How to clean epoxy resin tools and cups – clean resin from tools

How to clean epoxy resin tools and cupsLearning how to clean epoxy resin tools and cups is not only a great way to save money, but it’s also a thoughtful way to reduce the amount of waste you produce when making resin art, jewelry and crafts. Here’s how I like to clean my resin tools and supplies to reuse them again:

Step 1

Wipe off solid surfaces with a paper towel. Clean up as much as you possibly can while the resin is still wet. Once it gets sticky and starts to cure, the paper towel will stick to the resin.

Step 2

Clean the surface with a solvent like denatured alcohol or acetone. This will remove remaining residue. Safety tip: Wear nitrile gloves when doing this to prevent a skin irritation.

Step 3

Wash your cups and tools with a quality soap and water. Flip upside and allow to dry on a towel.

When cleaning silicone items, you can simply let the resin cure, then peel it off the silicone surface once hardened.


For plastic mixing cups, you can let the resin cure, then flex the cup. You will be able to peel a skin out of the resin cup. This is easier if you leave something like a toothpick or wooden stir stick in the cup to use as leverage.

Cleaning foam brushes doesn’t work well. Unfortunately, for your sanity, it’s best just to throw them away.

  1. Another tip for cleaning hands is a bit of cooking oil rubbed on and then washed of with soap and water it cleans quickly and easily

  2. I often see people applying a top coat of UV resin on their finished items with paintbrushes. How do you remove the UV resin or even epoxy resin from small paintbrushes without ruining the bristles? And is their a particular type of paintbrush that you recommend (i.e., acrylic, natural, etc.)?

    1. I wash mine with soap and water while they are still wet. I’ve never tried this with UV resin though. I have a hard time believing you can get out the UV resin before it starts to cure.

      1. So I’m going to ask something that may seem silly but I’m very new at resin; do you wash the hardner cups and resin cups separately? If you do wash them separately do you wash them at different sinks? Do I have to worry about this stuff curing in the pipes basically?

        1. Hi Leigh, I don’t wash my cups until I have all the components wiped out with paper towels and wiped clean with solvents. There shouldn’t be any residue left at that point to bother your plumbing.

          1. Hi Tisha, if all the uncured resin is out of the cup, then yes, it’s safe to wash in the same sink as your dishes. (That’s what I do.)

  3. I have a spray bottle of regular alcohol that I spray in my plastic and silicone cups as soon as I have finished pouring; it works well. Acetone also works well, but Nitrile gloves have a 4 minute tolerance for acetone, so change gloves if your clean-up is taking more than 4 minutes.

  4. I am so glad you posted this. I am the laziest cleaner. I let my mixing tools sit way to long, then hope I can peel the cured resin off. I will try to use acetone on the remaining bits next.

  5. I am searching for any help in finding how to protect large pours on canvas
