Well, it is really hard to impress me. As a performance boater for over 20 years. I have seen many products but this one completely took me by surprise. It works fantastic on lower units made of aluminum. Sportmaster lowers, IMCO lowers, No. 6 drives. I have before and after pictures that will blow you away. Literally takes minutes to clean an outdrive.

Buy this product for cleaning your drives and you will never use anything else. Awesome stuff.

<p>This product works great on the bare aluminum and painted aluminum on my trailer. It has only been cleaned once in 15 years so it was really oxidized and dirty. It didn't take hard scrubbing to get it gleaming. Great product.</p>

<p>This is the second time I have used Aluma-kleen on my pontoon boat, and each time it becomes easier to use. After finishing my pontoons, I figured I would try it on my

aluminum wheels on my expedition. Wow, I have never seen the wheels sparkle like they did, and do.

Once again, I am extremely satisfied with this product, and will continue to purchase it when necessary.</p>

I use this product every year to clean my toons before putting the boat in storage. So easy to use.

Last week I purchased , ALUMA KLEEN, FIBERGLASS CLEANER, AND THE BLACK STREAK REMOVER. I used these three products on my 1997 Grumman Pontoon boat, which at this time had dark streaking on the upper part of the boat,which I could never seem to get rid of, and pontoons what were half clean on the upper half and almost black on the bottom. Well, I started with the pontoons, followed the directions and was truly amazed. With just one application of the ALUMA KLEEN, all I had to do is spray it with a hose, and it was sparkling. I then used the FIBERGLASS CLEANER, the same way with the same results.

The BLACK STREAK CLEANER, was a little tougher to use, I had to actually spray the cloth, and manually rub it on the upper part, just kidding, after I sprayed it on the cloth, I wiped it on, buffed it off, and used a sponge with soapy water.

My boat is entirely clean and shinning, and I am greatly satisfied with these boat products, and will purchase them again.

THANK YOU BIO KLEEN, for a job well done!! Your product prices, and their ease of use is great. As for rating your products, they get five stars from me.
