Help from the OT builders please.

Had a slab poured for my new master suite addition yesterday. The cement truck used the side gate to access my property and parked on the side drive which is made of an exposed rock and brown stained concrete mix. Went out there today and they made a pretty big mess with run off all over the drive that is a very light gray color. If the drive was normal concrete it wouldn’t be that big of a deal but this looks like arse. Will power washing remove concrete like that on top of other concrete or is there another method?

HCl will possibly clean it up.

They are nice folks. I don’t think I need to call them names.

Just came to OT because I couldn’t reach them first thing and thought the solution might be time sensitive. Guess not. Will try powerwash and then Hcl as suggested.

Call the ready mix company and ask them if there’s an easy way to clean it up. If anyone knows how it’s probably them.

You may want to pick up an acid brush head for the muriatic acid. An extra $3-5. I try not to ruin pump sprayers with that low ph, so i normally mix in a 5 gallon bucket. You can pour it from there or dip the brush in. Probably won't 100% clean up, but it definitely should improve the situation noticeably. I'd use the acid before pressure washing btw.

Would muratic acid not mess up the stain on the concrete?

Scrape it off asap. decent chance it didnt bond well. after that you may need to power wash. You may have a little more work if the stain took. You can try the muriatic acid(diluted of course) BUT you will need to vaccum it up after washing it down well with water.

If none of that works...may need to resurface the drive if it looks bad enough.

Absolutely this too... using something softer than the concrete/rocks is recommended. I use what's on the job site, like a door shim, piece of 1x2, whatever + plus some light hammer tapping. Occasionally used a flathead screwdriver, but it can leaves marks.

sounds pretty minor. Stuff probably going to disappear on its own unless the driveway was very clean.

What were you doing with a cement truck at your house? Concrete finisher is going to have a hard time finishing all that cement.


Yes, power washing will get it off.

Nah. I bought a house that used to be the guest / party house on the back of a larger estate. It doesn't have a master suite. I have been living in a guest bedroom with a hotel sized bathroom for 7 years building up to this project. IF I had bought the whole estate, now that would be a not subtle brag.

Even less braggy, I inherited half of the property and mortgaged my soul to purchase the other half. When the entire renovation is done, it is going on the market. It is WAY too much house for me. The yearly property taxes alone are staggering.
