The Complete Carpet Stain Removal Guide

No — it is one of the most persistent myths in cleaning. White wine is also acidic and also contains tannin and sugar, so at best you dilute one stain with another and leave sugar in the pile that attracts soil for months. Cool water and blotting does everything white wine would do, without adding a second spill. If you want a household mix that genuinely helps, use a tablespoon of white vinegar and a teaspoon of washing-up liquid in 500ml of cool water.

Salt draws some liquid up while it is still wet, which is why it looks like it is working, but it also drives pigment down into the backing as it dissolves and it leaves a gritty residue that abrades the pile. Professionals do not use it. A thick pad of white kitchen roll with a heavy book standing on it pulls liquid out of the backing far more effectively and adds nothing to the carpet.

Often, yes — it depends entirely on the family. Old tannin stains such as tea and coffee respond well to acid-side chemistry and controlled heat even years later. Old protein stains usually clean up with enzyme treatment unless heat has already set them. Old dye stains such as curry and hair dye reduce rather than disappear. And if the mark is bleach or colour loss, age is irrelevant — the dye is gone and only re-dyeing or patching will change it.

That is wicking. The spill reached the backing or the underlay, the surface was cleaned, and as the deeper moisture evaporated it carried the remaining stain back up to the tips of the pile. It is the classic sign of a spot clean that treated the top third of the carpet only. The fix is a proper rinse and extraction that reaches as deep as the original spill, followed by weighted drying — not another surface spray.

Oxi-type products are formulated for robust synthetic carpet, not for wool. On wool, oxygen bleach and high-alkaline chemistry can strip lanolin, dull the pile and lift dye, and the damage is not reversible by cleaning. If your carpet is wool or a wool mix, use cool water, blotting and a WoolSafe-approved product only — and always test on a hidden patch first. If you are not sure which fibre you have, that uncertainty is itself a reason to stop.

By treating volume, not surface. We locate the full extent with a UV lamp and a moisture meter, then flood the area with an enzyme treatment in roughly the volume the animal produced so it reaches as deep as the urine did, give it a proper dwell time, and extract sub-surface. Odour comes from uric acid salts, which is why perfumed sprays fail and why the smell returns on humid days. Where urine has reached the underlay or the floorboards, no surface clean fixes it and we say so.

Not by cleaning. A bleach mark is dye loss: the colour has been chemically destroyed, so there is nothing left on the fibre to remove. The two real options are spot re-dyeing by a colour-repair specialist, who mixes to match the surrounding carpet, or a patch repair cutting a piece from inside a wardrobe or from an offcut. Both are trades we refer out, and either is a better use of money than any product promising to restore colour.

Keep three things rather than one miracle spray: a bottle of plain white vinegar for tannin stains, an enzyme cleaner for protein and pet accidents, and a small bottle of surgical spirit for ink, make-up and grease. Add a roll of plain white kitchen roll and a couple of white cloths. That kit covers the overwhelming majority of household spills, costs less than one branded bottle, and never makes a stain worse through the wrong chemistry.

Only once you know the stain family, and never on an untreated protein stain. Domestic machines heat the water, which is exactly wrong for milk, blood, egg, vomit and urine, and they put down far more water than they recover — which is how wicking starts. For a fresh spill, blotting and a correctly matched spotter beats a machine every time. Save the machine for general soiling, and empty and rinse it properly or it will re-deposit old soil.

Within the first minute for liquids, and within the hour for anything oily or dye-based. Fresh spills sit on the fibre surface, where blotting removes most of the material before any chemistry is needed. As it dries, the stain migrates into the pile and towards the backing, oxidises, and in the case of dyes begins bonding with the fibre. The difference between minute one and hour twelve is usually the difference between a complete removal and a permanent shadow.
