Tiva Clean Electrocleaner (1lb)

I was surprised how little powder it takes to make a full gallon of solution—that 1lb tub will last a while. The bright green color when mixed is oddly satisfying to watch, and it cleaned my plastic parts without any etching.

I was a little skeptical of the fluorescent green color, but the powder dissolved instantly in warm water and the plastic part I cleaned came out looking brand new. It only took about ten minutes of soaking to remove what looked like old grease.

This stuff mixed up into that bright green liquid exactly as described, and it cut through the grime on my old plastic parts without any scrubbing. A one-pound tub goes a long way since you only use eight ounces per gallon.
