I have been wanting to clean the columns on my house for a while so I went to Lowes to look for a cleaning solution and I came across this stuff.
I bought a scrub brush because I know some of these products say they will work without scrubbing but they seldom do...
This was a picture of my column BEFORE:
I sprayed it down and got ready to start my scrubbing but then the magic happened... I didnt touch this column with anything but my sprayer and then hosed it off... this was AFTER:
I tried it on a few other items like the vinyl windows, my front door, the vinyl soffitt, the gutters, and a small area of siding... WOW... it worked great on everything. So if you have some mold or discoloration on the North side of your house like I do, you might want to give this product a try. It was $20 for the jug and it makes 20 gallons of spray.
P.S. I know I need to paint my columns... It's only been 3 years since I built my house... gimme a break.
