How to Use Toothpaste for Cleaning | DIY Household Tricks

For the full breakdown, see our best Cleaning Toothpaste guide.

That tube of toothpaste in your bathroom cabinet can handle more than your morning routine. For small household tasks like lifting crayon marks off walls or brightening tarnished fixtures, a dab of plain white toothpaste often outperforms a trip to the store. The trick is knowing which surfaces welcome it, which ones it will ruin, and how to use it without leaving a sticky mess behind.

Which Toothpaste Works Best for Cleaning?

Reach for plain white, non-gel toothpaste when you clean. Gel, charcoal, whitening, and colored varieties contain dyes and abrasives that can discolor or damage the surfaces you’re trying to fix.

You also need the right tools. A soft cloth, microfiber cloth, sponge, or old toothbrush gives you controlled pressure. Hard-bristled brushes or rough scrubbers will scratch finishes that the toothpaste itself might not.

What Can You Clean With Toothpaste?

Toothpaste shines brightest on small, specific jobs where its mild abrasiveness lifts grime without harsh chemicals. Here are the surfaces where it consistently delivers:

• Copper and tarnished metal: rub gently in circles, then rinse with warm water and dry completely.
• Chrome faucets and bathroom fixtures: scrub with a sponge, let it sit briefly, then rinse and buff dry.
• Silver jewelry: apply with a soft toothbrush, rinse, and dry for a fast shine.
• Bathroom sinks and soap scum: work it into the residue, let it sit, then rinse thoroughly.
• Crayon or marker marks on walls: dab a small amount on the mark, rub with a damp cloth, and wipe dry.
• Shower doors and mirrors: a thin layer removes hard-water film; rinse well to avoid haze.
• Shoe soles and leather sneakers: scrub gently, then wipe with a damp cloth.

Each of these jobs follows the same basic rhythm: apply a pea-sized amount, rub gently, rinse, and dry.

How to Apply Toothpaste for Best Results

The technique matters as much as the toothpaste itself. Start with a small amount — a pea-sized dab covers most jobs — on a damp microfiber cloth. Work in circular motions with light pressure, letting the paste do the lifting rather than your elbow. Once the stain or tarnish lifts, wipe the area with a clean damp cloth and dry it completely so no film or residue remains.

Step-by-step for the most common job, tarnished metal:

1. Squeeze a pea-sized amount of white toothpaste onto a soft cloth or old toothbrush.
2. Rub gently in circular motions over the tarnished area for 30–60 seconds.
3. Rinse with warm water and dry completely with a clean cloth.

The circle-motion approach also works for scuffs on hard surfaces, soap scum rings, and marker marks. For tougher buildup, let the paste sit for two to three minutes before wiping — the mild abrasives soften the grime so it releases more easily.

Where Toothpaste Can Damage Surfaces

Toothpaste is abrasive, and that strength cuts both ways. It can dull polished finishes, scratch coated metals, and strip paint from delicate surfaces. Always test on an inconspicuous spot first — a corner, underside, or hidden seam — before committing the whole surface to a paste treatment. Dark or colored surfaces show scratches faster than light ones; proceed with extra care there.

Skip toothpaste entirely on stone countertops, painted walls beyond the occasional crayon mark, uncoated aluminum, and screens or electronics. While one source mentions phone screens, no reputable manufacturer approves toothpaste for electronics, and the risk of scratching the oleophobic coating is real. Stick to the metal fixtures, sinks, and shoes listed above.

Rinsing is the step most people skip, and it’s the one that separates a clean finish from a hazy one. Toothpaste residue hardens into a film that catches dust and dulls shine. A final wipe with a damp cloth followed by a dry buff keeps the surface looking freshly done.
