Gutter brightening goes a long way with increasing curb appeal. We are not responsible for results while following these instructions as variables can vary greatly but this is what we do.
BE CAREFUL! This stuff is strong, make sure you keep things around it wet such as siding and plants.
In a 5 gallon bucket, fill up about 1 inch of GUTTER GRENADE (found at www.pressuretek.com) and another inch or two of water.
Put a brush of choice on the end of a pole (our favorite is a green muti directional brush also found at Pressure Tek) and dip it in your bucket.
Begin applying the chem to the gutters in 8-10 ft sections at a time, periodically scrubbing the gutters. You should notice the gutters becoming completely white. Use this same bucket all the way around the house. It does not matter how dirty the mix gets, the active ingredients will still be effective for the remainder of the job, or until you run out of mix.
GUTTER BRIGHTENING DOES NOT WORK IN TEMPERATURES UNDER 60 DEGREES FAHRENHEIT
