The method substantially removes a soil spot (resulting from a beverage spill or the like) from a carpet by using a particular type of brush. The brush has (a) a detachable handle, (b) a body with a pair of holes therein for attaching the handle to the body at either hole, and (c) first and second brush portions on first and second brush faces, respectively. The brush portions have differing stiffnesses and either portion may be used to "de-spot" carpet by inserting the handle in the appropriate attachment hole. The method includes the steps of identifying the tuft and pile characteristics of the spot-soiled area of carpet and selecting one of the brush portions for use in removing the spot on carpet having such characteristics. The handle is attached to the hole related to the selected brush portion, a granular cleaning product is deposited on the spot and such product is "worked" across and through that portion of the carpet which includes the spot.
A method for substantially removing a spot from a carpet by using a brush having (a) a detachable handle, (b) a body extending along a body axis and having a pair of holes in the body for attaching the handle to the body at either hole, (c) first and second brush portions on first and second brush faces, respectively, and wherein the portions having differing stiffness and each portion is related to a different hole, and wherein each portion has tufts of bristles arranged in rows extending generally perpendicularly to the body axis and each pair of adjacent rows has an elongate space therebetween, the method including the steps of:
