Ok so i have used 4 6.5 lb jars of this stuff. It cleans and rinses well especially with the secret formula prespray. But this stuff builds up in all solution screens. I have even went to just mixing 4 oz per 5 gallon jug. I am done with this product. Too much build up. Sorry Rob but this one needs to go back to the drawing board. Your prespray tho kills good job.
