  • Patent number: 4130443
    Abstract: Disclosed is a method and apparatus for cleansing roller-type applicators comprising a container, means for supporting and rotating applicators placed inside the container and means for spraying solvent on the rollers. One of the supporting means has a trough which enables the applicator to be cleaned whether or not it is mounted on a handle assembly. To obtain the desired cleaning action, applicators placed inside the container are sprayed with solvent while being held stationary or while being rotated slowly. Thereafter, the applicators are rotated at a high rate of speed to force the solvent with dissolved contaminants out of the applicators.
