This premium brush is perfect for agitating interior cleaners while simultaneously pulling dirt and stains from soft surfaces. The brush has medium-soft bristles that clean without abrading sensitive fabrics, carpet fibers or leather grains. In this way, the Upholstery Brush has been specially developed to maximize the effectiveness of your interior cleaners by ensuring maximum contact with each area and by removing any spent cleaning agent (solution that encapsulates the maximum amount of dirt) and ensuring that it is replaced with fresh solution. Instead of physically scrubbing, this high-performance brush gently massages fabrics to remove deep-seated dirt, allowing your cleaning solutions to break down and encapsulate potentially harmful particles so they can be safely wiped away.
