   Some tape adhesive residue would be water soluble, others thinner or some other solvent.A great place for Information, Comraderie, and a sucker punch.

   Sounds like they didn't try too much...or did they?
   Could it be as easy as sanding the effected areas with a 36 grit up to as Sphere says sandblasting. In other words trying the most gentle way first. Might be as easy as that. I would think that any liquid would take it further into the concrete. I'd probably even gently try a torch in areas and see how that works.

   Don't know what they tried. Just got the note as part of another communique, and I'm trying to find info and solution before they get too far into some alternative floor covering.

   From client: "It was blue painters tape mainly, but some duct tape.
   We had tried sanding, scaping with very sharp putty
   knife, alcohol. I have not given up. We have utility
   room floor the test cleaning and staining samples. "

   Any worries that it'll be absorbed into the crete and then affect the stain?

   Can't verify that, but used it alot when I repair boats, before paint.

   I'd try etching with a mild muriatic acid, then rinsing well.  Whatever they do, spot test before the whole floor.

   I believe I read that acid stains will not work on concrete after a treatment with muriatic. The reaction potential has been used up by the first acid.

   That may be, I'm no expert.  I have some friends whol stained some of their concrete, and acid etched first.  Their stain wasn't an acid stain though, they might have just cobbled something together with paint colorants and concrete sealer.  still looks good after 8 years.zak

   acid stains are basically, different salts that react with the cement to create colors. different salts, different colors. The acid is a mild 1% that weaken the cement so the salts can soak in. Some concrete are just too hard. so yoadd a small amount of addition acid to aid. If you acid clean the slab before staining, you have no cement to react with.

         4.5'' grinder and a wire cup brush?   I'm about to try this on some old outdoor carpet adhesive before I tile.  We'll see!
