Hey, just went out to do a quote for cleaning these four sun screen panels. They are a kind of plastic-y material that is stained with some mold.
Do you have any idea if they will clean up, and with what? Maybe screen magic? Never used it before, but am loathing to scrub with detergent and have it not come any cleaner…
I would check the seams to see if there was a very tiny piece that I could clip off and test it in a very mild solution of bleach. My guess would be that its 100% safe. My mix would probably be close to 10 ounces bleach to a gallon of water
Give speedy screen a try. Since they are just hanging loose I would just spray the s/$t out of them with speedy screen really soak it. Then try rubbing it up with a dry strip washer.
those look like the Home Depot roller shades and I know the material is cheap. Out here in AZ they burn out in a couple seasons and the material can be ripped easily. Also the tan color tends to burn changing the color and that can’t be fixed or cleaned.
Okay cool, I will look into speedy screen and otherwise test with bleach. They are a few years old, so maybe tell the customer it might not turn out. I’m thinking $25/panel? They are doing the windows at the same Time.
OP, i think [MENTION=5152]wws[/MENTION] is on point. bleach is the way to go. but i think you’ll need to go hotter than 10 oz to a gallon. my personal opinion, and i may be wrong. but i always err on the side of overkill. if the substrate can handle a hotter mix, why not increase your odds that the first application will do the trick?
i would go 50/50 household bleach to water plus 5 oz of laundry detergent, pump spray it on. let it sit 10 minutes but dont let it dry, and then rinse off thoroughly with a garden hose. but do this first (VERY IMPORTANT)- color test a very small portion of it first- dab a little on with a paint brush somewhere unobtrusive and make sure the color doesn’t change or fade. you’ll probably be good to go and that mix will kill the mold quick.
The dilution ratio I gave was based on the effectiveness of housewash mix while pressurewashing. If it makes you feel any better about using bleach, at the last company I worked for I cleaned carpet, upholstery and window treatments for 12 years. Bleach would probably be my go to. You could also try sodium percarbonate or 30 weight peroxide

Generally speaking SH (bleach) will only discolor/bleach organic fibers but leaves man made fibers unharmed, tis why my uniform is polyester.
Once it penetrates the stitching/weave it wont come out with a house wash mix you will need a roof strength mix.
Surfaces which lay horizontal tend to be much harder to clean than surfaces that are vertical, gravity and all.
Close, not all man made fibers are bleach resistant. The ones that are would be solution dyed fibers like polypropelene, olefin, polyester, and some times nylon can be as well. Solution dyed means that when the fiber is made the dye is mixed in with it so it goes all the way through the fiber. Just like a colored piece of plastic. A lot of man made and all natural fibers are made and then color is added to the fiber afterwards. The dye soaks into the amorphic regions of the fiber and color it that way. Fibers that are dyed in this manner are still able to be bleached out.
That shade can be cleaned with house wash. I would bet a good chunk of change on it.
Gathering from input here, probably the best thing would be to try the heavier ratio first on a small piece, and if it doesn’t burn or discolour it is all good.
So… Is soft brushing it on and then rinsing after 10 min a good first shot? And if it is still on there try agitating with a harder brush?
In terms of pricing is 25/panel sounding close? Looks like around 15/20min a panel if it needs scrubbing
Hey wws, definitely not skipping your posts. I thought you guys said the same thing, and going back youre saying start mild. I don’t really have any experience with bleach so maybe it looked the same…
