If your shower door seal strip is looking dull and dirty, don’t despair. Here we’ll explore three easy methods to help get it sparkling clean in no time.

Materials needed for both methods:

  • Clean, dry cloth or sponge
  • A spray bottle

  • Mixing bowl

Method 1: Using Borax or Baking Soda

Step 1: Set up the Work Area

Before starting to clean the shower door seal strip, it is important to properly prepare the work area. This includes removing any excess grime and soap scum, as well as hard water deposits from the entire surface of the door seal.

Using a non-abrasive cloth or sponge is best when wiping away these deposits. Also, this will help keep any dust particles away from the cleaning process and ensure that all dirt and debris are removed before beginning.

Step 2: Prepare a Mixture

Using either Borax powder or baking soda, combine 2 tablespoons of mild liquid soap with 1 cup of the dry mixture in a bowl or container of some sort. Then add 1/2 cup of hot water and stir the mixture until it has fully dissolved into a thick paste-like consistency.

This mixture should be enough to cover an entire seal strip at once, so make sure you have enough on hand for larger projects.

Step 3: Seal Strip with Mixture

Once your mixture is ready, dip a soft toothbrush into it and scrub it on the rubber seal strip. Be sure to apply enough pressure while scrubbing so that all areas are adequately cleaned but not too much to not damage the seal strip itself.

After everything has been covered evenly with the mixture, let it sit for 15-20 minutes before moving on to the next step.

Step 4: Rinse off the Rest

After allowing sufficient time for the mixture to settle into all of its crevices, fill a large cup with warm water and gently pour it over the rubber seal strip on your door. It’ll help dislodge any particles left behind by your cleaning process and wash away any excess solution left after scrubbing.

Method 2: Using a Vinegar Solution

Step 1: Assemble the Mixture

When it comes to cleaning a glass shower door seal strip, one of the best solutions is to mix white vinegar and water in equal parts. This mixture can be created by using 1 cup of each liquid at a time.

For those looking for an extra boost of cleaning power, a teaspoon of castile soap or dish detergent can also be added to the solution. It is important to mix all of these liquids together before applying them to the seal.

Step 2: Apply the Mixture

Once the vinegar and water mixture has been thoroughly mixed together, it should then be sprayed onto the shower glass door seal. When applying this solution, it is important to ensure that all surfaces of the seal have been covered with an even layer of the mixture.

The solution should then be left on for 15-20 minutes so that it has time to work its magic and break down any dirt or grime. 

Step 3: Scrub Away Stains

Even after allowing the vinegar and water solution to settle, some stubborn stains may still remain on the seal strip that needs to be manually removed. To do this, a soft toothbrush should be used. Scrubbing each section again just before scrubbing to ensure it is properly wet and to increase effectiveness.

The seal strip cleaning process needs to run slowly and methodically to give equal attention to all parts. 

Step 4: Rinse off the Remaining Residue

After removing all of the stains from the seal strip, it is essential to rinse off any remaining residue. This means that you should rinse the shower door from both sides and the inside and outside edges of both seals.

To do this, you can slowly pour warm water over both sides of the seals until all remaining residue has been washed away thoroughly. Not only will this ensure that your shower remains clean and free from any potential bacteria build-up.

Method 3: Using Chlorine Bleach

Step 1: Make the Cleaning Solution

To make the solution, mix together 1/4 cup of liquid chlorine bleach with 3/4 cup of water in a spray bottle. Shake the bottle to ensure that the ingredients are well combined. Be sure to use gloves and eye protection when working with chlorine bleach, as it can cause skin and eye irritation.

Step 2: Apply the Solution

Once your cleaning solution is ready, you can begin cleaning your seal strip. Spray the seal liberally with your mixture and let it sit for 10-15 minutes to allow for maximum effect. This gives the chlorine bleach time to work its way into any dirt and grime on the seal strip so that it can be easily removed.

Step 3: Give It a Gentle Scrub

After 10-15 minutes have passed, it is time to scrub away any remaining residue. Use a soft brush and gently scrub away all the dirt and grime built up over time on your seal strip until it appears clean again.

Step 4: Rinse Everything Off

When you are finished scrubbing away all of the grime off your shower door seal strip, you need to rinse off all leftover residues. Fill up a large cup or bucket with fresh water and pour it over your seal strip several times until all traces of bleach are gone from its surface.

Why Do Shower Door Seals Get Dirty?

Why Do Shower Door Seals Get Dirty

Shower door seals are essential components of keeping water in your shower where it belongs. The problem is these seals can easily become dirty, grimy, and full of bacteria over time.

The following are some of the most common reasons:

Soap Scum Build-up: One of the primary reasons shower door seals get dirty is due to the buildup of soap scum. This occurs when soap, shampoo, body wash, and other products come into contact with the seal and create a film that can be difficult to remove over time. 

Hard Water Staining: Another reason shower door seals become dirty is hard water stains. Hard water contains minerals such as calcium carbonate that can leave a white residue on the surface of your shower doors after they have dried off from use.

Mold & Mildew Growth: If not properly sealed or dried off after each use, mold and mildew can grow quickly on shower door seals. Leading them to look unsightly and feel slimy or gritty when touched.

Wear & Tear: Due to constant contact with water or steam and regular exposure to hot air from showers and baths, rubber or vinyl shower door seals will naturally wear down over time. If you start noticing that your current seal looks wrinkled or worn out, it’s probably time for a replacement.

Abrasive Cleaners: Using abrasive cleaners such as steel wool pads or scouring pads may cause damage to the surface of your seal. While also introducing more dirt onto it due to small particles getting caught in between its crevices, making it dirty again quicker than usual.
