How to Clean a Fiberglass Shower

How to Clean a Fiberglass Shower

Fiberglass showers are popular because they're lightweight, durable and relatively easy to maintain. However, repeated exposure to soap, shampoo, body oils and water can leave fiberglass surfaces looking cloudy, dull or dirty.

Because fiberglass finishes can be scratched by overly aggressive cleaning tools, using the right cleaning method is especially important.

Why Do Fiberglass Showers Get Dirty?

Every shower leaves small amounts of residue behind. Over time, that residue can accumulate and become more noticeable.

Common sources of buildup include:

• Soap scum

• Shampoo and conditioner residue

• Body oils

• Dirt and grime

• Water-related residue

• Hair and other debris

• Everyday bathroom buildup

Corners, shelves, textured floors and areas around fixtures often collect buildup faster than smooth vertical surfaces.

What You'll Need

For routine fiberglass shower cleaning, gather:

• Natural Armor Tub & Tile Cleaner

• Soft sponge

• Microfiber cloth

• Soft-bristle cleaning brush

• Clean water

• Squeegee

• Clean microfiber towel

Avoid steel wool, aggressive scouring pads and other highly abrasive tools that may scratch or dull fiberglass.

Always check the shower manufacturer's care instructions and follow the product label before cleaning.

Step 1: Remove Items From the Shower

Remove shampoo bottles, soap, razors, shower mats and other items.

Pay particular attention to areas underneath bottles and containers, where water and soap residue frequently collect.

Step 2: Rinse the Fiberglass

Rinse the shower to remove loose hair, dirt and surface debris.

This allows the cleaner to work directly on the soap scum and grime remaining on the fiberglass.

Step 3: Apply Natural Armor Tub & Tile Cleaner

Apply Natural Armor Tub & Tile Cleaner according to the product label directions.

Focus on areas with visible soap scum, grime or everyday bathroom buildup.

Step 4: Allow the Cleaner to Work

Allow the cleaner the appropriate contact time specified on the label.

Giving the cleaner time to work can help loosen residue and reduce the amount of scrubbing needed.

Step 5: Gently Wipe the Fiberglass

Use a soft sponge or microfiber cloth to wipe the shower surfaces.

For textured areas or stubborn buildup, an appropriate soft-bristle brush can provide additional agitation.

Pay extra attention to:

• Shower corners

• Shelves and ledges

• Around faucets and fixtures

• The shower floor

• Around the drain

• Lower sections of shower walls

The goal is to loosen the buildup without damaging the fiberglass finish.

Step 6: Rinse Thoroughly

Rinse the shower thoroughly as directed to remove loosened soap scum, dirt, grime and cleaner.

Check the fiberglass after rinsing. Areas with heavier buildup may require another application.

Step 7: Dry the Shower

Use a squeegee or clean microfiber cloth to remove excess water.

Drying fiberglass after cleaning can help reduce water spots and the residue left behind when water evaporates.

How Do You Remove Heavy Soap Scum From Fiberglass?

Heavy soap scum may require more than one cleaning.

Apply Natural Armor Tub & Tile Cleaner according to the label directions, allow the recommended contact time and gently work the affected area with an appropriate non-abrasive sponge or soft brush.

If buildup remains, repeat the cleaning process rather than using increasingly abrasive tools.

What Should You Avoid When Cleaning Fiberglass?

Fiberglass surfaces can be damaged by improper cleaning techniques.

Generally, avoid:

• Steel wool

• Metal brushes

• Aggressive scouring pads

• Scrapers

• Highly abrasive cleaning powders

• Excessive scrubbing pressure

Always follow the fiberglass manufacturer's recommendations, particularly if the shower has a special coating or finish.

How to Keep a Fiberglass Shower Cleaner

Regular maintenance can reduce the need for heavy cleaning.

Try to:

• Rinse shower walls after use

• Squeegee or wipe away excess water

• Keep the bathroom properly ventilated

• Remove standing water

• Wipe up soap and shampoo residue

• Clean underneath bottles and containers

• Address visible soap scum promptly

• Clean the shower regularly
