9 Household Products You Should Never Use on Your Car

Most household cleaners aren’t made for clear coat, tint film, touchscreens or seat belts, and a few can do lasting damage. These nine are the ones to keep away from your car, along with what’s at risk.

Safety first: Never mix cleaners. Mixing bleach with ammonia releases a toxic gas that can be deadly, according to MedlinePlus. A car is a small space, so keep the doors open for ventilation, wear gloves if the label says to, and follow the label. If someone is exposed, get to fresh air and call Poison Help at 1-800-222-1222, or 911 for an emergency.

1. Dish soap as your regular wash

Consumer Reports and AAA both warn that dish detergent can strip wax from your paint. One emergency wash won’t ruin anything, but regular use wears away the protection you’re relying on.

Use instead: Car wash soap. Here’s more on what dish soap really does to a car.

2. Bleach

This one has a real safety angle. Nissan’s owner’s manual says never to clean seat belts with bleach, dye or chemical solvents because they may severely weaken the webbing. Mazda’s manual also warns that bleach may weaken belts. A weak belt is not something you want to find out about in a crash.

Consumer Reports says never to use bleach products on leather or vinyl, and warns they can damage upholstery. Check labels too, because bleach can hide in other cleaners.

Use instead: A mild soap solution on belts, as your manual directs, then let them dry fully before they retract. Use interior cleaners made for the material on everything else.

3. Hydrogen peroxide

People reach for peroxide on stains and for disinfecting. Consumer Reports groups it with bleach as something to keep off leather, vinyl and upholstery. It can damage those surfaces and coatings.

Use instead: An upholstery or leather cleaner that’s labeled for cars. For stubborn stains, spot test somewhere hidden first.

4. Ammonia glass cleaner

Ammonia is a problem in three places.

• Touchscreens: Consumer Reports warns ammonia-based glass cleaner can harm anti-glare and anti-fingerprint coatings.
• Window tint film: Installers and tint brands warn that ammonia breaks down the film over time. Ceramic Pro’s aftercare page says it can cause fading, cracking and discoloration, and that using it will void the manufacturer’s warranty.
• Interior surfaces: Professional Carwashing & Detailing, a trade publication, also lists upholstery damage among the risks.

If you can’t tell whether your windows have film on them, treat them as if they do.

Use instead: An automotive or ammonia-free glass cleaner. Spray the cloth, not the glass. The car window guide covers the rest.

5. All-purpose household sprays on the dash, wheel and seats

Ford’s owner’s manuals are clear here. They warn that household cleaners and glass cleaners can damage the finish of the instrument panel, trim and cluster lens. On fabric seats, they can stain and discolor the material and affect its flame retardant properties.

There’s an airbag issue as well. Ford warns against chemical solvents or strong detergents on the steering wheel and instrument panel, and on seats with side airbags, because they can contaminate the airbag system.

Use instead: Follow your own manual. Ford recommends a clean, damp cloth for the dash, and the dashboard and vents guide covers safe methods.

6. Melamine sponges on paint

Magic Eraser style sponges feel soft, but Chemical Guys, which sells detailing products, compares melamine foam to ultra-fine sandpaper. It warns the foam can scratch clear coat and dull the shine, and says clear coat is only about as thick as a sheet of plastic wrap.

Use instead: For scuffs, use a polish or compound made for car paint, or ask a pro. Keep melamine sponges off screens and glossy trim too.

7. Scouring powders and scrub pads

Detail King, a detailing supplier, warns these are abrasive enough to scratch paint or plastic trim. The same goes for the rough side of a kitchen sponge. It may feel like it’s working, but it’s actually sanding the surface.

Use instead: Soft microfiber and a cleaner that lets the chemistry do the work. Give tough spots more dwell time, not more elbow grease.

8. Solvents like nail polish remover or paint thinner

These are tempting for tar, sap or paint transfer, but they’re a risky shortcut. Nissan’s manual says chemical solvents may severely weaken seat belt webbing, and Ford’s says they can contaminate airbag systems.

Use instead: A remover made for automotive paint, used as the label says. Keep flammable products away from heat and ventilate well.

9. Paper towels and old rags

They’re not cleaners, but they do damage all the same. The Manual warns against old towels, rags and T-shirts that can be abrasive on paint, and says paper towels can do harm too. Consumer Reports adds that paper towels can leave a trail of lint on interior surfaces.

Use instead: Clean microfiber cloths, with separate ones for paint, glass and wheels.

What about rubbing alcohol?

This one isn’t on the list because advice conflicts. Consumer Reports recommends isopropyl alcohol on a microfiber cloth for touchscreens and other hard surfaces. But Professional Carwashing & Detailing warns alcohol can ruin the urethane coating on leather seats, and Ceramic Pro says to keep it off tint film. So check your owner’s manual, keep it to hard surfaces, and spot test first.

What to keep on hand instead

You don’t need a shelf full of products. A car wash soap, an interior cleaner, an ammonia-free glass cleaner and a stack of microfiber will handle most jobs. The sprays and cleaners page explains what to look for, or you can search for ammonia-free glass cleaner directly. For the right order of work, use the interior cleaning guide.

If you’re dealing with a stain or surface you’re not sure about, a local detailer from the directory can save you from an expensive mistake.
