If your acrylic tub is heavily stained or dirty, consider filling the tub with hot water and vinegar. This will help loosen the dirt and grime before you clean the tub. Fill the tub with hot water and pour in 2 cups (470 mL) of vinegar. Let it sit for about 15 minutes and then drain the tub.
- The acid in the vinegar will help loosen the dirt without damaging the acrylic tub.
