Hello.I have a problem. I am doing a short term rental at an apartment and I mistakenly used the scrubbing side of the sponge to clean this black glass / ceramic cooktop. It already had some deep scratches but there are many faint scratches now. One of the friends of the person I'm renting from said they will probably have to replace it when they move out, so I'm pretty sure they're expecting me to foot the bill to replace it.Is there any possibility of removing these tiny scratches? I've seen several articles online that state to use a baking soda / water paste to buff them out, but it hasn't really done much.Worst case, can the glass itself just be replaced or is it pretty much the whole unit? It's a Zanussi cooktop. I'll attach a photo shortly.Thank you!Images are here: http://bit.ly/2FdISnq via /r/DIY http://bit.ly/2Fkx6qB
