Stain Removal A-Z: Table by Stain Type and Surface
The most important rule in stain removal is simple: tackle the stain immediately, and use cold water on anything containing protein – blood, egg, milk, sweat. Hot water coagulates the protein and sets the stain. Blot, don't rub. And always test the product on a hidden spot before tackling the stain itself.
What rule applies to all stains?
Four steps determine whether a stain comes out or sets:
- Tackle it fresh. A stain that has just landed sits on the surface. If it dries, it binds to the fibers and becomes much more difficult.
- Cold water on protein stains. Blood, egg, milk, and sweat coagulate in heat. Always start cold.
- Blot from the outside in. Rubbing spreads the stain and pushes it deeper. A clean, damp cloth blotting from the edge towards the center keeps the stain contained.
- Test on a hidden spot first. A seam on the inside, the back of a sofa cushion, a piece of carpet under the sofa. Wait a minute and check for discoloration before treating the stain itself.
Never mix cleaning products on your own. Specifically: never mix bleach with anything other than water.
Safety: Never mix bleach with anything other than water. Bleach + vinegar produces chlorine gas. Bleach + ammonia or sal ammoniac produces chloramine. Both are toxic gases you don't want in a closed bathroom or laundry room. Keep products separate, and ventilate well.
Which product is suitable for which stain and surface?
This is the core. The horizontal axis is the surface, the vertical axis is the stain type. Choose the square where they meet. All products are first tested on a hidden spot.
| Stain | Textile (clothes) | Sofa (fabric) | Mattress | Carpet | Painted wall |
|---|---|---|---|---|---|
| Blood | Rinse in cold water, then a little soft soap. Never hot. | Blot with cold, damp cloth + drop of soft soap. | Cold water + a little salt, blot, air dry. | Cold cloth, blot from outside in. | Damp cloth, mild soapy water, blot lightly. |
| Grease | Sprinkle cornstarch/talcum powder, brush off, wash hot with dish soap. | Cornstarch, let sit 15 min, brush off, blot with dish soap-water. | Cornstarch, brush off, blot lightly. | Cornstarch overnight, vacuum, blot remainder. | Dish soap-water, blot - do not scrub matte paint. |
| Red wine | Sprinkle salt immediately, rinse cold, wash. | Blot up, salt/club soda, then mild soapy water. | Blot, cold water + a little dish soap. | Blot up immediately, cold water, mild soapy water. | Damp cloth, mild soapy water, blot. |
| Coffee/tea | Rinse cold immediately, then hot with dish soap. | Mild soapy water, blot, rinse with damp cloth. | Cold water + dish soap, blot. | Mild soapy water, blot from outside in. | Mild soapy water, blot lightly. |
| Ink | Blot with isopropyl alcohol (rubbing alcohol) on cotton pad, wash afterwards. | Rubbing alcohol on cotton pad, blot gently, re-blot with water. | Rubbing alcohol, blot - sparingly with liquid. | Rubbing alcohol on pad, blot, re-blot with water. | Rubbing alcohol on cotton pad, blot lightly - can dissolve paint. |
| Soot/wax | Scrape cold wax off, place blotting paper over, iron with warm iron. | Scrape gently, blotting paper + lukewarm iron, blot grease residue. | Scrape off, blot grease residue with dish soap. | Scrape off, blotting paper + iron, blot remainder. | Scrape gently, blot with mild soapy water. |
| Grass | Blot with a little soft soap, let sit, wash as directed. | Mild soapy water + drop of dish soap, blot. | Mild soapy water, blot - sparingly. | Mild soapy water, blot from outside in. | Mild soapy water, blot lightly. |
A couple of clarifications to the table:
- "Mild soapy water" is a few drops of dish soap or a little soft soap in lukewarm water. Do not pour liquid directly onto a sofa, mattress, or carpet – dampen the cloth, not the surface. Too much water penetrates the filling and foam and dries slowly, which can lead to mildew odor.
- Rubbing alcohol (isopropyl alcohol) dissolves ink well, but can also dissolve glue, lacquer, and paint. Stick to a small amount on a cotton pad, and blot.
- On painted walls, the type of paint determines everything. Matte and chalk-based paints tolerate little scrubbing. Glossy and washable paints tolerate more. Test on a hidden area at the bottom behind a sofa first.
When should I not use vinegar or citric acid?
Many stain tips suggest vinegar or citric acid. It works against limescale and some stains, but the acid etches natural stone. On marble, granite, and slate, it leaves dull, permanent stains that cannot be polished away at home. It can also damage untreated wood and some enameled surfaces.
The rule: never use vinegar or citric acid on natural stone or marble, and always test on a hidden spot first. If you have a limescale stain on a stone table or marble counter, stick to mild soapy water and a soft cloth, or a product made for natural stone. If you need limescale removal in the bathroom, we have a separate guide to limescale in the bathroom and shower.
What do I do when the stain doesn't come out?
If you repeat the same product over and over, you risk two things: the stain becoming permanent, and you bleaching the surrounding fabric. Stop after one or two attempts if you don't see progress.
When you should stop and call a professional:
- Valuable or delicate textiles: silk, wool, genuine leather, antique furniture, and carpets. The wrong product here is more expensive than professional cleaning.
- Large, old, dried-in stains on a mattress, sofa, or carpet, where the liquid has penetrated deep into the filling.
- Natural stone and marble with etched or dull stains – this requires grinding and polishing, not a home remedy.
- When the odor persists. If it still smells after the stain is gone, something is in the filling or subfloor.
An upholsterer, a dry cleaner, or a cleaning company with the right equipment – an extraction machine for sofas and carpets – can remove what you can't reach with a cloth. It costs money, but the market typically ranges from a few hundred NOK for a simple stain to several thousand NOK to clean an entire sofa or a large carpet (market estimate as of 2026, not a quote).
What equipment do I need at home?
You can go a long way with little. A basic kit that covers most of the table above:
| Tool/Product | Use |
|---|---|
| Clean, white cloths or cotton pads | Blot without transferring color to the fabric |
| Mild dish soap | Grease, coffee, general stain removal |
| Soft soap | Blood, grass, gentle all-purpose |
| Cornstarch or talcum powder | Absorb grease before washing |
| Salt | Sprinkle immediately on red wine and fresh blood |
| Isopropyl alcohol (rubbing alcohol) | Ink |
| Blotting paper + iron | Wax and candle wax |

If you are treating a larger area than just a stain – an entire sofa or a whole room – it might be worth reading deep clean versus regular cleaning first, so you know if you are facing a stain or an entire project.
In short
Tackle the stain fresh, use cold water on anything with protein, blot never rub, and test on a hidden spot before treating the stain itself. Never mix bleach with anything other than water, and keep acid away from natural stone. When the stain is large, old, or on a valuable textile, a professional is cheaper than a ruined sofa. If you need help with the cleaning company itself, check how to choose the right cleaning supplier – and ensure it's legal cleaning help in the Renholdsregisteret.
