I know that plastics leach chemicals into water, but I have never heard of "water cleaned" plastics no longer leaching chemicals.
It's also worth noting that consuming microplastics doesn't result in them being bathed in water, but rather our acidic digestive tract designed specifically for leaching chemicals out of things.
Worse yet, the plastics break down in water and plankton eat them up... and they're at the bottom of the food chain, not to mention phytoplankton produce between 50-85% of oxygen [0] and eat lots of CO2.
Disclosure: Involved in a project to raise awareness about plastic and noise pollution in the water [1].
