Anyone have a solution for removing red chaulk dust from concrete?
I snapped a series of lines on a concrete patio to make relief cuts in the appearance of grout lines. Now I am getting ready to stain, and the red chaulk has not washed off.
I tried mild soup and water with a scrub brush. It removed most, but not all.

pour new concrete
would an acid wash work?
You have to be careful using any type of acid especially if you are using an acid stain. Defeats the purpose of the stain. Won't work as advertised. The company I purchase stain from stress to never use red chalk, only blue for marking lines. I know this doesn't help in regards to removing the red chalk, but if it were me I would use a TSP product and a lot of elbow grease. If the stain is not a acid based product a mild solution of Muratic should do the trick. Maybe BB will step in.

I started with blue chaulk, but it kept washing off on me. Then I read about using red chaulk on concrete. Didnt realize it would stick around this long.
Any issue using a strong soap or cleaner solution?
My fear is using something that will cause the stain to not adhere properly.
Thx
I don't think you would have a problem with the stain adhereing as much as seeing the lines of the chalk after staining. I utilize Kemiko stain products and they recommend cleaning with TSP. Anything else will change how the stain comes out on the concrete. If I were you I would consult the manufacturer of the stain you are going to use to be sure you get the results you desire.

Red chalk is permanent.... guess you are just paying the price for experience or.... not consulting someone that knows better

Nothing in this world is permanent.
Thanks for all the replys.
Bleach solution worked ok, but vinegar(wife's suggestion) took off all the chaulk residue with very little scrubbing.
Good to see that you got the stuff removed. I would suggest that you now do not use an acid based stain. Vinegar being an acid would have already reacted somewhat with the lime in the concrete thus possibly rendering any affects you desired from the stain useless or not uniform.

Thanks for the info.
The stain is Styrene Acrylic. Not sure how it holds up compared to acid based.
Styrene Acrylic., that is not stain, that is paint, it is worthless, it will peel like paint in couple years. check out:http://www.acid-stain.com“Our country! In her intercourse with foreign nations, may she always be in the right; but our country, right or wrong.”
vinegar will eat concrete. thats what I use to clean my concrete tools.“Our country! In her intercourse with foreign nations, may she always be in the right; but our country, right or wrong.”
I would listen to Brownbag and post on http://www.acidstain.com about your situation. The product you mentioned is a paint, not an acid stain. Mike

I thought they magically disappeared on their own. We spend big bucks for layout guys to snap lines and yet the carps/plbrs/elecs/etc always say they can't find the layout lines to measure off of..
Try diluted Muriatic Acid....
Stained concrete companies to em "No red chaulk." Maybe some bleach added to yor scrub solution. I don't know.
Wouldn't an oxidation bleach and a pressure washer take care of it?
thats why its call dead red, it doesnt come up. but a wire wheel in a drill will help“Our country! In her intercourse with foreign nations, may she always be in the right; but our country, right or wrong.”
From Irwin's literature:
Black is the most permanent color, followed by Red. These weatherproof colors leave lines that remain visible after weeks of rain and wear and tear on the worksite. Applications include framing, roofing, steel & metal fabrication, cutting through concrete & stone and marking slabs.
I like the pressure washer idea someone had . . .

Install steel pallet racking in warehouses, many years ago more than 15, guy from Sherwin Williams (paints)told me never use red chalk when stricking lines. Will show thru when they seal floor.
You might try a pressure washer. I had to remove some lines on my slab last year, and the pressure washer worked well.
