The Sponge is a clever design with "monutains" and "valleys" which trap any dirt and help prevent wash marring and scratches.
It is made of premium synthetic foam which is soft enough not to scratch but not so soft that it doesn't clean!
Sponges get a bad reputation, but we think The Sponge is a valuable tool in any arsenal.
They last longer than mitts, they are easier to keep clean, they release dirt back in to the bucket easier and are better ergonomically.
Best paired with a grit guard during a wash.
Pre Wash is also essential to remove as much hard solids as possible before a wash.
Try one and you won't be disappointed.
