Light switches are often overlooked when cleaning, but they’re high-touch surfaces that accumulate dirt, grime, and oils over time. Those yellowish-brown stains and general dinginess can make your home feel less clean, even after you’ve scrubbed everything else. Instead of letting them detract from your otherwise tidy space, discover a simple and effective DIY solution that can make your light switches look fresh and new again.
This gentle homemade scrub uses a common household ingredient to tackle stubborn stains, offering an affordable way to refresh your switches with minimal effort.

What You’ll Need
- 1/4 cup Baking Soda
- 1-2 tablespoons Water
- Scrubbing sponge (the abrasive green side works best for this)
- Small bowl for mixing
- Clean damp cloth
- Dry cloth or paper towels
Why This DIY Can Be Useful
Baking soda is a mild abrasive that’s gentle enough not to scratch most surfaces but effective enough to lift grime and stains. When combined with a little water, it forms a paste that acts as a natural scouring agent. The abrasive side of a scrubbing sponge provides the necessary friction to dislodge stubborn dirt and oils that have built up on your light switches, leaving them looking much cleaner.
How to Make It
- In your small bowl, combine the 1/4 cup of baking soda with 1 tablespoon of water.
- Stir until a thick paste forms. If it’s too dry, add water a few drops at a time until you reach a spreadable consistency. It should be thick enough to cling to the sponge without being runny.
How to Use It
- IMPORTANT: Before you begin, turn off the power to the light switch at your circuit breaker. This is crucial for safety when cleaning electrical fixtures.
- Dip the abrasive side of your scrubbing sponge into the baking soda paste, picking up a generous amount.
- Gently but firmly scrub the surface of the dirty light switch, paying extra attention to the edges and any heavily stained areas. The mild abrasive action of the baking soda will start to lift the grime.
- Continue scrubbing until you see the stains begin to disappear.
- Once clean, use a clean, damp cloth to wipe away all the baking soda paste and loosened grime from the switch.
- Finally, use a dry cloth or paper towels to thoroughly dry the light switch and surrounding wall.
- Restore power at your circuit breaker.
What to Expect
You can expect your light switches to appear significantly cleaner, with most of the yellowish-brown grime and surface stains removed. The plastic should look brighter and refreshed. For very old or deeply ingrained discoloration within the plastic itself, the results may vary, but this method will certainly improve the appearance of surface dirt.
Helpful Tips
- For extra stubborn spots, let the paste sit on the switch for a few minutes before scrubbing.
- Always use gentle pressure to avoid damaging the finish of your light switch or the paint on your wall.
- Consider cleaning all your light switches at once for a consistent look throughout your home.
- Regular, light cleaning with a damp cloth can prevent heavy grime buildup in the future.
Important Notes / Safety
- Always turn off the power to the light switch at the circuit breaker before cleaning any electrical fixture to prevent electric shock.
- Avoid getting excessive amounts of water into the electrical components of the switch. The paste should be just damp enough to work, not soaking wet.
- Test a small, inconspicuous area first if you are concerned about the material of your light switch or surrounding paint.
- Ensure the switch is completely dry before turning the power back on.
