The White Soft brush is for delicate upholstery and headliners. The Yellow Medium brush is for the toughest of stains in carpet. The Red agressive brush is great for deep cleaning of plastics and vinyl especially floor mats. Use with detergents like Pro Extract Power, Pro Heavy Duty Interior Cleaner or Tec Enzyme Cleaner.
