concrete

[pee dee]

What have yall fellows had the best luck with cleaning mildew/mold or whatever the black mess is off of concrete? I can clean it using just pressure with the pressure washer, im just not making the kind of progress I would like. Muriatic acid?

Be careful with acid. You can burn your concrete.

My brother had a guy do the outside of his house and concrete driveway without a pressure washer. From what I understand, he has it set up in a contraption similar to miracle grow that you attach to your water hose. Spray it on, let it sit, spray it off. No scrubbing and no pressure involved. The house looks brand spanking new and the concrete which is close to 10 years old looks new with the exception of some of those stains that just won't go away.

Let me see if I can find out the name of it.

Give this a try before you invest a lot of time with a pressure washer.

jomax is the cleaner
if using a pressure washer use a high gpm unit(more important than pressure) and a turbo nozzle

I just picked up a new PW at Costco. 2.4 GPM, 3000 PSI and powered by a 190 cc honda motor for 269 bucks. Best price for a quality unit I could find.

Well, what worked?
