Didn’t have on latex gloves and when spraying “insulating foam sealant” some got on my hands. THEN I made another DUMB friggin mistake, washed them in the sink!
Of course wife is pissed!
What do I use to clean the sealant off the sink? We used normal kitchen cleaners and none worked.
Thank you,
Not a plumber, but I do a lot of it. Expanding foam insulators like “great stuff” can be a pita to clean up. My best advice would be to scrape what you can with a putty knife and use a rough textured cloth dampened in water to get the stuff that’s real close to the sink. If you can shave it down like I said, it gets easier. What material is your sink and is it glazed or anything?
Get as much off as you can by picking and a plastic scraper (old spatula works well) then get the remains off with hot water and one of those magic eraser sponge looking pad things.
It’ll be stuck to your fingers longer than it’ll be stuck in the sink.
Yes it was “great stuff”. The bathroom sink is contractor grade and I don’t know what type of material.
Scraped off the heavy areas, then used one of those eraser sponges. Even sprayed with WD-40 without any success. Of course we used Comet etc.
I’m not a plumber but my butt crack is showing. (I’m sagging just for this thread.) IMHO this stuff only comes off by being worn off. You gonna have to scrape it pardner. That or leave it. Blow it off with your M4. That would work.
Acetone
Last time I used triple expanding foam, I got a little carried away. Ok a lot carried away but I digress. I used acetone and let it set with a good hour of contact time. Went in again and scrubbed it with a scratch pad and more acetone. Wear gloves…
LOL
The best & correct answer is to get the MSDS (Material Safety Data Sheet) on that specific product “insulating foam sealant”. It will have a specific product/part # etc. It will have a comprehensive breakdown to Exposure limits, eye care, breathing, toxicity, smoking, heat, ventilation etc.
Read what it says solvents will work correctly w/o caustic/physical damage to the material(s) your working with. Be advised that some solvents are caustic to breath or absorbed into skin etc. so a specific type of respirator or filter / ventilation / fans may be recommended etc.
It’s the correct OSHA etc way. LOL
Here’s a sample of a MSDS for a “Insulating Foam Sealant” made by DOW. There are others. 3M, DuPont etc. which is why you may need the specific part/product #.

After reading the link, I feel like the dumb ass Pakistan who killed himself from burning our FLAG!

acetone as mentioned above. that’s pretty much the universal solvent.
That stuff is hard to clean up.
Lay some tissue paper on the stain and soak with acetone. Let it sit a while.
Lol No worries brother, that’s why we share & help out rather than ad hominems.
After reading your suggestions yesterday, tried the following, until I purchase acetone and a plastic scraper this morning:
I placed three sheets of paper towels together & soaked in dishwasher soap. Left it soaking in the sink for about three hours and then removed a shit load of gunk with my thumb fingernail.
Thanks to all of you, maybe the wife will reward me with a little poontang! 
Acetone will not work on cured foam sealant.
