Couple of bushes. That was from the 12v though. 3% mix. I always prewet and wet again during the dwell. Missed two out of 100.
Never down streaming

LOL, I thought that was going light. 1oz per gal is recommended for direct app and what I use on roofs if not slightly stronger. Downstreaming with 10-1 in theory you’d need 10oz per gal, but from experience can go a little less.

Always do a real light final rinse after it’s partially dried and had time to run out from a distance.

Seeing this article, this may have been part of your problem. Do you have hard water up there.

Yeah we have some hard water but I test the water before I use it. I have a waterfed pole system that came with one so I’m always checking. This house had fantastic water. I think your right though I went back and hit the spot that had dried with just water and all of that stuff came off. I need to stand back and hit at a more straight angle and then make sure to wash again if need be, those streaks are from holes in the vinyl that get rid of water I’m fairly sure. The soap was the reason racer thank you, it wasn’t clinging to the surface allowing the mix to do its job… Now it sticks right to it.
Mix that worked for me
DS 5 gallons of 10.8 liquid chlorine
21 ounces of snotmenade
I got that article in my inbox today.
I can’t believe they’re telling pressure washers to take water samples to a lab for analysis!
WCRA sell TDS Meters for like $17. Everywindow cleaner who has a Pure Water system uses these daily.
It’d make more sense for these guys to sell these cheap little gizmos than recommend lab samples!
Also… 3 grains, >60ppm won’t do sh#t to your soap. It’ll be up around 200ppm before you notice a difference. Even then, the main problem will be mineral buildup over time in your hot water boiler… not the effect on your soap

Apparently the price has gone up a bit, still waaaaaay cheaper than a lab test. Plus you can use it whenever you want!
Yep, I have one. Our TDS here is around 25 so not a big worry for us. I’ve never had to deal with. He’s up in Canada, so had no idea what his was.

25! 25!! 25!!!
By $turnover I’m still mostly a window cleaner.
Do you know how much money I’d save if my TDS was 25!!
Atleast you’ll never have to worry about streaky windows after pressure washing. They must turn out close to perfection after a good rinse!

I have considered throwing a couple of Salt rocks in the buffer tank for this matter, does anyone think this should work or not? I didn’t try though, have no equipment yet.
Meh I honestly didn’t find they got that clean! A lot of new first customers with windows this year which is great… But first cleans can be brutal. Me and my steel wool and razr blades have been best friends 
There are things that you can put in any water solution that will assist you GREATLY with hard water. We call them Chelators. Does anyone have access to:
EDTA (39%)- (Liquid) Ethylenediaminetetraacetic acid - Wikipedia
Sodium Gluconate (powder) Sodium gluconate - Wikipedia
NTA (Powder) http://doc.ccc-group.com/msds/english/651100.pdf
If you get the powder you want to mix it with water before you go throwing it into SH. I know they say they are acids but it won’t affect your SH

Racer,
So that’s about 0.65% SH hitting the house if it’s 18:1, right?
Sorry mate, that comment about the windows was for Racer and his 25ppm TDS
Just re reading answers that people have posted to refresh the brain. When you said you did almost 20 houses before you touched a paying customer…was that friends and family or were you offering free services… I can barely find two houses of people I know that have vinyl siding lol

Friends, family, neighbors, and I even asked the owner of the company I worked at full time (great commercial before and after pics). Just be honest and tell them your just starting out, would be willing to clean their home/business for free and all you would like in return is to be able to use the before and after pics for your website. I only “practiced” with people I had a rapport with; since I was waiting on insurance and LLC to be finalized.
You can come wash mine! No algae but dusty! I haven’t had time!
I have not read through all the comments so I may be beating a dead horse here but I would recommend a test spot of 50/50 12.5SH and water, 6% is strong but if it works you will know you’re mix is too weak. Also, when downstreaming I would not dilute your SH because your machine will dilute it for you. 10:1 with straight 10%SH will get you at 1% l, if I’m not mistaken and that should be plenty good for vinyl. If you are cleaning brick, don’t even attempt to downstream, you will need a pump sprayer or an xjet. I just purchased my xjet but have yet to use it.
