Have a 5.5 gpm machine and a 10 to one down stream injector pulling from a 5 gallon bucket what would be my ratio of sh and water to achieve a 1 % mix for soft washing just getting started so forgive me for the newbie question
You have a 10:1 DSI, that means your DS injector will downstream 10% of whatever strength you have in the bucket you are pulling from and 90% water from your pressure washer. I am sure you have to learn calculating this yourself before getting started. IE. If you have your bucket filled with 12% SH only (undiluted), you will be down streaming 10% of that strength, and so on for any strengths of SH in the DS bucket. So it all depends on the strength of your SH in the bucket, you’ll DS 10% of it’s strength if your DS is down streaming exactly 10 to one as you said.
Thanks much appreciated just stepping into the biz and there is a lot of stuff to know got about 100 hours into watching YouTube but this forum is a game changer been reading whenever I got extra time trying to gain some confidence before I start advertising
You might want to test your injector as well. Every set up is different. A chemical injector will pull different ratios based on gpm, hose length, size injector, etc. I have a 5.5gpm machine with 200 ft of hose with a 2.1 (3-5gpm) injector and it pulls a 14:1 ratio. At the end of the day it’s some trial and error as well. If the mildew is not turning a brownish color and starting to dissipate within a few minutes just add more SH. The ratio hitting the wall will work well as long as it’s about .6%-1%. You don’t need more than that for washing vinyl.
Thank you can’t stand the 9 to 5 rat race making others money done some research on small businesses and this power washing thing sounds great
the only thing you shud worry about.
We’re buying our machine next week. How do you determine your injector pull-ratio?
It’s like deja vu all over again
No, It’s like deja vu all over again
Pete and Repeat sitting on a log. Pete fell off. Who was left?
Who was on first, I believe Why was left…
At least that joke had the desired effect on somebody…
Can you xjet that on, or do you have to use a pump sprayer?
I heard that
Are they still crispy? I trust ya but dang that seems like it’s going to turn into a soggy mess
I thought the same thing when I made the first batch. They are as crispy as cheezits
It doesn’t help that when today’s pressure washing geniuses say 1%, 2%, 3%, etc… they really mean 10%, 20%, and 30%
