I have to agree with Swampsinger. The bacon not only tastes good, but if the rendered fat is left to cool, one could slather it on said rusty springs, which in turn will temporarily lube them, as well as make them smell good!
In fact, I think im gonna try that with my squeaky heater motor. When i turn that on, Id rather not hear the squeal, and the smell of bacon sure beats out wet carpet!
