Man, that old PCB cleaner we had was driving me nuts. It broke down again last month, right in the middle of production. So I told my team - screw it, we're finding a new one that actually works.

Started searching online, but wow, it's a mess. Every seller claims their machine's the best. How's a regular guy supposed to know who's telling the truth?

Anyway, I got three models shipped to the factory for testing:

• The "Big Thunder 3000" - looked like a tank
• The "Sonic Wave Pro" - fancy touchscreen thing
• The "Stealth Clean Duster" - compact but pricey

First day with Big Thunder - what a joke. Thing sounds like a jet engine taking off. Cleaning was okay but left wet spots everywhere. And the chemical smell? My guys refused to stand near it.

Next up - Sonic Wave Pro. The touchscreen looked cool until it froze during the third test run. Had to power cycle the damn thing twice. Cleaning was decent, but couldn't handle double-sided boards without flipping them manually. Waste of time.

Finally tried Stealth Clean Duster. Quietest of the bunch - actually let people hear each other in the shop. But here's where it got interesting:

• Used 40% less cleaner fluid than others
• Nozzle didn't clog after 50 boards like Big Thunder did
• Took half the space of Sonic Wave

Ran all three machines non-stop for three days straight. Stealth Clean just kept going while the others needed breaks. Big Thunder overheated twice.

Showed the results to accounting. They nearly cried when they saw Stealth Clean's price tag. But then I pointed out we'd save $300/month on chemicals alone. Shut them up real quick.

Been running the Stealth Clean for two weeks now. No breakdowns. No complaints from the team. And get this - boards actually come out cleaner than with our old machine.

Moral of the story? Don't trust factory specs. Test machines with your actual boards and chemicals. What works for someone else might suck in your shop.
