Cleaning your bike after a rainy ride is often the biggest headache for cyclists, especially when water residue and rust tend to accumulate in crevices and around screws. This episode features an ASMR-style presentation with only the sounds of washing, no narration, as we dive into the deep cleaning process of both the bike and the chain. The camera zooms in on the aggressive degreasing of the chain using organic solvent, and for the first time, we bring out a powerful "pet blower" originally used for pet grooming to test high-pressure air drying on derailleurs, calipers, and hard-to-reach screw areas. Can this budget blower's airflow rival a professional air compressor? What surprises does the chain's running sound hold after cleaning?
