I want to see where everyone stands on this topic. I realize that some power washing companies will use water pressure only for cleaning in certain circumstances. I have always felt that using some sort of soap or chemical creates a much more efficient cleaning environment and a better result most of the time.
For instance, as an example: What is the importance of using a chemical ( or soap ) on a white vinyl fence that has green build up vs just plain water (hot or cold) as far as the level of professionalism and long term results for the customer ?
Would you say that you normally always use a chemical and are there instances where adding a chemical may be useless and counterproductive in your opinion ? ( I.E. - Like maybe in some instances of surface cleaning ).
