I have a brand new Thermador gas range which I've been using for less than 2 months. We cook a lot with butter and oil and I'm desperately trying to figure out how to get off the tiniest of grease splatters without using anything abrasive. Every night after cooking I use hot soap and water and a microfiber cloth to shine but there are pesky splatters I just cannot get up. I have tried Dawn, 409, Windex, liquid Bar Keepers, etc. I know this is a range and meant to be used but there has got to be an effective cleaning method. Please help!
