Review on 🚲 Muc Off Bio Drivetrain Cleaner: A 500ml Biodegradable Bicycle Chain Cleaner Spray for All Bike Types by Kevin Johnson

Great product but the pump literally doesn't work the first time. The pump supplied with the product is unusable. I had to buy a spray bottle and bottle to use this. Update: Changed from 4 to 3 stars due to the pump. the product itself is excellent. The pump literally fell into four parts. the pump does not turn on. After using homemade pump parts to cap the bottle, one of the parts fell off leaving the bottle open to the air. 1/2 of the product evaporated before I knew it. I bought a 3.00 spray bottle for on site use that works great.
