High-Quality Materials The auto sunroof drain cleaning tool is constructed with POM plastic, steel wire, and nylon. POM plastic is a synthetic resin with exceptional hardness, rigidity, and wear resistance. The high-quality steel wire is pressure-resistant, wear-resistant, non-brittle, and does not easily age. The soft nylon bristles are resistant to breakage, ensuring a gentle yet effective cleaning process. This makes the cleaning water brush reusable for the long term. Flexible and Long Enough This car drain hole cleaner is long enough to easily pass through long, narrow pipes. It helps clean car sunroofs, fuel tank drain holes, door drain holes, and other areas more quickly and safely, effectively removing dirt and debris. Nylon Rotating Bristles One end of this sunroof drain cleaning brush features a tubular-shaped brush made of nylon rotating bristles that are soft and non-scratch. It gently removes leaves, dirt, cobwebs, and debris, and can be reused over the long term. It helps clean stains effectively while protecting your vehicle from scratches. Practical Hand Ring Design The other end of this hose pipe brush includes a hand ring for easy extraction. The handle is smooth, rust-resistant, and durable. The design prevents the brush from falling into the hose and makes it easier to hold. The hand ring color may vary. Wide Application This flexible drain hole brush is suitable for car sunroofs, auto wipers, fuel tank drain holes, car door drain holes, skylight drain pipes, and more. It is also ideal for refrigerator drain cleaning, fish tank cleaning, hose or glass tube cleaning, water pump accessory cleaning, and filter system cleaning.
