Cleaning with Toothpaste — What Actually Works | Simply Maid

You use it twice a day to clean your teeth — but that humble tube of toothpaste on your bathroom shelf doubles as a surprisingly effective household cleaner. The catch? It works brilliantly on some surfaces and can genuinely damage others. If you've ever wondered whether those viral "cleaning with toothpaste" tips are actually worth trying, here's the honest answer.

**Quick Answer:** Regular white toothpaste contains mild abrasives like calcium carbonate and hydrated silica that gently scour away grime. It works well on hard surfaces like ceramic sinks, stainless steel, and scuffed walls. But skip it on phone screens and leather — the same abrasives that clean your teeth can strip protective coatings and cause irreversible damage.

Why Toothpaste Works as a Cleaner

It's not magic — it's chemistry. And understanding the science helps you use toothpaste safely (and know when to skip it entirely).

Toothpaste gets its cleaning power from three ingredients:

**Mild abrasives** — most commonly hydrated silica and calcium carbonate — physically scrub away stains and buildup. According to [research published in the journal *Dentistry*](https://pmc.ncbi.nlm.nih.gov/articles/PMC10047781/), these particles form tiny polyhedral clusters that work like very fine sandpaper, gently wearing away surface deposits without gouging the material underneath.

**Surfactants** (usually sodium lauryl sulfate) break down grease and oil, similar to dish soap. This is why toothpaste cuts through fingerprints and kitchen grime so effectively.

**Fluoride and flavouring agents** don't contribute to cleaning power, but they're harmless on household surfaces in the small amounts you'll use.

Here's the important bit: your tooth enamel rates about 5 on the Mohs hardness scale — harder than steel. So when someone says "if toothpaste is safe for your teeth, it's safe for anything," they've got it backwards. Your teeth are tougher than most surfaces in your home. Softer materials like phone screen coatings (Mohs 2–3) or leather finishes can absolutely be scratched or stripped by those same abrasives.

Which Toothpaste Should You Use?

Not all toothpaste cleans equally. Here's what to reach for — and what to leave in the drawer.

**Use this:** Plain white, non-gel toothpaste. In Australia, that means brands like **Colgate Cavity Protection** or **Macleans Protect** — both available at Coles, Woolworths, and Aldi. These contain standard-strength abrasives without extras that could cause problems.

**Avoid this:**

**Gel toothpaste** — lacks the abrasive particles that do the actual cleaning. Coloured gels can also leave dye residue on light surfaces.
**Whitening toothpaste** — scores higher on the RDA (Relative Dentin Abrasivity) scale, meaning more aggressive abrasives. As [teeth.org.au explains](https://teeth.org.au/toothpaste-abrasives), the type and concentration of abrasive particles directly affects how much material gets removed — and on delicate surfaces, that's a problem.
**Charcoal or specialty toothpaste** — unpredictable abrasive levels and may contain dyes or oils that leave residue.

**How much to use:** A pea-sized amount handles most small jobs. For a full sink, use about a 2 cm strip.

5 Surfaces You Can Safely Clean with Toothpaste

Ceramic and Porcelain Sinks

This is toothpaste's home ground — literally. Ceramic and porcelain rate 6–7 on the Mohs scale, well above standard toothpaste abrasives. Squeeze two or three small blobs around the basin, spread with a dry scrubbing pad, then dampen and scrub in circular motions. Rinse thoroughly.

The surfactants cut through soap scum while the abrasives tackle water marks and light staining. You'll notice the difference immediately.

**Tip:** This works equally well on porcelain bathtubs. For a deeper bathroom clean, see our guide to [cleaning and sanitising a bathtub](/cleaning-101/bathroom/how-to-clean-and-sanitise-a-bathtub).

Stainless Steel Fixtures and Appliances

Stainless steel (Mohs 5.5–6.5) handles toothpaste abrasives without trouble. Dab a pea-sized amount onto a damp microfibre cloth and buff taps, kitchen sinks, or [stainless steel appliance fronts](/cleaning-101/kitchen/a-cleaning-guide-to-sparkling-stainless-steel-appliances) in smooth, even strokes. The result is a streak-free shine without chemical sprays.

**Important:** Always rub in the direction of the steel's grain — the faint lines you can see on the surface. Cross-grain rubbing can leave fine scratches that catch the light.

