Egg spills, marble and more: 7 things you should never clean with DIY vinegar and soap solution at home

Vinegar and liquid soap are often treated as an all-purpose cleaning duo, but combining household ingredients without checking the surface first can do more harm than good. Vinegar is acidic, while soaps can react poorly with acidic solutions. Some materials can be etched, dulled or damaged by vinegar, while others simply require a different cleaning method.

Why you shouldn't automatically mix vinegar and soap

Vinegar is acidic, while traditional soap is alkaline. When mixed, the acid can react with the soap and reduce some of its cleaning effectiveness. So while the combination may still appear to work for certain household jobs, mixing the two doesn't automatically create a stronger cleaner. For housekeeping, it's often better to use the right product for the specific type of dirt and surface.

The most important rule is simple: don't use vinegar everywhere just because it's a common household cleaner. Never mix vinegar with bleach or products containing bleach. This can release dangerous chlorine gas. And before using vinegar on a surface, particularly stone, wood, metal finishes or appliances, check the manufacturer's cleaning recommendations. A cheap cleaning ingredient isn't necessarily a universal cleaning solution. Knowing where not to use vinegar can be just as useful as knowing where it works.


Here are seven things you should not clean with vinegar and soap, and what to use instead.

Marble and natural stone countertops

Don't use vinegar on marble, limestone, travertine or other acid-sensitive natural stones. Vinegar's acidity can react with the minerals in these surfaces, potentially causing dull spots, etching and loss of shine. Adding soap doesn't make vinegar safer for stone.

Use instead: A pH-neutral stone cleaner or mild dish soap diluted with water, depending on the manufacturer's care instructions.

Granite with a protective seal

Granite is more resistant than marble, but that doesn't mean vinegar is automatically safe. Repeated exposure to acidic cleaners can potentially affect the sealant protecting the surface. Dish soap and warm water are generally a safer everyday option.

Use instead: A cleaner specifically labelled as safe for sealed natural stone.

Wood furniture and wooden floors

Wood needs more careful treatment than many hard, non-porous surfaces. Vinegar can affect certain finishes, while excessive moisture can seep into unfinished or damaged wood. A vinegar-and-soap mixture is therefore not a universal wood cleaner.

Use instead: A slightly damp microfiber cloth and a wood-safe cleaner recommended for your particular finish.

Electronics and screens

Your television, laptop, phone and other electronic screens aren't good candidates for homemade vinegar-and-soap solutions. Liquids can damage electronic components if they enter openings, while unsuitable cleaning products can affect screen coatings.

Use instead: Follow the manufacturer's cleaning instructions. For many screens, a clean, dry microfiber cloth is the safest starting point.

Car interiors and leather

Leather and other specialised car-interior materials can be sensitive to household cleaning mixtures. Vinegar is acidic and isn't a good default choice for leather. Dish soap can also strip oils or leave residue if used incorrectly.

Use instead: A cleaner specifically formulated for automotive leather or the particular material you're cleaning.

Egg spills

This one may sound surprising, but vinegar isn't the best choice for cleaning raw egg from a surface. Acid can cause proteins in egg to coagulate, potentially making the mess harder to remove.

Use instead: Use cold or cool water with a small amount of dish soap to lift the egg, then wipe the surface clean. Later, to make ensure there's no odour, you can place a small plate of baking soda.

Certain stone tiles and grout

Vinegar shouldn't be treated as a universal bathroom cleaner. Acid-sensitive stone tiles can be damaged by acidic products. Even where the tile itself is resistant, grout and sealants may have different care requirements.

Use instead: Choose a cleaner specifically designed for the type of tile and grout in your bathroom.
