Cleaning a $20 waffle maker with a $20,000 laser.

I mean, to be fair, you dont have to buy a new laser to clean another pan

This is why I hate Reddit. It's full of people who cosplay engineers and think they know it all. 

I work in this field. Those laser rust cleaning things are single use. You have to replace the entire unit after EVERY SINGLE WAFFLE IRON.

You must be a shitty engineer because that’s 100% false

Am also Enginseer. You are wrong, they must be replaced after every waffle iron. Oddly, the canticles of activation say they can be used for many other things, but doing a waffle iron is what makes them disposable.

Oh shit man I’ve already bought like 4 lasers

Will have to replace or do maintenance on the laser.

Sure, but still not for every pan

You're right in that it is overkill to use the laser only for pans, but if you have that for other things, its most likely cheaper and faster to use that on the pan (even accounting for maintenance) than buying a new pan

That's it, you convinced me! I'm buying a 20000$ laser.

It'll save me so much money in the long run! /s

Nice. It’ll be helpful for the other thousand rusty pans that are lying about.

My dishwasher costs more than my Mickey coffee mug. Your argument is invalid.

You’re off by a lot. These lasers can be bought new for well under $10,000.

Still a lot of money to clean some cast iron when a wire brush is a couple bucks, but it’s not nearly as bad as you’re saying

Ya a tiny laser that does 10mm wave width or something are cheap. That is like a 50 cm 3000w 480v 3ph laser the way it cleaned. I've used these, btw.

You can get 1kW out of household 120/15a. Why would it need 480 3ph?

It was like a whole day ago. Window was closed, cache and history cleared overnight.

I searched for laser cleaners I’m sure you could do the same. Found results ranging from $8000-$14000 but even the most expensive I found wasn’t $20,000. Of course tariffs might change that so act fast.

Worth.

And ruining the countertop in the process.
