I clean off every scrap of dirt I can find, then I polish everything to a high finish before wrapping it all up nice and tidy and wishing it sweet dreams. !
Needless to say, I seldom switch it on No-N0-No, that,s not good for it, it,s only there to be looked at, not used !
However, in the real World, I use it to get the job done, then clean off the heavy muck before getting on with something else. I regard it as a machine to be used, not to be looked at. I can buy ornaments cheaper.
