Your Edfred shower and tile cleaner does the most amazing cleaning job on the boat hulls and motors that have been in fresh water and collected the inevitable marine growth and stains. I have used your product for 10 years on several fiberglass hull boats and it is the only product that gets the cleaning job done after the pressure washer and all of the HIGH PRICED MARINE SPECIALTY products have FAILED!!!
My experience has been with the freshwater lakes north of San Francisco. My current boat has been at the Marina in Lake Sonoma for 5 months during each of the last two years. Previously I trailer boated into several freshwater lakes in this area and found that even an accumulation of those one day outings gave the hull a distinct stain after a couple of months. I suspect your product may be effective for salt water too, but that is another universe that you should investigate before you advertise there. I certainly does work for the fresh water algae and stains. Edfred with a little (not much) elbow grease and some brushing on the lower end of the motor is just incredible!!!
Please keep your shower product just as it is, available inexpensively in the grocery store.
My suggestion to you is that you package the same product in a fancy bottle with boat pictures and a marine type logo, triple or quadruple the price and blow those other useless marine boat hull cleaning products right off the shelf at every fresh water marina in the US. I also recommend you test it on salt water hulls and see how it works for the shorter immersion hulls. Those damned barnacles are probably beyond anything short of napalm!
Please feel free to contact me if you want any additional details on my happy experience with your product.
