I really wish I could justify the cost of a 2000w laser cleaning machine.
I've priced them out for projects before. The ones I was looking at were around $250k. I'm sure you can find them much cheaper now. They would be amazing for rust removal. If you had a welding shop where you had to clean up a lot of steel I bet something like that would pay for itself quick enough that it might make sense to buy it.Quote:

Oh that's just the cost of a good welder. That's not bad at all.Quote:

Would CO2/dry ice blasting work for rust removal? It's great for removing other material from metal I have no idea what the machines cost, but they don't leave media behind - only the removed material.Quote:

It is my conviction that rust is a living organism feeding off of the base metal while combining it with oxygen moisture and the micro minerals in the air otherwise how can it grow to half an inch thick between the layers of paint and the base metalQuote:

There is a product I often use to dissolve rust and mill scale on new materials, but it is slow, even though it contains the highest percentage of phosphoric acid concentration that can be purchased without a license.
I'm thinking maybe that is being used by Servpro or something similar. They clean up after fires and other messes.Quote:
