I've read a few articles over the years on rust, rust removal, avoiding rust, machine storage etc. I realise it is a nuisance to a lot of us, but thought today I'd post what I use to avoid it - sheets.
Simply put, I throw old bed sheets over them when I'm done. Over the BS, jointer and thicknesser, no rust, or signs of it. I ensure the sheet does not sit directly on the metal but is held off somehow, for example, on the jointer I use the push handles to hold the cloth in the air.
Since I am on the handy hint thing - old toothbrushes. One of the handiest things in the shop and you can use them for a surprising amount of tasks: gluing, painting, cleaning, scrubbing blades, planes, sockets etc. But one of their best, but little known uses, is for cleaning sanding belts or disks. Don't but the so-called cleaning sticks, use an old toothbrush.
