Vacuuming once a week will do (more often in heavy traffic areas.) This is an effective way to remove dirt before it becomes embedded in the pile of the carpet. For best results, empty the vacuum bag when half full.
Spot & stain removal
Blot up liquids with paper towel or absorbent cloth. Scoop up solids with the end of a knife or spoon.
Treat spots with a spot removal agent which is suitable for wool (when a wool carpet) and is pH neutral, and which is explicitly recommended for cleaning carpets and rugs and leaves no sticky residue.
Always follow the manufacturer's directions when using commercial products.
Use a light, colourfast cotton cloth for the treatment of spots.
Always work from the outer edge towards the centre to prevent spreading. Use only small quantities of spot removal agent. It is a good idea to replace the cotton cloth as soon as it is soiled.
Carefully rinse the area with clean water and a sponge after having cleaned it. Do not soak the carpet pile. Subsequently blot as dry as possible with a clean towel or with a hairdryer.
Do not use household cleaners such as soft soap, neutral soap, ammonia solution, turpentine, petrol or spot removal agents which are only recommended for textiles when you have a woollen carpet.
Place absorbent mats at entrances to your home. Change or wash when these mats become dirty.
Regularly change filters in your heating and air conditioning system.
Clean traffic lanes and areas in front of chairs periodically with a suitable cleaning agent.
Do not apply stain repellent treatments that contain any silicone, because they tend to accelerate carpet soiling.
