Fight the tide if you wish but O/P machine use is growing in the US and Canada because .......with the right product and the best pads they do an excellent job. So good apparently, that T/M operators are going over to O/P cleaning.
Anyone whose paid out thousands of pounds for a T/M is unlikely to want to hear they could have a very effective cleaning system for a tenth of their ouitlay which costs pennies per job, can be carried around in a small van, has high productivity and gives clients what they want.
I was amazed at the results I achieved with my Texahterm system and they would have been even better with an o/p machine.
I wish I had one. It would extend my c/c for a few more years.
