Mildew is one of the most common bathroom problems. It thrives in damp, humid environments and often shows up as black or gray patches on tiles, grout, and shower curtains. Not only is mildew unsightly, but it can also lead to unpleasant odors and potential health issues if ignored. The good news is that with the right cleaning methods, you can easily learn how to get rid of mildew in shower and keep it from coming back.
In this guide, we’ll go over step-by-step methods to remove mildew from different shower surfaces, effective natural and commercial cleaners, prevention tips, recommended products, and answers to common questions.
What Causes Mildew in the Shower?
- Moisture: Showers are constantly exposed to water and humidity, creating a perfect breeding ground.
- Poor Ventilation: Bathrooms without fans or windows trap steam, encouraging mildew growth.
- Soap Scum Build-Up: Residue from soaps and shampoos provides organic matter mildew can feed on.
- Porous Surfaces: Grout, caulk, and shower curtains are especially prone to mildew growth.
How to Get Rid of Mildew in Shower: Step-by-Step
1. On Tile and Grout
- Mix equal parts white vinegar and water in a spray bottle.
- Spray directly on mildew patches and let sit for 10–15 minutes.
- Scrub with a stiff brush or old toothbrush.
- Rinse with warm water and dry the surface.
- For stubborn stains, make a paste of baking soda and water, scrub, and rinse.
2. On Shower Curtains and Liners
- Remove the curtain and place it in the washing machine.
- Add ½ cup vinegar or baking soda along with detergent.
- Wash on warm cycle and hang to air dry completely.
3. On Caulk and Sealant
- Apply a mixture of bleach and water (1:3 ratio) with a sponge or cotton ball.
- Let sit for 10–20 minutes.
- Scrub gently with a brush and rinse well.
- If mildew persists, replacing the caulk may be necessary.
4. On Glass Shower Doors
- Spray vinegar or a commercial mildew cleaner on the glass.
- Wipe with a non-abrasive sponge.
- Dry with a microfiber cloth to prevent streaks.
Natural Remedies for Mildew
- White Vinegar: Acidic and naturally antifungal.
- Baking Soda: Gentle abrasive that deodorizes.
- Lemon Juice: Natural bleaching effect for light stains.
- Hydrogen Peroxide: Kills mildew spores and brightens surfaces.
- Tea Tree Oil: Natural antifungal—mix 1 teaspoon with 1 cup water in a spray bottle.
Prevention Tips: Keeping Mildew Away
- Run an exhaust fan or open a window during and after showers.
- Wipe down walls and glass with a squeegee after each use.
- Keep the shower door or curtain open to let air circulate.
