Bought 1 gallon of Ygiene-206 last week off Amazon.Com.I have used it on a deck(boards look like new)Disinfected and cleaned shower stall with it,leaves a nice fresh scent (unlike Bleach)and cleaned about 400 sq. ft. of aluminum siding(it also looks like new)I did not use any type of scrub brush or sponge.You just spray it on,wait 2 or 3 minutes and pressure wash off,that simple.I am totally impressed with Ygiene,by the way I still have 1/2 gallon left.I will be writing a positive review on Amazon this week and am going to contact Home Depot corporate offices this week to see about stocking Ygiene-206 so it is readily available to us,instead of wating 2 days for delivery through Amozon.GOD BLESS and happy trading
