There's no stain the Sorbo Wonder Sponge can't handle! This unique melamine sponge erases stains and streaks from smooth surfaces, without having to use cleaning products! Stains on your white trainers, pencil marks on the table or grease caked on your cooker: all will disappear before your eyes. The soft material of this miracle sponge doesn't leave scratches, so you can use it with full peace of mind on delicate surfaces. We do however advise you always test in an inconspicuous area first, to avoid damage or dull spots. The sponge may crumble a little during use. This is normal with melamine sponges.
