Toothpaste is not just for cleaning teeth — it has surprising applications around the house and in personal care, according to a Vietnamese lifestyle article. The piece outlines three unusual uses of toothpaste, claiming they can simplify everyday tasks. (Tap Chí Đời Sống) (tapchinuocmy.com)
Below is an expanded version with rationale, caveats, and whether science supports these hacks.
The article suggests applying a small amount of white or non-gel toothpaste onto rusty spots (on screws, hinges, or tools). Rub gently with a soft cloth or toothbrush, then rinse and dry. The mild abrasives in toothpaste can help scrub away surface rust without harsh chemicals.
For tarnished silver or dull jewelry pieces, toothpaste is said to restore shine. The method: apply a thin layer of plain white toothpaste, gently rub with a soft cloth, then rinse off. The toothpaste’s polishing agents help remove oxidation and slick grime.
If your eyeglasses or smartphone screen is cloudy or has light scratches, apply a pea-size bit of non-gel toothpaste, rub gently in circular motions, and then rinse. The abrasives can buff minor scratches and restore clarity (for less severe damage).
Toothpaste typically contains micro-abrasives (silica or calcium carbonate) which can gently scour off oxidation, grime, or surface deposits.
It also contains surfactants and mild cleaning agents that help lift dirt and oils.
However, the abrasives make this a mild polishing action — too much pressure or repeated use can scratch soft metals, coated surfaces, or delicate glass.
When to be cautious:
Don’t use toothpaste on coated lenses (antireflective, UV, or oleophobic coatings). These coatings might be damaged by abrasion.
Avoid colored gel, whitening, or gritty toothpaste formulas — these are harsher. Use plain white paste without extra particles.
On jewelry, be careful with gemstones (like opal, turquoise, pearls) that are softer or porous — toothpaste can damage them.
Always test a small hidden spot first before applying broadly.
Several cleaning guides (e.g. Good Housekeeping, Reader’s Digest) mention toothpaste as a handy hack for removing scratches or stains on glass, chrome, or white sneakers.
Optometry and lens care sources often warn that abrasive compounds risk damaging delicate optical coatings — hence, most professionals recommend lens cleaners designed for glasses over DIY abrasives.
In metal care forums, users often use toothpaste for small spot polishing, but they emphasize doing it gently and finishing with a soft cloth and protective polish or wax.
Use a pea-sized amount of plain white toothpaste; dilute with a little water if needed.
Use a soft microfiber or cotton cloth, not a rough sponge or abrasive pad.
Rub gently in small circular motions — don’t scrub hard.
After cleaning, rinse thoroughly and dry the surface to prevent residue.
For precious items or devices, consider consulting a professional rather than risk damage.
After spending a few days at my mother-in-law’s country house, I realized I couldn’t go through with the wedding, making the difficult decision to call it off.
