Dishwasher safety – “top shelf” vs. “bottom shelf”

It can be a bit tricky, a couple of tips:

• Use a lot less liquid in the blender than normal. Do batches if needed.
• Vent the lid so the steam can escape. A lot of lids have a center piece that can come out. Using less liquid will stop stuff coming out the top.
• As Ocaasi suggests, you can cover the open lid with a kitchen towel as you start to insure there's no spray.
• Start the blender slow and then speed it up. This may not work depending on how fast your slowest setting is. But once the vortex gets going, the liquid won't splash. It's only when the blades start that you have that issue. Slower start speed means less splash (a vita-mix can start very slowly and have no splash at all, great for hot liquids but the price tag is a bit high).

I've accidentally run my scoop, a Zeroll with conductive fluid inside the handle, through the dishwasher. I don't know this for a fact because I didn't cut mine open to check, but I believe what happened to mine (and what's happened to yours) is that the fluid is meant to work at normal body temperature and when it gets too hot, like in a dishwasher, it solidifies. That's the clunking sound, the now-solid conductive liquid. So while it still works as a scoop, the conductive fluid is no longer doing its job and scooping will be a little harder. I definitely noticed that after mine went through the dishwasher.
