On: I put a toaster in the dishwasher (2012)

The big issue is not the water that will dry if you wait but that the hot water will make something that is glued or something that has two materials that expand different when heated break.

There is no amount of letting it dry out or adding rice that will solve if things are apart.

I assume most parts of a toaster are designed to handle a bit of heat

Also, corrosion/oxidation and any chemical interactions with Dish powder (if that was used) that might not be noticeable at first

This is a detergent selection problem. There are many detergents (like enzyme based) that are specifically designed for not corroding metals.

In part, sure, but given that we're talking about a dishwasher here (as opposed to an electronic device washer), I think it's not a stretch to assume using dishwashing powder. Which won't be highly corrosive, but certainly does interact with aluminium. But even without detergent, contact with water can start things rusting pretty fast.

I'm talking about dishwasher detergents. If you use your dishwasher for copper/aluminum pans, there's a good chance you're already using them.

And detergent might wash away grease or oil from parts that need it.
