For most spills, quick action and clean water are all that is needed to remove a stain or prevent it from setting in. Cleaning up the spilled matter immediately decreases the chances that it will cause permanent damage to the carpet.
Blotting gently — beginning at the outer edge of the discolouration and working inward — is considered the safest way to clean the spot without causing additional damage. Scrubbing or rubbing the stained area is not recommended, because it may weaken the carpet fibres and cause the stain to spread or become more deeply embedded in the fibres.
The first thing you need to know is to act fast, while it is still a spill or a spot rather than a stain. Many carpets today come treated with stain-resistant substances, so spills can be removed easily if you get them right away. The longer you delay, the more difficult removing those stains becomes–and there are no stain-proof carpets
When it is a liquid spill, blot it up carefully; don’t rub or you may make it worse. As much as possible try to always use clean white cotton cloth or plain white paper towels (ones that do not have any coloured designs printed on them). Just put the cloth on the spot and let it soak up the liquid, pushing down gently and starting with fresh rags or paper towels as necessary.
When you have removed as much of the liquid as you can in this way, rinse the spot with water and blot again until dry. Don’t pour too much water on the area though. Dribble it on carefully or use a spray bottle. Repeat if necessary to remove more of the stain, but don’t scrub the area, or you may damage the carpet and set the stain in more permanently.
Peanut butter, pudding and other semi-solid substances can be scraped and lifted gently with a spoon or dull butter knife. Rinse the remaining spill out and blot dry. Repeat the rinsing until you get no more transfer of the substance to the cloth and can no longer smell it in the fibres.
If semi-solids have already dried they should be broken up and vacuumed first. Use your fingers to break them up or carefully pinch them between two spoons. Continue breaking it up and vacuuming until it is essentially gone. Then rinse the spot with water and blot dry.Repeat the rinsing if needed.
Use Water for Most Stains
Whenever you are not sure how to get out carpet stains, try water first.
When using a cleaning solvent, apply it to a cloth first, then work it in from the outside of the stain to the centre, so you don’t spread the spot. The procedure is to apply the cleaner, extract (blot), rinse, extract, and repeat until you can’t get out more of the stain. Always extract solvents completely.
