Car wash brush cover made of microfibre: you can receive 1 microfibre brush cover with an inner size of 18 x 31 cm. Material properties: the car brush cover has a high water permeability and high foam permeability, and the microfibre brush cover is soft, which makes your car gentle and the dirt can be cleaned more thoroughly. High applicability: the integrated wire on the wash box makes the microfibre car washing accessories adaptable to different brushes. The cord holds the sponge firmly to the brush, so you don't have to worry about the car cleaning cover coming off the brush during washing the car wash. Mud net: inside the wash boxes or car wash brush there is a sewn-in net to prevent particles/dirt from entering the car paint through the outer plush. The rope retracts tightly into the brush housing without the plastic head coming into contact with the paint. No scratches and no cleaning marks: the car wash brush cover has a high water permeability and foam permeability, can absorb water and foam to the highest extent and has a strong cleaning power; the brush cover is soft and free from hard objects and does not cause any damage to the car paint during the car wash process.
