Sold in 1 Quart Containers - you will get (2) 1 Quart Containers Sharkhide Aluminum cleaner is an amazing aluminum cleaner you have to try, you won't believe the result! Sharkhide Aluminum Cleaner is not like the other "off the shelf" type aluminum cleaners you will find at retail outlets. Sharkhide Aluminum Cleaner is a highly concentrated blend of Acids, and cleaning agents that you dilute (with water) to suit the severity of your application. It can be applied anywhere from straight to diluted as much as 10:1 or more depending on the desired results. Sharkhide Aluminum Cleaner is best applied to dry aluminum with an adjustable tip sprayer. Set the adjustable nozzle to the finest mist possible. Mist a 6' to 8' section from the bottom up, let the foam work for a few minutes and rinse off. THAT'S IT! No scrubbing required. Sharkhide Aluminum Cleaner will not harm carpeted bunks, paint or decals. When you're done, that old dark streaked and stained finish will be gone and you're left with a clean, uniform, streak free off white finish. For the best results, a better looking finish, and a longer lasting finish we recommend using Sharkhide's Aluminum Pontoon and Boat Cleaning Kit which includes, Aluminum Cleaner, Aluminum Polish and Aluminum Protectant.
