Daz, at last!
Here are a couple of tips I used when changing over.
I told all my custies that I was thinking of the change but had to balance the expense of it against my safety and the health and safety side
I then told them that I was going to change and would not put their price up if they agreed to stay with me for the first three cleans. I advised that it may take two or three cleans to get them flawless. I also told them after the third clean they could change back to trad if they were unhappy with any aspect of water fed.
Lastly I went the biggest gob on the round (we have all got one!) and told her what was going to happen, told her of the first three cleans ect and was met with the expected negative response. She did agree and I cleaned them 3 times over 2 days. Morning 1st clean, end of that day and then at the end of the second day. When I called on the third day to check them she gave me 3 names and addresses of her friends local to her as she was that impressed.
I had at the time 180 customers and since wfp I have now 325 and work the exact same hours as before.
I did hate it the first month as I spent too much time worrying about what people were thinking about the new system, the truth was as long as their windows were clean, they were happy.
I lost two custies and could not get two to come up good, these I passed to a trad cleaner.
Sincerely good luck.
