How can I keep my fiberglass shower looking great?

Regular cleaning and maintenance is the key to keeping your fiberglass shower looking its best.

Be sure to follow the instructions on the cleaner and use a soft-bristled brush for scrubbing. 

Once finished, rinse the surface with water to remove any dish soap residue or dirt buildup. 

Additionally, applying a sealant such as wax or silicone caulk after each deep cleaning session is always a good idea to protect the surface from further damage.

With these tips, your fiberglass shower should stay clean and shiny!

Whether you opt for a natural cleaning solution or a commercial cleanser, plenty of options are available for keeping your shower clean and in top condition.
