I think they get points or payment per post, but I don't know if it counts if they go away right away, so we make them disappear completely.
Loading the dishwasher with a few items this morning and am including the big plastic fan from the range hood. It ends up off-balance due to buildup, so though I soaked in the sink and scrubbed already, I'll give it another cleaning this way. The housing itself needs a lot of attention also, a full afternoon enterprise. There are parts I can't reach unless I take the entire thing down, I don't know that I'm that gung ho about the job. (I always use the dishwasher on air dry to prevent plastic things from warping—double-checked to be sure that was the setting before starting this!)
