Product review (1 stars): Hard to clean
I own one of the dacor stainless steel gas cooktop. The stainless steel makes dark spot after every use and it is hard to clean with all cleaners recommended by Dacor. I did not know this was a real problem until I discovered this thru google! It is a money wasted in a product that should last for years as the manufacturer claims! Above all, the company completely and utterly deny this problem
