H.V.A.C. patina removal

We apply our surface treatment on air conditioning equipment and some of our applications are existing copper coils and fins. these coils and fins are difficult to access and we have not been able to find a cleaner that allows us to spray on and pressure wash off. I am hopping you have a solution for us.

Thanks,

You very probably are going to have to develop an arsenal of your own special designed lances.

First of all, I am surprised that you want and need to clean these types of parts to that cleanliness. To my knowledge, when assembled these will not be seen or noticed that much. If you are that concerned then why don't you use an ultrasonic dip type tank. Pressure systems behave like sand blasting or will produce uneven results depending upon the direction of the pressure.
