This applies to both liquid flex seal and the spray can stuff. The only unique product removal is the tape.

Flex Seal is waterproof, but only after it has cured 100%. That takes 24 hours, so until then, water is your friend.

Soap with ground pumice, coffee grounds, activated charcoal, sea salt, or jojoba beads in it is going to be a lot more effective than regular unscented stuff. If bar soap doesn’t work, try using coconut oil or dish soap with orange in it.

In the future, always wear rubber gloves when you’re working Flex Seal. If you have any questions in the future, call Flex Seal’s customer service at (833) 411-3539.

For cars specifically: Follow these instructions, but use toluene instead of acetone, which will almost certainly strip your vehicle’s paint job. Some people have had success getting Flex Seal off of cars with WD-40 or Goo Gone. You can try using one of these products instead of toluene. Just FYI, acetone is the same thing as nail polish remover.

Reload the cloth with more water and acetone if you feel like your rag starts to lose its efficacy.

Test mineral spirits in an inconspicuous area first just to confirm that it won’t stain or damage the material. Many people have had success using Goo Gone and WD-40 on clothing or wood, but test it first to make sure it won’t ruin the material.

With clothing specifically, if the Flex Seal has fully cured, you’re going to have an extremely difficult time getting it clean. It may take multiple rounds of scrubbing to get the Flex Seal up. Depending on how long the Flex Seal has been allowed to dry, you may not be able to remove it entirely from your clothes. If you can’t get it out after multiple attempts, try dry cleaning instead.

Flex Seal tape is extremely difficult to remove once you’ve applied it to a surface. This is going to take a fair bit of effort. You’ll 100% be able to get the tape up with enough elbow grease, though.

You can try using Goo Gone or WD-40 in a pinch, but it’s unclear just how efficient these methods are.

Take breaks as needed. Depending on the size of the tape strip, this may take a while.

You can use a chisel to scrape away any especially thick globs of residue as well.
