeks, and just want to be done with it haha
I’ll figure out morr effective solutions afterwards. 
Hey, I ended up buying your portable water softener and unfotunately the spots are there, although the white chalkyness is gone, the water spots on the black are still there.
It’s a little hard to see, but if you zoom in you can see them, and in person they are visible.
I used the housewash mix, just SH and a surfactant, and rinsed with the portable soft water softener. The rest of the house is white and looks perfect, it’s just these pesky black soffits and gutters. They dont scrub out, I went around and basically hand dried it, and they are still there.
Wondering if you have other suggestions?
I’m thinking about putting disclaimers in the informational pdfs I send to clients, although that doesnt help me right now haha
Have you tried just using some rinse aid for autos or dish washers. Would have been my first effort.
I have not tried that, what would the protocall be there?
Read the instructions on bottle. Would just try some in a pump up or spray bottle first.
Customer could have silicates in their water. The spots might scrub out with some OneRestore or similar acidic cleaner. But I wouldn’t count on it.
If @Henry_Grover_Jr has his notifications turned on, he might chime in with some suggestions. Or maybe @CaCO3Girl has some input.
I’d just refund them their money and roll on to the next job. Wasting a lot of time and resources going back and forth and fretting over this. There’s a million houses to wash without black accents.
I love that suggestion
100%. I was working off the assumption that that wasn’t an acceptable solution to the homeowners. But I shouldn’t assume.
I would try to spray some vinegar on it, I’ve used that on light buildup on windows…
I am not sure if that is an actual option. I’m actually being subcontracted for this job, so I’m talking to a company talking to the client. I’m relaying that option, though… A refund would make it all go away assuming it’s viable.
