Residential Concrete Chemicals...What Do You Use?

Question

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.

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 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.

5 lbs.trial $10.00, 50 lbs. $85.00, 100 lbs. $160.00, 500 lbs. $750.00

This sudsing alkaline powdered detergent is designed to clean heavy grease, soil, oil, and scuff

marks from unpainted concrete. Also is an excellent booster for your regular detergent when

you need extra cleaning power. USDA Acceptable.*
