To use this brush kit, start with the soft washing brush to gently clean the frame and components. The detailing brush is handy for small, hard - to - reach spots. Use the claw brush on the chain, cassette, and sprockets to remove mud and dirt. The rim and cassette brush can be used to clean rims and spokes. And the two - prong brush is great for those really tight areas. When using the brushes, don't apply too much pressure on delicate parts to avoid scratching. After each use, rinse the brushes thoroughly with water to remove dirt and debris. Let them dry completely before storing. This will keep the brushes in good condition and ready for your next bike cleaning session.
