188 WHITE Professional Aluminum Pontoon & Boat Cleaner (1 quart), 32. Fluid_Ounces

This sh** is amazing!!! I put it in a pump sprayer and followed directions. Spray it on 4’ section and spray right off with lots of water. Do not let this stuff sit for long. You don’t need to. It cleans up the toons in seconds. I have never used something to clean the toons as good and fast as this stuff. The best part... no scribing is needed.

It did not take the calcium buildup off, but it works great on rust stains and some corrosion. But you can’t do what it says spray on and rinse off. Must leave on for awhile

I have a 2 year old Tritoon and noticed the toons getting a bit ugly. A friend let me use a small amount of this on them as a test to see if I liked it, and I was amazed how well it worked. I tried 2 other brands with power tools and this stuff did a better job just with my hands. 1 quart will do 1, 24' toon so purchase what you need

Zing Aluminum (Blue Label) is an extremely powerful cleaner. It will take off the stains from the lake by only mopping it on and rinsing with water. However , I was extremely disappointed to see it begin to completely remove the silver finish on my aluminum pontoons and turn them white. Also because the white was not uniform, it looked like bird do-do was on the pontoons. So now I am faced with either turning my entire pontoons white by a full application or stopping and having these white spots and sections. Also I tested a spot first and thought all was going to be okay and then later put too much on or got the same spot twice and then the white appeared as the silver aluminum finish began to be removed. Discussed with my boat dealer and they immediately knew what happened and said for this reason they use even on pontoons the red label Zing for fiberglass boat cleaning. Even if you look on the Zing website for the aluminum product you will see a bunch of pontoon boats with white pontoons. I am really disappointed in the harm I did to my relatively expensive Crest pontoon boat.

Works amazing

My husband said it works very well but doesn't go very far. We have an 18' pontoon. He was able to do the outside of one pontoon. Going to order more to finish the boat.

Works good but watch some youtube videos before you use it so you can apply it correctly.

Best stuff on Earth I've found for cleaning aluminum pontoons!!!
