Make your house sparkle and shine with a power wash using ZEP concentrated cleaner! Easy to use, ZEP cleaner lets you tackle the dusty and dirty grime, bird droppings, mold and mildew, and other smears that’s can show up on siding, overhangs, sashes and doors. Economical and effective, ZEP makes your house the cleanest on the block. Works great on vinyl, fiber board, cement board, and metal sidings. Great for downspouts and gutters, garage doors, and exposed masonry foundations.

I mixed 1 gallon of this siding cleaner with 1 gallon of water and with a spray bottle sprayed vinyl siding a couple minutes before using power pressure water and it helped loosing dirt and green mold.
I don't believe you can get up to 20 gallons with 1 gallon of this cleaner, it would be useless.
I sprayed on gutters but didn't work at all, so have to find something stronger.
Also I don't know if is plant safe as other brands.

In my efforts to not use bleach I spent more money and wasted more time. I followed the instruction and kept the area wet for 5-10 minutes, actually sprayed it 3 times. The power washing was done at a distance of 3 -6 inches which can cause damage to wood siding and I still had mold stains. It appears the stain that did lighten was due to the power washing itself. When I use bleach all that is needed is rinsing.

I washed my windows with your streak free window cleaner
I was excited to try your window streak free cleaner. I wash my outside windows every 2 to 3 weeks to keep the windows cleaning our house. I washed my windows yesterday while it was cooler and Cloudy. I looked at my windows this morning while the sun is shining on them and they look the worst they've ever look you can just see the dirt and grime on the windows. Considering it is a streak free product it's amazing how dirty they really are I think your product does not work well. I'm excited to hear back from you about a possible solution for your product. I would love to be able to send you a picture how dirty they are
