Let the dust fall naturally:Instead of vacuuming, turn the carpet upside down and step on it to let gravity naturally pull the dust to the ground. Leave it like this for 2-3 days and use wedges to lift the carpet and separate the wool from the ground.
Marseille soap and wool product:For stains like coffee, sauce, or chocolate, sponge the stain and then use Marseille soap or a special wool carpet cleaning product. Use gentle and regular movements to avoid damaging the carpet. Dry the carpet in the sun after cleaning.
