Residential Concrete Chemicals...What Do You Use?

[propressurewashing 17]

What chemicals do you use for residential driveways, walkways, and patios? On most of my projects I don't use anything pre-wash but I'll downstream a weak bleach mix after cleaning on really dirty projects. What do you all use/recommend pre-wash and post-wash on typical residential concrete?

Daniel, I mentioned to you once about "Harcos" for 12%. Spray your driveway with it after the initial cleaning. But not so heavy that it runs down drains on the street. Just enough to cover the surface area. Let it do it's magic and you're done.

I also mentioned that you are welcome to contact me anytime if I can help in any way.

12% is so expensive around here....I go to Ramteq in a pinch but it is almost $6 a gallon! Thanks for the tip!

Again - You need a signature. Please add it.

p.s.. f-18...might not be the best thing for that building. Safe restore or similar might be better.

I don't use anything..............I try to keep the drains chem free. If there was heavy algae, mold or mildew i'll do a lite bleach spray same as Adrian.

I use R202 from DCS (Formerly Delco). Mix the powder in a bucket, downstream, let sit, then powerwash off. Great results. Haven't harmed any plants or grass.

Well, like I said.

Harcros is 1.75 per gal. Minimum 55g drum. Well worth it.

The strength is more like 15%.
