White vinegar: what it removes and where never to use it
Distilled white vinegar, about 5% acetic acid.
- pH
- 2.4–2.6
- Safe on
- 0 materials
- Never on
- 1 materials
- UK name
- distilled white (spirit) vinegar
01 How to use it
Usually diluted: 1 tbsp (15 ml) with 1 tbsp dish soap in 2 cups (480 ml) of cool water for tannin stains; 1:1 with water for deodorant marks and odours.
- Never mix with chlorine bleach (chlorine gas).
- It etches marble, limestone and travertine.
How it works
Acids dissolve minerals (limescale, rust, aluminium salts) and neutralise alkaline residues. They also dissolve calcium carbonate, which is why they etch marble and erode grout.
On a label
On an ingredient list, white vinegar shows up as acetic acid.
White vinegar is ruled out on marble. Avoid routine home use on granite and grout. The table gives general restrictions; an unlisted restriction is not proof that a product is compatible.
02 What it works on
- Minerals and metal
- Tannin
- Living mould
- Urine residue (urea, uric acid)
- Polymer
- Dye
White vinegar is strongest against minerals and metal, and useful on tannin and living mould. It is part of the method in 213 stain files, for stains such as red wine, coffee, tea, cola, orange juice and beer.
03 Where it is safe
| Material | Verdict | Why |
|---|---|---|
| Marble | Never | Acid dissolves calcium carbonate, so vinegar etches dull spots into marble, limestone and travertine. |
| Granite | Avoid | Repeated acid wears down granite sealer, and some granites contain calcite that etches. |
| Tile grout | Avoid | Acid slowly dissolves cement grout and its sealer; use oxygen bleach paste instead. |

04 How the files use it
White vinegar appears in 213 stain files. The steps it is used in most:
- Soap-and-vinegar sponge (96 files): Soap loosens the stain; the mild acid keeps tannins from setting and helps lift colour. Bar soap, which is alkaline, would do the opposite.
- Soap-and-vinegar blot (73 files): This is the classic tannin spotter: the soap loosens the stain and the mild acid stops tannins from setting and helps lift their colour.
- Vinegar rinse (20 files): Wool prefers a mildly acidic clean, and bleaches strip and yellow it.
- Vinegar soak (13 files): The antiperspirant build-up is mineral, and mild acid dissolves it.
- Dissolve it with vinegar (10 files): Slime is glue cross-linked by borate; acid breaks those links and turns it back into a liquid.
05 Mixing
The combinations people ask about most, and what actually happens.
- Can you mix chlorine bleach and white vinegar? Toxic chlorine gas
- Can you mix white vinegar and baking soda? Pointless fizz, then salty water
- Can you mix white vinegar and hydrogen peroxide? Hazard peracetic (peroxy) acid
- Can you mix white vinegar and dish soap? Caution a product-dependent combination
- Can you mix white vinegar and rubbing alcohol? Caution a product-dependent combination
- Can you mix white vinegar and ammonia? Pointless an ammonium salt
- Can you mix white vinegar and oxygen bleach? Backfires a weaker soak, and some peracetic acid
- Can you mix white vinegar and enzyme cleaner? Backfires slowed-down enzymes
- Can you mix white vinegar and borax? Pointless a neutralised, weaker solution
- Can you mix white vinegar and lemon juice? Caution a product-dependent combination
- Can you mix white vinegar and enzyme laundry detergent? Backfires a weaker wash

07 Myth files
- Does aspirin remove yellow sweat stains? Crushed aspirin is a mild acid, so it helps a little. Use a labelled fabric treatment instead of assuming a homemade aspirin paste is effective.
- Does vinegar and baking soda clean stains? They neutralise each other. The fizz is carbon dioxide, and what is left is mostly salty water.
08 Questions
What stains does white vinegar remove?
It works best on minerals and metal, tannin and living mould, which is why it appears in the files for red wine, coffee, tea, cola and orange juice.
How do you use white vinegar safely?
Usually diluted: 1 tbsp (15 ml) with 1 tbsp dish soap in 2 cups (480 ml) of cool water for tannin stains; 1:1 with water for deodorant marks and odours. Never mix with chlorine bleach (chlorine gas).
What should you never mix with white vinegar?
chlorine bleach and hydrogen peroxide. Acids pull chlorine out of hypochlorite as chlorine gas, the same gas used as a weapon in the First World War. Do not combine commercial cleaners unless their exact manufacturers explicitly permit the use.
Where should you never use white vinegar?
On marble. Acid dissolves calcium carbonate, so vinegar etches dull spots into marble, limestone and travertine.
