Walked into a shop in El Paso that changed my whole view on injector cleaning

I was in El Paso last month visiting my cousin and he dragged me to this little diesel shop called Rojas Diesel Repair. I figured it would be some back alley operation, you know? But the owner let me watch him clean injectors using some ultrasonic setup (not the cheap ones you see on Amazon either). He showed me the before and after on a Cummins injector and I swear the improvement on spray pattern was night and day. I always thought those ultrasonic cleaners were just a gimmick for home use, but seeing it done right in a real shop with the right solution and cycle times totally flipped my opinion. Has anyone else seen a pro setup like that change your mind on something you thought was BS?

Same thing happened to me at a shop in Phoenix, total game changer on how clean injectors can actually get.

Whoa, hold on. You're telling me a regular shop actually got injectors that clean? I've never seen that before, mine always come back looking a little better but still kinda dirty. That sounds almost too good to be true honestly. How long did it take them to do it? I've wasted so much money on shops that just blow air through them and call it done. I'd love to know what kind of machine they used if you remember. Makes me wonder if there's a place near me that can do real work like that.
