How Do You Get Dried Paint Off A Bathtub?

Acrylic bathtubs are a lovely addition to any bathroom, and the acrylic surface is mostly dirt and grime-resistant. However, acrylic scratches readily and is dissolved or destroyed by a wide range of solvents.

Acrylic tubs are one of the most challenging materials to remove paint since the damage is irreversible if you use the wrong cleaning solution.

1. Removing Fresh Paint From Acrylic Tub

  1. Wash the paint stains with hot water. If the paint spill is still wet, flushing it with hot water may remove most of it.
  2. If you have a detachable shower head, use it or a separate container to pour hot water over the spill to divert the drainage toward the drain.
  3. If you turn on the faucet and wait for it to fill up, the paint will mix with the water and stain the tub in other places. So, if you get blue paint on a white tub, you might get light blue stains, as an example.
  4. If there’s a lot of paint, it’s best to clean up as much as possible with paper towels before rinsing.
  5. Never use cold water when cleaning, soaking, or rinsing your tub. This can set dirt and fresh paint stains, whereas hot water prevents problems from forming on the tub’s surface.
  6. After wiping up the mess, you can move on to use a concentrated sudsy solution of laundry detergent.
  7. Fill the tub with warm or hot water and liquid laundry detergent. Unlike powdered laundry soaps, the liquid detergent doesn’t contain abrasives to scratch the acrylic tubs’ surface.
  8. If the stubborn paint stains have already dried, soak the spot in the solution for a few hours or overnight.
  9. Use a cleaning solution of a few drops of detergent per inch of water in the tub.
  10. Rub the stain with a washcloth or a soft sponge. You can drain the acrylic tub or leave the detergent solution in as you scrub the stain.

Ensure you never use abrasive things like steel wool or stiff-bristled brushes, as these will damage acrylic surfaces since they scratch easily.

2. Treat Paint Stain with Baking Soda and Vinegar

  1. Warm water should be used to wet the paint stain. Wet the area with warm to hot water after giving the stain a first work-over.
  2. The goal is to keep the area moist so that the paint doesn’t dry on the tub’s surface. Allow time for the water to warm the acrylic by running it over the entire tub bottom. You can leave water over the paint for a few hours, so it doesn’t dry.
  3. Sprinkle baking soda over the affected area after wetting the tub floor.
  4. The wet baking soda will form a paste and loosen the stain. Allow 5-10 minutes for the paste to rest on the stain before applying the vinegar.
  5. Fill a spray bottle halfway with vinegar and spray the baking soda paste. The vinegar activates the baking soda, which results in a frothy layer in your tub.
  6. Allow 5-10 minutes for the combination to work its way through any accumulated filth or discoloration.
  7. If you prefer, soak a sponge in vinegar and apply it directly to the affected area. The vinegar paste and baking soda will react as you scrub, making physical cleaning more effective.
  8. Scrub the area with a washcloth or sponge. Make enough time for the vinegar and baking soda mixture to work on the stain. If necessary, repeat the procedure to make sure no remnants of the paint stain remain.

Will Paint Thinner Hurt A Bathtub?

Only use non-abrasive cleansers because acrylic is prone to scratching and may react poorly when exposed to certain chemicals in cleaning agents.

Ordinary cleaning chemicals like Comet and Ajax, designed for porcelain and other materials, are too harsh for an acrylic tub.

Look for non-acetate cleansers, as acetates can eat away at the gel coat on an acrylic surface. Likewise, paint thinners have the same abrasive impact on the bathtub as an abrasive scrub pad or steel wool.

Mild all-purpose cleansers such as OxyClean, Bathtub & Shower Cleaner, and Kaboom have been shown to clean acrylic bathtubs effectively without harming a clear coat finish.

Acrylic and other plastic-based materials are less durable than porcelain. In addition, you must avoid using harsh chemicals and solvents, or the tub’s protective covering may be damaged.

So, while you can remove paint from a stained surface in a porcelain tub using a paint stripper, you won’t be able to do the same with an acrylic or fiberglass tub.

Fortunately, removing epoxy paint and restoring your bathtub to its original fiberglass surface is extremely simple.
