Why Cleaning Resin Cups Matters
Keeping your resin cups clean is more important than you might think. It helps prevent problems in your next project, keeps your workspace safer, and saves you money on supplies.
- ✅ Resin is sticky and tough to remove once it cures.
- ✅ If you don’t clean your resin cups, leftover resin can mix with your next batch, causing color problems or sticky spots.
- ✅ Dirty cups can also make your workspace unsafe, especially if you use harsh chemicals to clean up.
- ✅ Taking a few minutes to clean resin mixing cups saves money, keeps your projects looking great, and helps you avoid health risks.
What You Need to Clean Resin Cups
Before you start cleaning, make sure you have the right supplies on hand. A few basic tools and cleaners will help you tackle both wet and cured resin with ease.
Gather these supplies:
- ✅ Nitrile gloves (to protect your hands)
- ✅ Paper towels or old rags
- ✅ Isopropyl alcohol (at least 91%) or acetone
- ✅ Wooden popsicle sticks or plastic scrapers
- ✅ Warm, soapy water
-
✅ A trash bag for waste
For silicone cups, you may also want a non-stick spray or a mold release agent to make cleanup even easier.
When Should You Clean Resin Cups?
Knowing when to clean your resin cups can make all the difference. Cleaning at the right time will save you effort and keep your cups in better shape.
- Right after pouring: Cleaning before the resin cures is the easiest. Wet resin wipes out fast.
- After it hardens: If you forget and the resin hardens, you can still clean resin cups, but it takes a little more effort.
The longer you wait, the harder it gets to clean resin mixing cups. Try to clean up as soon as you finish pouring your project for the quickest results.
How to Clean Resin Cups Before the Resin Cures
Cleaning your resin cups before the resin hardens is the easiest way to keep them in great condition. Here’s a simple step-by-step method to get them sparkling clean while the resin is still wet.
Steps:
- ✅ Wipe out as much wet resin as possible with a paper towel.
- ✅ Pour a little isopropyl alcohol or acetone into the cup. Swirl it around to loosen any leftover resin.
- ✅ Use a popsicle stick or plastic scraper to get into the edges.
- ✅ Wipe again with a clean towel until the cup is clear.
- ✅ Wash with warm, soapy water and let dry.
Tips:
-
💡 For silicone cups, you can often just wipe them clean with a paper towel and a bit of alcohol.
-
💡 For plastic or glass cups, be gentle to avoid scratches.

How to Clean Resin Cups After the Resin Hardens
If you missed your chance to clean while the resin was wet, you can still get your cups clean after the resin has cured. Here’s how to do it.
✅ For silicone cups:
- Gently flex the cup to loosen the hardened resin.
- Most of the time, the cured resin will peel or pop right out in one piece.
- Use a wooden stick to nudge out any bits stuck in corners.
✅ For plastic or glass cups:
- Use a popsicle stick or plastic scraper to break up the cured resin.
- If the resin is stubborn, put the cup in the freezer for 30 minutes. The cold makes the resin shrink and easier to pop out.
- Wash the cup with warm, soapy water after removing the resin.
If you use a lot of resin, consider using only silicone cups. They make removing cured resin much easier.
How to Clean Different Types of Resin Cups
Different cup materials need different cleaning methods. Here’s how to keep your silicone, plastic, and glass resin cups in top condition.
✅ Silicone resin cups:
- Best for easy cleanup. Just peel or pop out the cured resin.
- For sticky bits, use a little isopropyl alcohol and wipe with a towel.
- Avoid using sharp tools that could tear the silicone.
✅ Plastic resin cups:
- Clean while the resin is still wet, or use a plastic scraper for cured resin.
- Do not use acetone on thin plastic because it can melt the cup.
✅ Glass or metal resin cups:
- Use isopropyl alcohol or acetone for both wet and cured resin.
- Scrape gently to avoid scratching the surface.
- Glass is easy to reuse, but be careful not to drop or crack it.
