California Custom – Aluminum Deoxidizer Cleans & Deoxidizes Metal Surfaces, Removes Rust, Great for Aluminum, Brass, Copper, Chrome, Silver, Stainless & Gold, 1 Gallon

Been using this product since day one it came on the market it's never let me down

I have tried many products for cleaning aluminum transmission housing and engine blocks this is hands down the best I found to clean them. if I could buy a 55 gal drum of it I would just to dunk trans and blocks

I have a 20ft enclosed trailer with diamond plate all around the lower 1/3. This product makes polishing much easier but the first time I used it I made the mistake of spraying it on all the diamond plate first. Letting it dry is the mistake. If it sits, it will make the job worse. Work small areas and it's amazing. Apply, wait 5 min, then apply polish.

I have ordered this product 3 times now and so far, the first two orders have been "undeliverable" because the shipping company has reported the product damaged once, and lost the second time. I'm trying a third time because the product is completely worth it. I have used this product and seen it used on very old surfaces and when it's complete it looks brand new with not a lot of effort. This paired with the second step is worth the price of it. It may seem like a lot, but you only need a little of this product to get the results you want.Unfortunately, the downside is trying to order it and get it delivered without being damaged or lost. As long as it gets delivered you won't be disappointed.

Never got to use. Bottle showed up in a soaked box. I opened it an it was pretty much an empty container the cap was in pieces and there were Pieces of it in the bottle. Waiting for my replacement but found something else in the meantime so will be returning.

This stuff is awesome. It takes oxidation and rust right off and using this with polish leaves a mirror finish. I was amazed it worked as well as they claimed. But it did just that.

worked wonders on my aluminum trailer needed to be revived pulled all the road grime off and ready for polish

........very surprised!
