Sup, so I want this to serve more of as a “what a noobie should NOT do” when soft washing a home.
Little background, under 2k square foot home & very badly oxidized. The house gets direct sunlight most of the day on all 4 sides of home, no trees in sight.
Customer wanted the house power washed & windows cleaned.
Cool, I gave them the quote, and showed up to get started.
Being a newbie and learning, I showed up to do the house wash while my helper was cleaning the screens and doing the inside windows (I do primarily window cleaning & power washing is an add on).
As I mentioned the house gets direct sunlight most of the day and on the day of service it was about 80-90 degrees.
WHAT NOT TO DO: What I proceeded to do was downstream SH on all 4 sides of the home FIRST, about 1-2% downstreaming. Like I mentioned it was a very hot day and the solution dried up fairly quickly. Then I did a half *** job rinsing it with my 2.5gpm pressure washer.
Got paid for the job and thought all was good then received a text a few days later that there are streaks all over the house.
Here are the pics of the streaks:
I thought it was oxidation (not even knowing what the word meant) or dirty runoff, which is what I told the customer and that I could fix it.
I come back and try to downstream again and rinse off but it’s not coming off. I told him I would have to be back, that his house is badly oxidized and that I would need a different solution to remove.
Upon further research and speaking with others more knowledgeable than me, I figured that I removed the oxidation in certain areas and not in others which is what caused the blotchy areas.
I would need cleansol bc or a similar chemical to remove, I used a chemical called Cleanse All to remove it.
My process: I prewet the siding, this time I worked in sections. I prewet the siding, used a sprayer with half Cleanse All, half water to apply the solution, and then used a soft brush to brush it across the areas I sprayed, and rinsed it right after afterwards (DO NOT LET IT DRY).
The results after:
Oxidation removed and fresh siding left behind!
All it cost me was about $20-$30 for the chemical and about 3 hours of my Saturday, not an insurance claim of repainting or replacing siding!
Soft washing can be easy money… until it’s not.
Proceed with caution and do your due diligence.
Ever since this job I have been working in sections, not doing the whole house at once. Prewet the plants, apply chem, let it dwell a bit, and rinse off.
ALSO, use low pressure tips and LIGHTLY apply the chem and rinse off!
