Cleaning in Action:

Spray the non-abrasive cleanser around the perimeter of the tub or shower. Then use a very mild sponge and work the sponge in circular motions around the surface to coat and clean the area. Once you have covered the entire surface area with the non-abrasive cleanser, then you will need to use clean water to rinse off the cleaner. For tougher stains you could reapply the cleanser and let soak for a few minutes and then rinse.
