PEATY'S LOAM FOAM IS A PROFESSIONAL GRADE BIKE CLEANER THAT WILL SHIFT DIRT FAST.
The solution is biodegradable and safe on all bike surfaces including discs and pads. No need to rinse the bike before use!
Simply apply Peaty's loam foam liberally to the entire bike, wait for 3 - 5 minutes (time for a coffee/beer) and blast off with clean water.
Stubborn and impregnated dirt may need to be persuaded to vacate your valiant steed with a soft bristled brush, then rinsed off with cold water.
