Cleaning an acrylic shower enclosure is completely different than cleaning a fiberglass enclosure or a ceramic tile enclosure. Cleaning these enclosures requires a bit more care with cleaning products.
Acrylic shower enclosures scratch easily and are more to hard water stains. Consider a water softener to alleviate this problem if you live in a hard water area. Be aggressive in keeping the enclosure dry, so wipe it down with a towel after each use to keep it looking new.
Cleaning Do's and Don'ts
The most important guideline is not to use an acid based cleanser, such as Lime Away or KLR. The acid will damage the acrylic. Also do not use vinegar. Don't use scouring powder or steel wool or ammonia.
Use a gentle all purpose cleaner that doesn't contain any of the above ingredients. Read the label of your favorite household cleaner to double check. There are several cleaners on the market specifically for this purpose. If you have stubborn stains, try scouring them with baking soda and a wet rag. Always rinse your enclosure and wipe it dry after cleaning.
