Quick answer

Wipe up wet epoxy paint right away with paper towels, since it hardens by chemical reaction. For paint that has cured, test a general-purpose cleaner first, clean with a soft damp sponge, then rinse and blot dry without letting anything soak.

  1. Epoxy on skin: use a waterless skin cleanser, then wash with soap and warm water. Never use solvents.
  2. If epoxy gets on your clothes, change them right away.
  3. If epoxy gets in your eyes, flush them with water for 15 minutes and get medical attention if discomfort lasts.

Epoxy paint on a bathtub gets stubborn quickly, because it hardens by chemical reaction and the window to wipe it up is short. Fresh drips wipe off cleanly, but cured paint takes more patience, and what's safe to use depends on whether your tub is acrylic, fiberglass, enamel or cast iron. A fresh spot may come off in one session, while older paint often needs several gentle passes.

Wipe fresh epoxy paint drips off the fiberglass tub with a damp cloth before they harden. Avoid abrasive pads on cured paint, since they can dull the tub's surface. If the drips have hardened, a pro can be worth the call before you go any further.

Step by step

0 of 7 done
  1. Step 1 of 7

    Wipe up wet paint first

    If the epoxy is still wet, wipe it up with paper towels before it cures. Fresh paint comes off with much less effort than paint that has hardened. If any gets in your eyes, flush them with water for 15 minutes.

  2. Step 2 of 7

    Test your cleaner first

    Before you clean the stain, test any cleaner on an inconspicuous area of the tub. Check for dulling or a change in color, and only continue if the test area looks the same.

  3. Step 3 of 7

    Wipe with a soft damp sponge

    Wipe the spot gently with a soft, dampened sponge or cloth. On vitreous china, use mild soap and warm water instead of anything stronger.

    Tip. Keep the sponge damp rather than dripping, so you aren't spreading water over the rim.

  4. Step 4 of 7

    Use a general-purpose cleaner for heavy soil

    If the paint is still heavily soiled after wiping, apply a general-purpose cleaner listed for your tub material. Put it on the sponge and work it over the spot rather than pouring it onto the tub.

    Careful. Don't let cleaners soak on surfaces, and rinse overspray off nearby surfaces.

  5. Step 5 of 7

    Rinse right away with water

    Rinse the tub completely with water as soon as you've applied any cleaner. Rinsing right away keeps the cleaner from sitting on the finish.

  6. Step 6 of 7

    Use abrasive cleaner only on enamel or vitreous china

    For a stubborn stain on enameled cast iron or vitreous china only, use a soft abrasive cleaner sparingly. For a mark on enameled cast iron, a cast iron cleaner removes marks and restores shine.

    Careful. Never use abrasive cleaners without water.

  7. Step 7 of 7

    Blot the tub dry

    When the spot is clean, blot the area dry with a soft cloth. Then check the sheen against the surrounding tub to see how far you've got.

Best products for epoxy on bathtubs

Choose a general-purpose cleaner labeled for your tub material, and a cast iron cleaner only for enamel marks on cast iron.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on bathtubs, and its directions fit the steps above.

Finished the steps? How does it look?

How to tell it's working

The area is clean when its sheen matches the tub around it and the sponge comes away with no paint on it. If the finish looks dull or scratched after cleaning, stop and move on to the professional route rather than pressing harder.

What changes for yours

Adjust for your bathtubs

Epoxy paint drips

Drips are usually small and hard, so work on them early while the paint is still wet, using paper towels. Once they've hardened, they're the same job as any stubborn spot: test first, use a damp soft sponge, and don't let cleaners sit.

Don't chip or scrape at drips on acrylic, since abrasive pressure can damage the bath surface. If a drip won't lift with the gentle steps, stop there and move on to the stronger options below.

Fiberglass tub

If your tub is fiberglass, don't guess at what it's made of. Check the manufacturer's care instructions; if you can't find them, assume acrylic limits, which are the tightest.

On acrylic, skip solvents and abrasives, use a soft damp sponge, and rinse right away. The abrasive option for enamel or vitreous china applies only if the tub is actually one of those finishes.

Old, dried or set-in stains

Old epoxy paint is the hardest version of this job, and it may not come off completely. Start again with the gentle steps, since they're the safest way to see how much is still loose.

