The Effortless Way to Clean Gross White Plastic Cutting Boards (My Ma’s Trick)

Here’s the trick my ma swears by (and now I do too) for getting those gross, stained, smelly white plastic cutting boards back to “almost new” — without crazy scrubbing or harsh chemicals all the time.

It’s super simple, cheap, and uses stuff you probably already have at home.

🧼 What You’ll Need

• Baking soda

• Hydrogen peroxide (the regular 3% kind from the pharmacy)

• A few drops of dish soap

• Optional:

  • Lemon

  • Coarse salt

  • Diluted bleach (for a once-in-a-while deep disinfect)

🪄 Step 1 – Start With a Quick Wash

Before the magic part, always do this:

• Wash the board with hot water + dish soap to remove surface grease and food.

• Rinse well.

• Shake off excess water – it doesn’t have to be bone dry, just not dripping.

✨ Step 2 – Ma’s Magic Paste (No Scrubbing Workout Needed)

This is the real trick.

1. Lay the cutting board flat in the sink.

2. Sprinkle a good layer of baking soda over the stained or smelly areas.

3. Drizzle hydrogen peroxide on top of the baking soda until it looks like a thick, foamy paste.

4. Add 2–3 drops of dish soap and gently spread everything around with your fingers or a sponge.

Now just leave it there for 10–20 minutes.
The combo of baking soda (mild abrasive + deodorizer) and hydrogen peroxide (gentle bleach + sanitizer) does the hard work for you.

🧽 Step 3 – Light Scrub & Rinse

After it has sat:

• Use a scrub brush or sponge to lightly scrub the board.

• Pay attention to knife grooves and edges.

• Rinse very well with hot water.

You’ll usually see:

• Stains faded or gone

• Smells massively reduced or completely gone

• The board looking whiter and much “cleaner” overall

🍋 Extra: For Deep Stains & Strong Odors

If your board has old turmeric, beet, garlic, onion smells:

Lemon + Salt Scrub

• Sprinkle coarse salt over the board.

• Cut a lemon in half and use the cut side like a scrubber, rubbing salt around in circles.

• Let it sit 5–10 minutes, then rinse.

This:

• Deodorizes

• Gently bleaches

• Leaves a fresh smell

You can do lemon + salt first, then Ma’s baking soda + peroxide trick for extra nasty boards.

🧴 Once in a While: Deep Disinfect (Plastic Boards Only)

For plastic cutting boards used for raw meat, my ma does this occasionally:

• Mix: about 1 tablespoon bleach in 1 liter (4 cups) of water.

• Pour enough over the board to cover the surface.

• Let sit 2–5 minutes only.

• Rinse VERY well with lots of water.

• Let it air dry standing up.

⚠️ Important:

• Never mix bleach with vinegar, ammonia, or other cleaners.

• Use in a well-ventilated area.

• This is only for plastic, not wood.

🌞 Step 4 – Dry the Right Way

• Stand the board upright or hang it so air circulates around it.

• Make sure it’s fully dry before storing — moisture trapped in knife grooves = bacteria + smells.

Bonus: if you can put it near indirect sunlight, that also helps keep it fresh.

🧠 Maintenance Tips So It Stays Clean Longer

• Have separate boards:

  • One for raw meat

  • One for veggies/bread

• Replace boards that are deeply scarred with heavy grooves – those cuts hold bacteria and stains.

• If dishwasher-safe, an occasional run on the top rack helps sanitize (but Ma’s trick still wins for stains and smells).
