O Gauge Jim posted:If you use compressed air to clean your trains you’re not getting rid of the dust, you’re just blowing it into a different place. I installed a built-in vacuum system when I built my house with two inlets in the area I was going to use as a train room. On reasonable intervals I use the vacuum system with a soft brush attachment to vacuum the trains. Then about once a year I use the old elbow grease method and carefully clean all of my trains. I have about 150 feet of shelves with trains coupler to coupler so it might take a day or a day and a half.
You can certainly use a portable vacuum to accomplish the same thing. It might even be easier.

I like your method, especially using an open window so as to not just redistribute the dust.
I have found that Electrolux has the softest bristles on its round dusting attachment.
