1. A scrubber comprising:
foamed melamine resin particles,
first foamed polyurethane resin particles, wherein the first foamed polyurethane resin particles are non-rigid,
second foamed polyurethane resin particles, wherein the second foamed polyurethane resin particles are rigid, and
a binder,
wherein an amount of the foamed melamine resin particles is 5-25% by weight of the scrubber, an amount of the first foamed polyurethane resin particles is 15-70% by weight of the scrubber, an amount of the second foamed polyurethane resin particles is 5-25% by weight of the scrubber, and an amount of the binder is 20-60% by weight of the scrubber, and
wherein the second foamed polyurethane resin particles have a stiffness which is 10% to 500% higher than the stiffness of the first foamed polyurethane resin particles and the foamed melamine resin particles.