Once the paint has dried hard, no solvent route is safe for a tub, so you're left with light mechanical work. Scraping is meant for cured spray foam on surfaces, so keep any blade pressure light and never use steel wool or abrasive pads on a tub.

If the stain is still there after cleaning, it's realistic to accept some residue on acrylic rather than risk the finish. On enameled cast iron or vitreous china only, a stubborn mark can take a soft abrasive cleaner used sparingly, and a cast iron cleaner made for enamel marks is the other option.

Vinegar, baking soda, peroxide and more

Do home remedies work on epoxy on bathtubs?

Most household remedies won't lift cured epoxy from a tub, so stick with the gentle wash and the cleaner labeled for your tub material. None of the other remedies will lift cured epoxy from a tub, so there is no reason to try them. Stick with the gentle steps and the cleaner labeled for your tub material.

RemedyVerdictWhat to know
White vinegarSkipSkip vinegar; it doesn't lift cured epoxy from a tub, and it should stay away from cement grout. Keep it away from cement grout as well.
Baking sodaSkipBaking soda is a gentle cleanser for tubs, but it won't lift cured epoxy paint on its own. Use the mild steps instead.
Hydrogen peroxide (3%)SkipSkip peroxide; it doesn't lift cured paint. If you ever use it, choose the 3% drugstore solution. If you ever use it, choose the 3% drugstore solution and never the stronger hair-bleaching strength.
Dish soapSkipDish soap is for fabric spotting, so mild soap and warm water are the better pick on vitreous china. For routine cleaning on vitreous china, use mild soap and warm water.
Oxygen bleach (OxiClean)SkipSkip oxygen bleach; painted surfaces are off limits for it, so keep it off the tub. Leave it off the tub.
Rubbing alcoholAvoidKeep rubbing alcohol off acrylic, where it isn't safe; test a general-purpose cleaner first and work with a soft damp sponge.

What makes it worse

Mistakes to avoid

Don't use solvents on acrylic, cast iron or vitreous china

Solvents are off limits on all three surfaces, even when the paint looks stubborn. If the gentle steps don't lift it, stop and move on to the stronger options below instead.

Don't scrub acrylic with abrasives or aerosols

Abrasive cleansers damage acrylic, so keep them off the bath surface. Aerosol cleaning products should stay off acrylic too.

Don't use bleach or ammonia on airjet acrylic

Full-strength bleach can damage the surface of an airjet acrylic bath. Ammonia carries the same risk, so keep it off that surface too.

Don't use steel wool or scrub pads on cast iron

Steel wool, wire brushes and abrasive pads are off limits on cast iron. Use the cast iron cleaner for marks on enamel instead.

When to call a professional

If the paint won't lift, or the finish has gone dull or scratched, contact the manufacturer's customer service for repair rather than pressing harder. On cast iron, improper cleaning can void the warranty, so check its terms before trying anything heavy.

Questions

Can I remove epoxy paint from a bathtub once it has cured?

Cured epoxy is much harder to lift, and it may not come off completely. Work with the gentle steps first, and stop before you damage the finish, because scratching acrylic or using solvents to force it causes more harm than the paint.

Is vinegar safe for cleaning up epoxy drips?

No, vinegar belongs away from cement grout and natural stone, so use the gentle wash for drips instead. It also belongs away from cement grout and natural stone.

How do I clean epoxy off my hands?

Remove the resin with a waterless skin cleanser, then wash the hardener off with soap and warm water. Never use solvents on your skin, and change any epoxy-soaked clothes right away.

What if I don't know what my tub is made of?

Check the manufacturer's care instructions first. Without those instructions, follow acrylic limits, since acrylic is the most restrictive finish for this tub.

Can I use a cast iron cleaner on a fiberglass tub?

No, not unless you know the tub is enameled cast iron. Cast iron cleaners are meant for marks on enamel, and the abrasive option applies only to enameled cast iron or vitreous china.

Is epoxy in my eyes an emergency?

Yes, treat it as urgent. Flush your eyes with water for 15 minutes right away, and keep flushing for the full time even if the first few seconds feel better. Seek medical attention if discomfort persists after flushing.
