I have two gutter-cleaning products that I recommend: Streak Getter, which I found somewhere on the Internet, and Krud Kutter which I purchased at Lowe’s. Both work about equally well. All it takes is a sprayer, a rag and some elbow grease followed by a water rinse. My streaked, gray gutters are nearly as white as when they were put on the house, 10 years ago. It’s clear that over time, tar and debris from the roof shingles greatly discolor the gutters, and the years do a number on the siding as well.
After the gutters were done, out came the vinyl siding cleaner, Olympic House Wash. This did not work very well when following the directions (spray on, wash off with a hose) but by using a rag and hand-washing the siding after spraying it on it all ended up much cleaner. What a difference!
I know that many homeowners will hire crews to do this kind of work, and many other homeowners won’t even bother to ever clean the exterior of their home; but to some of us it’s a labor of love. I needed a long weekend to get psyched to do the work, but the result is a noticeably brighter exterior.
Now I need to find a good cleaner for the brickwork on the front of the house, and maybe those pesky building inspectors will stay away for a while.
