What Makes a Good Cleaner for Fiberglass Tub

If you want to make sure you get our hands on the best cleaner for fiberglass bathtub, see if it includes the following qualities:


One of the most important things to consider while purchasing a tub cleaner is how powerful it is. Since you are using a fiberglass tub, you cannot use anything that is particularly harsh on it to remove stains and grime buildup. That will damage the fiberglass and ruin the look and feel of your tub.

Therefore, you have to invest in a tub cleaner that powerfully and effectively removes all stains, grime, and buildup, without damaging the material of your tub. Bonus points if the cleaner provides protection against future buildup, and adds some extra shine.


Products with extra fragrance can be heavily irritating to children and elderly people. It is also a sign that the product has many more chemical ingredients in it than it should typically. Fragrance can also be irritating to the skin and cause eczema, rashes, etc.

Always opt for a cleaner that does not have a heavy aroma. If you feel like a soft scent would help lift the mood, use essential oils instead.


You are using the tub cleaner along with water and then draining it. So make sure that the product you will buy is environment-friendly, and does not contain any toxic materials.
