Hi All

I have an oven which has telescopic rails which allows certain shelves to slide out on arms. They are now getting a bit sticky and one of them struggles to go all the way in. Was wondering what the best oil is to lubricate it.

Conscious that the oven goes up to about 300c so wondering if WD40 / 3 in 1 oil is ok at these temps or whether it will burn off. I also thought about vegetable oil.

Any thoughts appreciated

Thanks

Lee.

WD40 is almost the same as white spirit. It's not a lubricant.
Vegetable oils turn to very sticky gum, especially in high temps, the last thing you need.
Oil is the problem, not the solution. Clean the thing out, don't relube it. Ammonia or caustic soda are the things to get baked grease out.
