I have done loads of these and every one of them has been a numpty!
I would get your hands on of few different strippers as what works on one doesn't work on another. It's impossible to dissolve this stuff unless it's only a couple of years old and water based. Some come off with hot neutral detergent. It will take ages to clean down all the kit at the end of it so budget for that.
Also you can't just chuck it in the drain. You need to separate out all the glue from the effluent. We use a mop bucket and pour it through a wringer.
The best method I have found so far is to apply which every stripper works best, usually neat, with a watering can and fine rose. Leave it till its almost dry and absorbed the stripper then use either a scarifying brush or hipro pads to break it up. vac then re apply stripper and vac again. Often a couple of laps with a scrubber dryer afterwards can be beneficial. Qualify with the client that ther may be some scratching of the panels. This can often be buffed out with a dry green or black pad when the floor is dry.
Sometimes it can be quicker just to spray about 50m2 and hit it with a floor scraper depending how thick it is. Usually on older solvent based adhesives this is the only way. 3 guys in a line on applying, 2 scraping and swap position every 5 minutes.
There is some nice tooling just for glue and adhesive removal but they jus don't work on access panels they are better for concrete.
