Muc-Off presents its rehydrating disc cleaner:

The brake cleaner has been specifically developed for the quick and effective cleaning of all disc brakes.
This brake cleaner enhances braking performance by quickly removing brake dust, oil, and grease from all braking components.
The unique Muc-Off formula contains additives that rehydrate brake pads and discs to radically reduce brake squeal, protect, and extend the life of the braking system.

The brake cleaner evaporates quickly without leaving any residue.
It is compatible with rubber, plastic, anodised surfaces, carbon fibre, and painted surfaces.
