I just got a new job about a month ago as culinary manager/chef, and there was a lot of cleaning projects to be done. I've had everyone do a lot of deep cleaning, but I'm wondering what the best way to tackle the stove is. I was thinking of just turning them upside down, burning them for a couple of hours (while keeping an eye on it) and throwing it into a sink filled with water and degreaser. I did that with one stovetop for an experiment for about 2 or 3 hours, and it only came away half clean. Does anyone else have a good method for cleaning stove that just have years of built up, burnt grease?
