I can't find the post talking about how Green Wash makes the bleach....bleach stronger. But I have a question.
Can Green Wash's bleach accelerators make bleach to strong that you risk color fading on vinyl siding or composite decking? Am I safe to assume as long as you stay in your 1% bleach range on these surfaces color fading will not be an issue?
We clean most composites at 1% and we might agitate with a brush, If we kick up to a stronger mix we just rinse sooner. I tell my clients that I use softwash systems methodology which includes Greenwash which allows me to use a lesser concentrate of bleach compared the guys that use bleach and dish detergent. I have no concerns about fading. You can always due 2 light coatings
Contact Doug Rucker about BT200. The microbes are absolutely safe on composite materials. We just used them on an original TREX deck that was red. Green mold , black mold, grease from the grill etc was pretty heavy on the deck, and it all cleaned up way beyond the customer's expectations.
I do agree with AC the mild SH mix will be fine.
Just don't use high pressure to rinse composite materials.
I've emailed Doug but just have not gotten around to order some. When you use this product what is the dwell time on the surface...for some reason I'm thinking that I read it should dwell overnight to let the microbes do their magic.
