Cleaning Fiberglass Bathtubs

The factors mentioned are very integral in cleaning up your fiberglass bathtub. So, please pay heed to them and clean accordingly.

Choose Cleaning Solutions Wisely

While there are lots of chemical solutions to do your job, the best solutions should be non-abrasive and harsh free.

Abrasive solutions like polishing powders containing tin or aluminum oxide might give a polished shine to the bottoms but will lead to the surface being damaged and may result in scuffing and dulling very rapidly.

It also involves roughening of the bases and is suggested to be avoided. As their alternative, non-abrasive solutions can be used like baking soda which is the most effective option, followed by laundry soaps, dishwashers, and detergents.

Such solutions work getting the dirt off the bottoms which has been deposited over a prolonged time.

Preparing The Cleanser

For a moderate amount of dirt to be cleaned, a bucket of warm water with a few drops of the solution you're using will be enough. But if you think the grim is too hard to get rid of, you can add around 5-6 drops more to it.

The ratio for the solution and water should be about 1:3 respectively. Water should be lukewarm, and the detergent/baking soda/dishwasher should be added dropwise and stirred well.

Application Of The Cleanser

After the solvent has been prepared, use a soft sponge to dab into the solution and apply on the bottom, scrubbing on the yellow stains and dirt dents.

Hard sponges and scrapers should be avoided as they might seem quite harsh on the fiberglass. Polyester sponges serve best for scrubbing scum off the dented squared bottoms.

Washing Off

The cleansing solution should be set on the fiberglass for as long as an hour or two for the filth to come off. After the said period, use lukewarm water to wash the bottom properly and rinse thoroughly. The surface needs to be dried completely using a towel or a cloth to avoid microbes growing on wet areas.

Maintenance Over A Long Time

The fiberglass bathtubs need cleaning and taking care throughout the week for preventing excess accumulation of scum daily. Vinegar can be sprayed on the fiberglass twice a week to avoid lousy odor and frequent staining.

Use polishing or waxing materials once a year to improve the longevity of the fiberglass. Always pat the fiberglass dry after washing and cleaning once a week. This decreases the chances of the fiberglass to get stained.
