I have a bride who brought me edible diamonds for her cake next week. She said when she used some of them earlier they became foggy. Just wondering if anyone on here has a trick to keep them from doing that or shine them up if they become foggy? Her cake theme is blingy and these are the only diamonds besides her topper...I'd really like them to shine for her!

Thanks so much for any advice!!

try rubbing a little vegetable oil on them.

peg took the words right outta my mouth.

Yep! Veggie oil.
