The key to removing tough stains from carpets is to act quickly, blot rather than rub, and use a method that suits the type of stain. Water-based spills such as wine and coffee respond to cool water and a mild detergent, protein stains such as blood need cold water only, and greasy marks need a solvent-style spotter. Always test any product on a hidden patch first and work from the outside of the stain inwards so it does not spread.
What are the golden rules for any carpet stain?
- Act fast. The longer a spill sits, the deeper it soaks into the fibres and backing.
- Scrape up solids first with a blunt knife or spoon.
- Blot, do not rub. Press a clean white cloth or kitchen roll into the stain and lift. Rubbing pushes the stain deeper and damages the pile.
- Work from the outside in to avoid creating a larger ring.
- Use as little liquid as possible. Overwetting can bring old dirt up from the backing and leave a brown ring as it dries.
- Patch-test every product in a hidden spot and check the carpet's care label, especially for wool.
- Never mix cleaning products. Bleach and ammonia together release toxic gas. Keep the room ventilated.
How do you remove red wine, coffee and tea?
- Blot up as much liquid as you can with a dry cloth.
- Mix a few drops of washing-up liquid into a cup of cool water.
- Dab the solution onto the stain with a clean cloth, then blot. Repeat, switching to a clean part of the cloth each time.
- Rinse by blotting with plain cool water, then press a dry towel onto the area to draw out moisture.
For coffee with milk, treat it as a protein stain too and avoid hot water. Hydrogen peroxide is sometimes suggested for old wine stains on light synthetic carpets, but it can bleach colour, so only try a small amount after a patch test, and never use it on wool.
How do you tackle grease, oil and make-up?
Greasy stains do not dissolve in water alone. Sprinkle cornflour or bicarbonate of soda over fresh grease, leave it to absorb for 15 to 20 minutes and vacuum it up. Then apply a small amount of a carpet spotter made for oily stains, following the label, to a white cloth rather than the carpet. Blot, rinse with water and blot dry. For foundation or lipstick, the same method works; lift off any excess first rather than smearing it.
What works on blood and other protein stains?
Always use cold water on blood, egg, milk, vomit and similar stains. Heat sets proteins into the fibres permanently.
- Blot with a cloth dampened in cold water.
- Apply a mild washing-up liquid and cold water solution and blot again.
- Rinse with cold water and blot dry.
An enzyme-based carpet cleaner can help with dried protein stains, but check it is suitable for your carpet fibre, as enzymes can damage wool.
How do you deal with pet accidents?
Blot urine immediately and thoroughly, pressing hard with layers of kitchen roll. Rinse lightly with cool water and blot again. Then use a pet stain and odour product containing enzymes, if suitable for your carpet, which breaks down the substances that cause lingering smells and encourage pets to return to the same spot. Avoid ammonia-based cleaners, which can smell similar to urine to a pet. If the urine has soaked through to the underlay, a surface clean may not remove the smell.
How do you get candle wax and chewing gum out?
Wax: Let it harden, then break off as much as you can. Place brown paper or a plain paper towel over the remaining wax and press gently with a warm iron on a low setting. The paper absorbs the melted wax. Move to a clean area of paper and repeat. Do not let the iron touch the carpet, and take care with synthetic fibres, which can melt. Treat any coloured mark left behind with a small amount of spotter.
Chewing gum: Hold an ice cube in a plastic bag against the gum until it goes hard and brittle, then chip it away with a blunt knife. Vacuum up the fragments and treat any residue with a spotter.
When is it time to call in a professional?
Some stains, such as old dried ones, large spills, ink, dyes, or stains that keep reappearing after they dry (called wicking), need stronger equipment to shift safely. Wool, silk-blend and delicate carpets are also best left to professionals, as the wrong product can cause permanent colour loss.
