We, like others, cleaned the oven with the telescopic racks, which we love. Based on the reviews, we purchased this high temperature lubricant. My husband took the racks apart, soaked and cleaned them in hot soapy solution, dried and applied a small amount of the lubricant to the ball bearings. The lubricant appears to be a graphite based product. The first time we cooked in the oven, all the racks were frozen and there were silvery flakes in the oven from the lube. We were able to salvage 3 of the racks by taking apart and cleaning again. We had to replace 2 at $275 each. We will probably have to replace the others eventually.
I would not recommend this product at all.
