I've found some pretty old Lego Duplo train track parts, that I'm looking to sell on Ebay.
As these are pretty old and caked with dust, I wanted to used my usual method I usually use to clean all kinds of Lego parts: Put them in a duvet cover with a zipper so they don't go everywhere, and put them in the washing machine, and wash without any detergent and no spin cycle.
Afterwards I take them out of the machine (thanks to the duvet cover I can take them out just like a bag) and spread them on my terrace to leave them in the sun to dry.
As these track switchers have metal springs in them (at least I think so, judging based on the sound when moving the red thing) I was not sure, if they were just normal steel or stainless. Does anyone of you know about this, or know a way to open them without destroying them?
