Quality Chemical Aluminum Brightener & Restorer - Aluminum Wheel and Pontoon Cleaner - Rim Cleaner 128 oz (pack of 2)

This stuff works amazingly well. So much so that I bought some more. Make sure you wear proper protection. It burns if it gets on your skin (first hand experience… no pun intended).

Works great

REALLY BRINGS OUT THE SHINE. I ORDER THIS OFTEN AND AM ALWAYS HAPPY WITH THE COSTS, SHIPPING, AND QUALITY OF PRODUCT

Clean aluminum like you would not believe really good.Easy to use

I'm not sure what is in this stuff.. The SDS says that there is nothing harmful as defined by OSHA. I don't know if that is just because the concentration is low enough or what, but it does say it will etch glass, which a lot of acids won't. This lead us to think that it may be hydrofluoric acid, which is some real nasty stuff. The valve covers and intake parts are off of a Subaru engine. I soaked those parts for 15-20min in a 1:4 ratio of Alumanew to water and then pressure washed the black residue off. I also tried to soak the engine block, which is all aluminum except for the iron cylinder walls. I got mixed results on the block. It still required scrubbing. I wouldn't recommend using it on a disassembled engine block or cylinder heads, because this stuff will get into every hole and passage and require using brushes and WD40 to get it out and stop the reaction. Definitely wear protective gear, eye protection, long sleeve gloves and use it outside if you're using it in a stronger ratio than recommended. You'll definitely want to use eye protection while washing the parts off. While soaking your parts you'll notice bubbling/foaming and an increase in temperature of your solution. I noticed some eye and nose irritation when I got too close to it. Stay upwind of it when pulling the parts out or soaking it. Just do it outside away from where you're working or waiting. Whatever you soak will come out with a black residue all over it. Using a pressure washer will take it right off, otherwise you will need to use a brush and/or fingers and fresh water to clean it off. This stuff will also strip the protective plating off of steel parts/nuts, bolts. Would I use it again or recommend it? Depends on how intricate the parts are and how many deep holes/passages there are. I soaked the water inlet housing, which is all aluminum with no steel attached to it and I was surprised at how well it cleaned all of the build up off of it. It's worth giving it a try if you're ok with the dull aluminum finish. Just be careful using it and wear appropriate PPE like I said before.

I use a garden sprayer and cut this 3 parts water to 1 part acid. Spray or on from bottom to top in manageable sections and watch it work for 3-5 minutes. Cutting from full strength keeps from having a lot of streaks, and gives me enough to go over my pontoons 2 times per gallon. Note: it is acid, and fairly strong. It will burn your skin, and will slightly etch concrete, so be liberal with rinsing everything it touches. Will NOT shine your aluminum, but it will clean it without scrubbing and return it to light gray. If you want to polish, that's a whole different process.

I put this on my toons - followed directions - and I have streaks. Don't know how to get them off and they look terrible. It did clean them up and make them look really clean otherwise.

This product cleaned my aluminum trailer very well. I recommend that you use it.

great stuff

nettoyer les ponton de mon bateau

very good does what it said

Works better than advertised. Highly recommend

I have used other products like this before on aluminum stock trailers. This product made a mess of the gooseneck portion. Will have to take to a professional to fix. DO NOT BUY THIS CLEANER.
