Peaty's Loam Foam is a bike cleaner for professional use that puts dirt on the skin! The cleaner is biodegradable and can be used on all surfaces of the bike - including brake discs and pads.
It is not necessary to spray the bike beforehand!
Simply apply Peaty's Loam Foam generously to all surfaces of the bike, wait 3-5 minutes and spray with water.
Stubborn or dried-up dirt can be tackled with a soft brush. Then just spray with water.
