original light grey color grates stained and unsightly--no amount of scrubbing or cleansers would make them look nice.
Opened the box and took out the black color grates~~removed discolored grates and put the new ones on. Looks like a brand new stove and much nicer to look at as it is the first thing you see when you enter the kitchen.
My knob cracked and was hard to turn stove top on. I went online and searched your site for a replacement knob. The kit replaced all 4 knobs for a reasonable price. I replaced them myself without any tools. Now my stovetop has a new look and I don't have to fight with the knobs.
I pulled off my knobs and put on the new ones from the kit I ordered from you. They were a "D" fitting. I did do a little cleaning before putting the new ones on, but it was really easy.
