When choosing commercial cleaners, make sure it’s safe for your fiberglass tub or shower. Abrasive cleaning agents, like Ajax or bleach, can cause scratches or damage to the tub or shower.

Here are some of the cleaning agents you can use if homemade ones are a tedious task.

Make sure to read instructions before usage and always wear rubber gloves to avoid skin irritations or burns from using these cleaning agents.

Maintenance and Don’ts With Your Fiberglass Tub and Shower

To prevent a massive build-up of scum, molds, mildew, and hard water stains on your fiberglass tub and shower, you must have weekly upkeep to prevent it from looking dirty.

First, clean your bathtub with one of the methods above. Then use the disinfectant listed below as your weekly upkeep to maintain the cleanliness at all times.

• You can use hydrogen peroxide as your disinfectant. Just put 100mL of 3% hydrogen peroxide in a spray bottle. Make sure to use rubber gloves before putting it in a spray bottle. Spray it into the tub and wait for 30 minutes before rinsing with water.
• You can also use baking soda alone. Just sprinkle it and dampen it before leaving it overnight. Rinse it in the morning with hot water. And your tub or shower is all clean!
• Don’t use hydrogen peroxide on any fiberglass tub because the color will fade away.

Conclusion
