Muc-Off Bike Cleaner Concentrate is the solution for the planet. With the 1L bottle you can get 4L of bike cleaner and thus save plastic. Reuse your old bottle and save the planet. Bicycle cleaner can also be used as a powerful degreaser in its concentrated form. If you are using the concentrated cleaner as a degreaser, simply apply it directly to the transmission area, allow it to act for approximately 30 seconds before agitating the area with a brush, and then rinse with fresh water.
