Is this cast iron, and what is the best method to remove the built up grease?
Not installed by me and I have no idea as to how old it is. But I believe due to the weight it’s cast iron. It’s damn near impossible to get the built up grease off, I’ve soaked it in dish soap, tried the steam cleaner with a nylon brush, but I’ve been cautious about using anything too abrasive as I don’t want to ruin it. Is it safe to use oven cleaner or something similar to get the grease off? Are there more effective methods? I haven’t tried the dishwasher because I’m concerned about rust. Is this something where I’m better off getting someone in to do it? Any and all advice greatly welcome and appreciated.
