A spray Gun that connects to a regular home garden hose with a pinched high velocity fitted nozzle.  Underneath the spray gun just in front of the trigger is a threaded cleanser attachment section in which you can screw a reload canister filled with a hard or powdered crystalized biodegradable concentrate, that time dissolves with the mixture of water pressure from the garden hose.  About 1 to 1 1/2 hours of spraying each reload.  The cap from the cleanser canister can be flipped over where there is a threaded insert that is the same width of the reload canister threads and can be used to plug the gun for rinsing.

Environmentally friendly cleanser be used for blasting mold & mildew from: Aluminum & Vinyl siding, paint, stucco, brick, stone, sidewalks & driveways, shudders, roof top shingles, rain gutters, windows, doors, wooden decks, swimming pools, and more!  As much humidity and mildew as it is in Florida, I would like to start a pressure wash business out here, especially in the summer and spring!  So bad that if you don't clean your toilet bowls here in about two days it'll be black with mold by the 3rd day guaranteed! Imagine what I see growing outside in all this hot topical moisture?  Woah....!
