Chemist here. You will need a chlorinated organic solvent. Using petroleum, solvents and distillates for cleaning floors is common and dangerous, and can cause brain damage and cancer.

The most readily available would be tetrachloroethylene. More commonly referred to as Brakleen Red. Any turdzone will have it. They even make an extra large can with a jet spray nozzle. Evaporates clean with little residue, is not flammable, and prob the strongest adhesive remover available commercially. A lot of times it’s wiped off the shelves it’s not a secret. That and some people use it to clean pharmaceutical freebases of illicit drugs. Just saying.

Once it penetrates underneath it will be a cake walk. It’s also heavier than water, so it will sink and continue to, displacing water upwards.

Your next option, although advise against it would be toluene. OR it’s shitty little brother xylene. These two petroleum solvents are capable of melting plastic at room temperature. Also toxic, flammable extremely, and pricey. Buying large quantities of these may give you some funny looks at check out. because they to, are often involved in the production of methamphetamine. I would stick to a max of 2 gallons or less. That would be normal.

Lastly, I’ll suggest the most powerful cleaning substance that I’m aware of called piranha solution. It is a combination of concentrated virgin sulfuric acid(Kleen out) mixed with 3% hydrogen peroxide. Always add to acid never add acid to anything. It must be mixed in a glass vessel, because within seconds it will reach upwards of 300° and be boiling independently by itself. This is what the cartels use in 55 gallon plastic drums to dissolve the victims in. from what I’ve heard, it can chop down a whole body in less than a week. Me personally, I just use it to clean glass wears.

There you go, buddy there’s ya hitchhikers guide to clean floors
