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 quality soap and water. Flip upside and allow to dry on a towel.

resin skin from silicone cup

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.

What else should you know about how to clean epoxy resin tools and cups?

If you have more than just a ‘little bit of resin’ leftover in your cup, be sure you dispose of it properly. This article details more: How to dispose of resin. If you find you are regularly mixing more resin than you use, this article will help: How much resin do I need?

Should you get resin on your hands during this process, do not use solvents like acetone and alcohol to clean them. Instead, use a baby wipe to remove as much residue as possible. Then, use a good quality soap to wash your hands. If they are still sticky, a pumice soap should clean your hands of any remaining resin residue.

  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.)

    2. I know this comment is old, but I just wrap brushes with UV resin in a small piece of aluminum foil. No light so it never cures and stays wet until the next use.

  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
    -how to protect floor from pours, a lot of pours (drips)
    -how to protect tops of wet pours on big canvas

  6. I didn’t get my plastic resin cup clean before it hardened and am having a hard time because a lot of it is just droplets but I can’t get it all because they are the measuring cups so pretty small. Any ideas, should I just throw them out??? Can I just put more resin there to measure and mix or even just measure or will that contaminate the new resin??? Extreme newbie here I’ve only done 2 things, alphabet keychains.

    1. Hi Jamie, have you tried flexing the cup to pop out the leftover resin? As long as the resin is cured, it won’t contaminate any future pours. I have cups like this too and I set them aside to use for the times I need extra cups to pour mixed resin into to color it.

  7. For UV resin brushes, once I’m finished I wrap them tight in foil. I have been able to reuse mine over and over again.
    Hope it works for you…..
    Love your advise on cleaning the cups.
    Thanks

  8. Hello. I am a lover of making resin items. I was using resin for months without issues and then I somehow started to have reactions to what we believe is the alcohol. I use a respirator mask, neo-prin gloves with nitrile gloves underneath, safety glasses and still have the same reaction. Once the alcohol is even airborne, my eyes swell up and get red and start to flake. I have had to go to urgent care 3 times and received shots, eye meds and ointments. To say the least, it is miserable. However, I don’t want to stop creating if I don’t have to. I have a lot of time and money invested in my supplies. I heard that you can use vinegar to clean as well. Is this factual? If not are there any less invasive chemicals that will clean it? Not really wanting to use Acetone or Lacquer Thinner. Tried denatured alcohol as well with the same effect. Please someone tell me there is hope. I can’t stand to stop but can’t continue the painful process and Dr. visits either. Please help.

  9. toclean my cups I let the left over resin harden and then pull it out.. I use Isopropanol to clean my surfaces and hands, it works really well

  10. Hi guys well just recently started crafting with resin and oh my gosh had ive had the worse messy disasters lol and tried alcohol and acetone and they worked ehh only a little ..its was so frustrating because then i would get resin on already finished items or one time i poured to much top coat to dome a fully done resin coaster and it dripped off the sides went under it as well just a mess and i decided since it was still wet to just wipe off the top coat before it cured off my coaster n just redo it another time before it ruined my coaster and then i would need to sand it down so i rinsed off all the resin easy and fast with VINEGAR. My coaster was saved still shiney not one bit of the resin on it so pretty much i use vinegar to remove resin messes. Its works 100 times better then alcohol i use vinegar for every accident even to wipe off prints i may leave on a resin object with my resin covered gloves by mistake.

  11. Great advice as always, Katherine! Just a comment about recycling and avoiding waste: having to use (clean) paper towels and nitrile gloves, which get thrown away each time and cannot be recycled, probably creates more waste than tossing small measuring cups full of resin. In this light, the best solution might be the one of leaving a toothpick in the cup and peeling off the cured resin to throw away the next day.

    1. Hi Susan, thanks for sharing that tip. I will do that as well if there is a lot of resin in the cup. Otherwise, I find I can’t get out all of the cured resin by grabbing the toothpick unless there is a thick pour at the bottom. Do you have that problem too or is it just me? 🙂

  12. Can someone help! Silicone molds became greasy after couple of uses although I haven’t used demolder 😭
    Please someone help how to clean them, because products are pretty hard when I take them out, but have a sticky film 🤔

  13. I recently started working with resin and I love it. I recently had a disaster with a paper weight. I put seashells in the bottom with a couple small real flowers with a butterfly. I filled my resin ball up noting I had to use 2 different resins. The next day I opened it up and the bottom had very little resin and there were places that didn’t have resin inside the ball and if that wasn’t enough it had a tit on top. It turned yellow so now I just call it my boob ball. It’s still sticky on the bottom too. Can someone tell me what happened?

  14. So I understand how to get the harden resin out the cup but how do you get the separate part a and part b cups cleaned that you do your measuring in?
