Lubricating oven rails
Thanks all. Good advice as usual. Looks like first step is to try and get them clean. The ball bearings are internal and no obvious way of dismantling them. Our oven is a Siemens if anyone has experience of these.
A couple of you have suggested caustic soda. Any idea of ratio of caustic to water I should use? I can soak them for a while and see what happens.
Thanks
