Deep Soil
Gritty soil tracked on carpet by shoes, wet or dry, will sink down in between fibers of carpet. Gritty soil has very sharp edges capable of cutting carpet yarn fibers. Vacuuming is the best means of removing the grit from deep in between the carpet fibers. Moving the vacuum over the carpet seven times - forward and back, forward and back, forward and back, forward on the next section - should remove deep seated grit.
Upright vacuum cleaners generally do the best job of removing deep-seated gritty soil from carpets. Next are combination canisters with power-driven rug nozzle. Steps can be vacuumed with the upholstery nozzle or brush attachment.

Wet cleaning of velvets, etc. should be done professionally. If protected with stain resistant finish, blot quickly and gently with lint free cloth. If stain remains, spot clean, wiping the stain in the direction of the pile. Brush lightly during drying to prevent matting. If unprotected, pretest in an inconspicuous area for discoloration or pile distortion. If color proves fast, sponge lightly with appropriate cleanin
