Yeap, I'm sure it would make life a whole lot easier.
If you get one, I'll send you some biz ...
Router cut PCB = lots of scrap, but no significant liquid mess = more money at the scarp yard = 🙂

if using water to clean the pcb, do you pat them dry? or have it standing up and just wait for them to dry?
better use more than plain water ...
Best is alchohol and water ... that 70% solution will do it.
Then rinse with very clean (or distilled) water ... Urban and city supplies may contain some contamination that could "tarnish" silver soldered joints and other metals, so a clean water source is called for. (The filtered, de-ionized water used in sophisticated truck washers is also good, but probably hard to find. If you have a truck stop close by that specializes in washing out the inside of tanker trucks, ask 'em if they will squirt off your boards.)
Let 'em stand out to dry, no wiping unless you feel the need, but paper towel residue and lint from cloth towels can get under chips and such and might cause high impedence shorts at some future point.
I just let 'em dry out, naturally, in the back yard or blast 'em for a short time with the little lady's hair dryer ...

when I was in the military we used Technical grade ethanol. I have been using grain alcohol ie everclear and a shaved acidbrush with a final copeious flush of electronic contact cleaner.This procedure removes even the most stubborn of very old flux.😉
