Things to Do When You Remove Stains From an Acrylic Bathtub

1. Test products

Always test products either underneath the tub or on the side. Some products can remove paint or causes damage.

3. Use neutral and homemade remedies

Most homemade remedies are safer for your family and the tub surface. Always try homemade remedies first before moving on to harsh chemical cleaners.

4. Clean all the stained crevices

Get into all the crevices as once the tub is free of dirt and stains, marks in the crevices are easily noticeable.

5. Use soft tools and pads

Abrasive cloths and scrubbers can damage the acrylic surface. Always use soft plastic cloths and tools.

Cleaners left on bathtubs too long can actually cause stains themselves. Always rinse the bathtub to remove all cleaner residues.