Scuff Marks on Painted Walls

Kids, furniture legs, shoe soles — painted walls collect scuff marks from every angle. Dab a small amount of white toothpaste onto a damp microfibre cloth and gently rub the mark in a circular motion. The mild abrasive lifts the scuff without stripping the paint beneath.

**⚠️ Safety note:** This works best on matte and eggshell finishes. On glossy or semi-gloss paint, toothpaste abrasives can dull the sheen permanently. Always test on a small, hidden patch first.

White Plastic Outdoor Furniture

If your white plastic chairs have gone yellow from UV exposure, toothpaste can help. Mix a tablespoon of paste into two cups of warm water, dip a soft-bristled brush, and scrub the surface. The abrasive gently removes the oxidised outer layer, revealing brighter plastic underneath. Rinse and towel dry.

**Tip:** Stick to white or light-coloured plastic. On darker colours, the abrasive may lighten the surface unevenly.

Chrome Fixtures

Chrome-plated taps, towel rails, and showerheads develop water spots and light tarnish over time. A tiny dab of toothpaste on a soft cloth, buffed gently and rinsed clean, restores the mirror shine. For ongoing chrome maintenance, see our guide to [keeping chrome bathroom fittings clean and rust-free](/cleaning-101/bathroom/keep-your-chrome-bathroom-fittings-clean-and-rust-free).

What You Should Never Clean with Toothpaste

This is where most "cleaning with toothpaste" articles get it wrong. They list every possible use without warning you about the ones that backfire.

Phone and Tablet Screens

This is the single most important warning in this article. Despite viral tips suggesting otherwise, **toothpaste should never touch your phone or tablet screen**.

Modern screens have a thin oleophobic (oil-repelling) coating that reduces fingerprint smudging and improves touch sensitivity. [Independent tech analysis confirms](https://www.redwolf.io/post/myth-or-science-removing-phone-scratches-with-toothpaste) that toothpaste abrasives strip this coating entirely — resulting in more smudging, reduced visibility in sunlight, and a rougher screen texture.

[Screen repair specialists note](https://pelacase.com/blogs/news/how-to-remove-scratches-from-phone-touch-screen) that once the oleophobic coating is gone, it cannot be restored without professional screen replacement.

**⚠️ Safety note:** If your phone screen has minor scratches, take it to a professional repair service or use a screen-specific product. Toothpaste will make the problem worse, not better.

Leather

You might have seen this tip circulating online — a dab of toothpaste to buff out leather scuffs. The problem is that even mild abrasives can strip natural oils and conditioner from leather, leading to drying, cracking, and discolouration over time. Use a dedicated leather cleaner instead. Australian options like **Oakwood Leather Cleaner** (available at Bunnings and Coles) are purpose-made for the job.

Lacquered or Glossy Finished Surfaces

Any surface with a clear-coat, lacquer, or high-gloss finish is at risk. This includes lacquered timber furniture, engineered stone benchtops (like Caesarstone), and coated metals. The abrasive in toothpaste can dull the finish, leaving permanent haze marks that no amount of buffing will remove.

Frequently Asked Questions

Q: Can toothpaste damage my phone screen?

Yes. Toothpaste abrasives strip the oleophobic coating on modern screens, increasing fingerprint smudging and reducing visibility in sunlight. The damage is irreversible without professional screen replacement. Use a screen-specific cleaning product instead.

Q: Does it have to be white toothpaste? Why not gel?

Gel toothpaste typically lacks the abrasive particles that do the actual cleaning. It may also contain coloured dyes that leave residue on surfaces. Plain white, non-gel toothpaste is the only type suitable for household cleaning.

Q: Is cleaning with toothpaste better than using proper cleaning products?

Not for regular cleaning. Toothpaste is a handy substitute when you don't have the right product on hand, but purpose-made cleaners are more effective and more economical for routine use. Think of it as a great pinch-hitter — reliable in a moment, but not your everyday starter.

Q: Will toothpaste scratch stainless steel?

Standard non-gel white toothpaste is generally safe for stainless steel. The key is to always rub in the direction of the grain. Avoid whitening toothpaste, which has a higher abrasive load and can leave fine scratches.

Q: Can I use whitening toothpaste for household cleaning?

Use it with caution. Whitening formulas score higher on the RDA (Relative Dentin Abrasivity) scale, meaning stronger abrasives. They may also contain bleaching agents that lighten coloured surfaces. For household cleaning, plain white non-whitening toothpaste is the safer choice.
