In general, synthetic rugs are often able to handle the moisture and pressure of a carpet cleaner, but rugs made of natural materials like wool or jute may be ruined by the excessive moisture and detergent.

Mix 1 teaspoon (4.9 ml) of wool detergent, 1 teaspoon (4.9 ml) of white vinegar, and 4.25 cups (1L) of warm water. Dampen a cloth in the solution, lightly rub and dab the stain. Now use a damp sponge to remove the cleaner. Blot all water up with a dry paper towel and let the area dry for several hours.

Rubbing alcohol is a great way to clean your carpets without leaving behind any residue. As it evaporates quickly, it won't soak into the fibres of your carpet, which can potentially cause more trouble than the original stain!
