Steve,
In my opinion, with the introduction of non detergents etc. a lot of CCs in particular those starting up in recent years, also some who have been at a lot longer have gone OTT, expressing opinions about detergents as the evil to avoid. This is of course a load of Bull. I used porties for 23 years with detergent in the tank, cleaned thousands of different suites without nuetralising and with not a single problem, and I never once turned down a clean. If you use the proper equipment, detergents, techniques and care and know what you are doing you should be okay. Problems with detergents AND other solutions occur through misuse, typically - too hot, overwetting, uneveness, wrong pH etc.
Why not try a detergent that self neutralises, you then dont have to bother with a separate misting. Alltecs, Ulltimate Master is the one I prefer for outstanding results and maximum retention of cleaning.
Dave.
