Mine are also regular uncoated ADC plastic, and I wash them with warm water + dish detergent + microfiber cloth. I then rinse under a thin stream of running water, slow enough that it has laminar flow, and I angle the glasses so the water hits the lens close to parallel to the surface. The water sheets off the lens without splashing and leaves it visually flawless. I always rinse the microfiber cloth before use to remove any grit or abrasive dust, and I avoid touching the lenses with anything but the wet microfiber cloth.

I clean the same way, but dry with a lint free cotton cloth. My lenses have AR coating though
