We are really excited about our new Preload 5. After testing in the field (not a laboratory with fake dirt) I personally feel it could be the best pre spray ever created. Believe me I know what a great pre spray is. After cleaning for 30+ years in the field, being on the pulse of our industry through Truckmountforums and trying everything in our industry I know what we needed. One thing overlooked by chemical manufacturers is testing on ALL 5 US soil types. By testing in the field in their area explains the mystery why a pre spray may work in one area but not another. So I have spent countless hours with my chemist formulating & re-formulating to finally get to what I consider the "holy grail" of pre sprays. So much so I will back it up with a money back guarantee (minus shipping and handling fee). Here is what makes me think it will be the best carpet cleaning pre spray ever created; Tested on ALL 5 US soil types Tested on ALL synthetic fibers in the field Mixes easily & completely Contains built in booster Cleans & brightens carpet overnight Cuts oil even on dreaded poly's Light natural fragrance Rinses easily & completely Virtually eliminates possibility browning Removes many organic colored stains Cuts easily through rat nasties Kills urine salts & odors Virtually residue-free No fillers or additives Reduces the need for spotting & spotters Extremely economical powder Powder low-cost shipping Patented hot or cold H2o2 activator View SDS information here
