Orange stains in the shower can be unsightly, stubborn, and sometimes even embarrassing when guests visit. These stains are usually caused by a combination of mineral deposits (like iron and calcium), soap scum, and bacteria—particularly Serratia marcescens, a pinkish-orange mold-like bacteria that thrives in damp environments.
If you’ve been scrubbing hard with little success, don’t worry—you’re not alone. Many homeowners struggle with these persistent stains. The good news? With the right techniques and cleaning solutions, you can restore your shower to its sparkling best.

Let’s dive in!
What Causes Orange Stains in the Shower?
Before tackling the stains, it helps to understand what’s causing them. The most common culprits are:
1. Iron & Hard Water Deposits
If your water has a high mineral content (hard water), iron and calcium can leave behind rust-colored stains. These deposits build up over time, especially on porous surfaces like grout and natural stone.
2. Serratia Marcescens (Pink Mold)
This bacteria thrives in moist, soapy environments and leaves behind pink or orange slimy residue. While not usually harmful, it can be difficult to remove if not treated properly.
3. Soap Scum & Body Oils
When soap mixes with minerals in water, it creates a filmy buildup that traps dirt and bacteria, leading to discoloration.
4. Old or Corroded Pipes
If your plumbing is aging, rust from pipes can seep into your water, leaving behind orange stains.
Best DIY Cleaning Solutions for Orange Shower Stains
You don’t always need harsh chemicals to remove orange stains. Here are some effective homemade remedies:
1. White Vinegar & Baking Soda Paste
Why it works: Vinegar dissolves mineral deposits, while baking soda acts as a gentle abrasive.
How to use:
- Mix baking soda with enough vinegar to form a thick paste.
- Apply to stained areas (grout, tiles, or shower doors).
- Let sit for 15–30 minutes.
- Scrub with a soft brush or sponge, then rinse.

2. Hydrogen Peroxide & Dish Soap
Why it works: Hydrogen peroxide kills bacteria and lifts stains, while dish soap cuts through grease.
How to use:
- Mix equal parts hydrogen peroxide (3%) and dish soap.
- Spray or dab onto stains.
- Let sit for 10–15 minutes.
- Scrub and rinse thoroughly.
3. Lemon Juice & Salt Scrub
Why it works: The citric acid in lemons breaks down minerals, and salt adds scrubbing power.
How to use:
- Cut a lemon in half, dip it in salt, and rub it over stains.
- Let sit for 10 minutes before rinsing.
4. Borax Paste for Grout Stains
Why it works: Borax is a natural disinfectant and mild abrasive.
How to use:
- Mix borax with water to form a paste.
- Apply to grout lines, let sit for 20 minutes, then scrub with a toothbrush.
Best Commercial Cleaners for Tough Stains
If DIY methods aren’t cutting it, these store-bought cleaners can help:

Preventing Orange Stains from Coming Back
Once your shower is clean, keep it that way with these tips:
✔ Wipe Down Surfaces After Each Use – A squeegee or microfiber cloth removes excess water and soap residue.
✔ Use a Water Softener – If hard water is the issue, a softener can reduce mineral buildup.
✔ Ventilate Your Bathroom – Run a fan or open a window to reduce humidity.
✔ Regular Deep Cleaning – Treat stains as soon as they appear to prevent buildup.
✔ Replace Old Pipes – If rust is the culprit, consider updating your plumbing.
