Default remove linoleum adhesive from concrete floor - how to?

The linoleum is gone, but it left a pattern on the floor where the adhesive was, and some of the adhesive is still there. Total of maybe 70 square feet. This is not the black oey-goey type adhesive, it's the whitish-brownish stuff that is really hard.

I can't use any sort of strong chemicals because I am going to stain the concrete and I want to keep the composition of the concrete similar to the sections that did not have linoleum down. That leaves water and various mechanical means.

No matter what I do I will probably have keep it damp in case there is any asbestos ebedded into the adhesive.

I don't just need the surface smooth with no chunks of adhesive left behind on the surface, I also need the pores open so it will take the stain, and all the adhesive removed. Basically, I need it to be like the adhesive was never there.

Methods I'm considering using (any, all, or combination of):

1. Pour boiling water onto the floor and let it soak in real well to soften everything.

2. Use an air scraper (rent, or buy from Harbor Freight if it's not too much). My compressor puts out ~11cfm at 90psi.

3. Use an air needle scaler like this:

4. Use a diamond cup wheel on my grinder. Would probably need a dust hoodie for the grinder too, as this is in our laundry room and bathroom in our finished basement (at least it's next to the garage )

5. Use a wire cup brush on my grinder

6. Use a masonry grinding wheel on my grinder

7. Figure out what chemicals I can use that won't strip any lime from the concrete (the lime is what the stain reacts with), but will help soften / remove the adhesive.

8. Rent a wallpaper steamer for ~$20.

9. Screw the staining of the bathroom and laundry area, just scrape up the adhesive on the surface, then lay ceramic tile down over those two areas, and stain the other 500-600SF of basement. This is probably the last resort, as I would really like to just stain it all.

Any of you guys been through this before? Any advice, or preferred methods?

Try a citrus based solvent like this one:

Is that stuff similar to Goo-Gone?

Any chance of it "etching" the concrete at all?

Thanks.

I would call them and ask about etching but I wouldn't think it would.
I've never used Goo-Gone so I don't know.

When I did my shop floor, it had 3 different types of tile - the tar / paper lino, the white mastic like you have, and peel and stick. The only thing I found that would work was scraping and hot water. I would let it sit for a while, scrape, soak it again, scrape. Repeat.
I would think it would be next to impossible to get it clean enough to stain without physically removing the top layer of concrete via some method.

Clean the whole area with the citus remover. But start in one little spot that no one would notice and see what the stain looks like after applied on citus cleaned concrete. The citrus cleaner I used made quick work of tile glue. Just an idea

If it's hard and dry you could rent an orbital sander to sand it off...

i have a similar situation, mine is from carpet in the garage (in front of the door). i wonder if the cleaning etching process of cleaning the floor (to put down epoxy floor paint) would be enough to clean it up??? right now i am scrpaing it off with a razorblade, i only have about 4sf of it though.

I would say no. Epoxy needs a profile that feels like sandpaper. I prefer the grinding (with diamond cups) method for epoxy prep. I would guess that most epoxy failures are from inadequate prep. And, in many of those cases, the epoxy gets the blame.
See my epoxy floor thread:
