splash Ah, I didn't think of that. You'd have to have one of those all-over suits and a HAZMAT team of cleaners on-hand for afterwards.
I suppose you could fill a reservoir and work below the water line to minimize splash.
I like where you are going with that, but the time needed to clean chips in quantity means a lot of time with hands submerged. Gloves would help (I would likely use them with the toothbrush standard anyway), but you would need to frequently dump the reservoir as the waterpic filled it up. I'm just afraid that the process is just more time consuming and more effort than just using a toothbrush.
Now if you could build an conveyor belt, recycle the reservoir water (with filters) back into the water-pic, and have the pick sweep back and forth automatically. You would have something... like a really, really small car wash.
Does anyone have one of those Matchbox/Hot Wheels car washes?
