This little brush definitely has a cult following! The durable felt like material is very effective for scrubbing and cleaning leather, vinyl and hard plastic surfaces. Use in a jitterbug motion with your favorite leather and vinyl cleaner to get dirt, grime and mildew from the hard-to-clean grain on leather and vinyl. It works wonders for removing mildew and other buildup on marine seats and vinyl too. Its soft polyurethane handle makes for a comfortable and solid grip.
