Scratched Silver Door

Anyone have any ideas how to get a scratch out of a Bosch Silver Slimline door.
My husbands work collegue allows a bit of copper to drop down the front of a customers one year old dishwasher and they obviously want it replaced but we thught we might as well try to polish it out first. :boops:
Going to try T cut.
Although the colour is silver I dont think its stainless steel.
Failing that anyome point me in the direction of a replacement door supplier?
Cant find out model number until tomorrow. Tried Bosh spares website but nothing comes up.
