Knowing how to clean a mirror properly makes a bigger difference than most people realize. Bathroom mirrors and decorative mirrors quickly collect toothpaste splatters, fingerprints, water spots, and dust, all of which can leave the glass looking dull or streaky. When mirrors are cleaned the right way, they reflect light better and instantly make a space feel brighter and more polished.
In this guide, you will learn how to clean a mirror step-by-step using simple tools and proven methods. These tips work for bathroom mirrors, vanity mirrors, and mirrors throughout your home, helping you achieve streak-free results every time.

Before you begin, gather the following supplies:
- Microfiber cloth
- Glass cleaning cloth
- Squeegee (optional, but helpful for large mirrors)

DIY glass cleaning solutions may be all you need to maintain your mirrors if you do not prefer an economical approach.
How to Clean a Mirror Step-by-Step
Step 1: Dust the Mirror First
Start by wiping the mirror with a dry microfiber cloth or a Swiffer duster. This removes dust and debris that can cause streaking or scratching once moisture is applied. When mirrors are dusted regularly, buildup is less likely to cling to the glass.
Step 2: Apply Cleaner and Clean the Mirror Surface
Spray your chosen glass cleaner onto a microfiber cloth rather than directly onto the mirror. This helps prevent liquid from seeping behind the glass and damaging the mirror backing.
If you are using a cleaner for the first time, test it on a small, hidden area. Then, wipe the mirror using gentle circular motions to remove fingerprints, toothpaste splatter, and smudges.
Plain water can be used for a quick clean, but it does not remove oils or residue as effectively as a proper glass cleaner.
Proper glass cleaning techniques help prevent streaks, scratches, and moisture damage, keeping your home’s mirrors clear, reflective, and in good condition for years.
Step 3: Remove Residue When You Clean a Mirror
Using a clean glass cleaning cloth, wipe away any remaining cleaner or moisture. Glass-specific cloths work especially well at this stage to help prevent streaks.
For larger mirrors, a squeegee can be useful. Pull the squeegee from top to bottom, then side to side, wiping the blade clean between passes.
Step 4: Buff the Mirror for a Streak-Free Finish
Finish by buffing the mirror with a dry cloth to remove any remaining water spots. Avoid pressing too hard. Always dry bathroom mirrors completely, especially after showers, to prevent moisture damage and rust along the edges.
How to Clean a Mirror With Hard Water Stains
Hard water stains require a little extra attention.
- Mix equal parts white vinegar and water in a small container.
- Dip a cloth into the solution and wring it out.
- Apply the mixture to the stained area.
- Let it sit for a few seconds.
- Wipe clean and repeat as needed until the stains are gone.
This vinegar solution can also help remove oily residue from mirrors.
Can You Clean a Mirror With Toothpaste?
Some people use toothpaste to clean mirrors, although this method is not recommended for regular cleaning. According to Cleanipedia, the process involves applying a small amount of toothpaste to a cloth, spreading it evenly on the mirror, letting the toothpaste sit, and then rinsing and buffing dry.
Use caution when using alternative mirror cleaning methods, as some toothpastes contain abrasives that may scratch mirror surfaces.
