Q&A for How to Clean Fiberglass Bathroom Surfaces

You can use vinegar to remove hard water stains from your fiberglass tub. First, spray the stains with vinegar and allow the stains to soak for 10 minutes. Then, you can place paper towels over the stains and spray the paper towels with vinegar. Allow this to sit for another 10 minutes or so. Remove the paper towels and sprinkle baking soda over the vinegar. You may need to re-apply the vinegar over the baking soda. Use a soft sponge with the vinegar and baking soda mixture to scrub away the stains.

If your fiberglass bathtub has any built-up soap scum, you can create a baking soda paste by mixing baking soda and water. Let the paste sit on the tub for anywhere from 20 minutes to a couple of hours, depending on how stained the tub it. Scrub the tub with a soft sponge until it is clean. For regular maintenance of your fiberglass tub, you should apply vinegar and wipe it with a soft rag or soft sponge a couple of times a week.

When cleaning fiberglass, you want to be sure to avoid abrasive scouring pads or products. For general cleaning, you should use a non-abrasive cleaner, such as a mild dish detergent, laundry detergent, or a household all-purpose cleaner.

Best way is to follow the steps with the polishing compound and finish with clear (white) automotive wax. Be careful with wax if using on floor of tub or shower, it's like ice skating. Best way to use on floor is if you will be always using a mat, or are applying non slip decals. For sides use 2 layers wax, but only one for floor (if at all). Safety is more important than beauty, but in case of moving out, or selling, one layer on floor of tub will be more impressive. Just explain its a slippery tub.
