Ok, its 4 AM and I just got up from the kitchen floor where I am attempting to remove adhesive from around underneath the cabinet edges and around the dishwasher and trash compacter where it not only is adhisive but, I don't know, grease?
I was scraping under the sink cabinet and opened the doors to get more clearance and there was a spray bottle of 409. I thought why not? I have been down here for about 4 hours now. So I sprayed some 409 on the concrete around where I had been scraping using a wood chisel because it is sharp.
Behold it worked wonderfully. I not only loosened the grease but it also softened the adhesive so it was much easier to scrape off. Then I just cleaned the area with soap and water to remove the residue and was done. Just thought I would post this in case it helped anyone else.
