I have had a couple of custies tell me that this was the result last time i cleaned their windows, just before I changed my filters and resin. My tds is 000 and I clean frames each visit, should I wait afew mins after cleaning the frame before cleaning the glass? eg do 3 frames before returning to do the glass on the 1st window.
Its only last time and this time I have had problems, these windows have always come up clear before.
