Ask HN: Washing Utensils with Small Rubber Balls

1 points by rohan_shah ↗ HN
Fill a tub with small water filled rubber balls to the rim.

Put water until it starts overflowing.

Now dip any utensils in it and it'll come out clean. (Unless the contents have dried.)

How's that for semiautomatic dish washing?

Well ball size and ball rougness/bristleness degree come to mind. Industry has used fluid carries cleaning agents, is sizes from sand to quite large. I imagine it would work with a dishwasher that sieved out the balls and re-used them again.

Yes, we could use multiple layers of different size of balls.

It'll be like sand blasting but softer version.

I didn't get you about the sieving! How would a dishwasher incorporate these balls?

well, a sisve in the drain would save used balls to be used again. It would also catch chicken wings or gristle. That means some care is needed. The balls can also have a magnetic core for the same reason - a magnet would save balls. Most chicken wings are not magnetic. A sieve is 100% good - catches all balls. Bad aspect is big stuff is also caught. A magnet is not 100% good as a ball trapped in a chicken wing might be an aggregate too heavy for the magnet to grab, so the ball and wing go down the drain.
