The difference in our old Cincinnati core machine after a deep clean

I mean, the thing was basically a dust bunny farm for like two years, idk how it even ran. Last week we finally took a full day, pulled every panel, and used a pressure washer on the inside. Now it sounds like a quiet hum instead of a dying lawnmower, and our scrap rate on gray iron dropped from 8% to maybe 2% overnight. Has anyone else had a machine that was just begging for a clean-out?

Our old Bridgeport mill ran hot for years until we finally blasted the coolant lines clean.

Pressure washing the inside sounds risky to me, water and old electronics don't mix. I'd never go past compressed air and a good vacuum on our older machines, too worried about starting a corrosion problem or shorting something out. That scrap rate drop is impressive, but I'd be watching for new electrical faults over the next few weeks.

We've done over 200 boards this way. The key is using distilled water and getting them bone dry fast. Haven't seen a corrosion issue yet.
