This 9-in-1 comprehensive cleaning kit includes: one large, heavy-duty stainless steel brush for large-area cleaning three small stainless steel brushes for vigorous scrubbing three nylon brushes for delicate surfaces and two precision metal scrapers. The high-density stainless steel bristles effectively remove stubborn rust, welding slag, and thick paint layers while resisting shedding. The flexible nylon brushes clean plastic, upholstery, or delicate automotive trim without leaving scratches. Ergonomically curved handles feature an offset, non-slip design to protect knuckles from impact. The large orange brush includes finger-fitting grooves, making it easy to apply high torque while scrubbing. Two durable metal scrapers handle stuck-on grime, old gaskets, or peeling paint. Small angled brushes reach deep into tight corners and crevices. Suitable for use on barbecue grills, spark plugs, window tracks, engine blocks, and more. Weight: 0.99 lbs.
