I've also just bought a new kitchen and accidentally (that's what I told my husband) scratched the glossy worktop with a scourer which obviously took the shine off. Someone told me to clean the scratched surface with toothpaste as this has very fine grit in it and will take any grease or anything else on it and then T-cut it. He said that this is what the big retailers do when they want to sell off showroom baths and sinks (only acrylic though NOT enamel). I did my kitchen work surface and it has worked a treat - no more scourer for me though !!
