Your Scratch-Free Cleaning Superhero! Ecoegg's Eggsterminator is the perfect all-round cleaning tool! Made from a unique 'flex-tech' material, the Eggsterminator changes texture dependent on it's temperature. He is firm in cold water, and soft in warm water! This means he can be used on tough grime when cold, but is soft enough to use as an exfoliator in the shower when warm. He provides powerful cleaning without the chemicals, tackling most jobs using just tap water! And even though he is strong and tough, he is guaranteed not to scratch your surfaces.
