From the maker of the popular WD-40 lubricant, these Lava wipes surprisingly struggled to shift the slime. The packet said they "clean really dirty hands", but we beg to differ. It took six towels to get the job done, which works out at nearly a pound a clean up! They seemed to only move the oil and grease around, failing to pick up and shift the dirt. There were no moisturising additives or granules to help you tackle the task, either.
