Aluminum Brightener/ Stain Remover / Cleaner & Restorer / Made in USA / Quality Chemical / 1 Gallon (128 FL Oz)

Amazon product description and instructions - state "EASY TO USE - Simply mix 1 part cleaner to 4 parts water, apply to surface..."Going to the MANUFACTURER - they state 1:15. Which for a 32 oz spray bottle is 2oz's with 30oz's of water. Which is what I mixed it at. 1:15Sprayed on; left a minute - briefly used a brass brush; rinsed with clean water. Cleaned the metal quite well. No complaints. This was a small engine water port part (fixing a Kia; installing a Cylinder head). After the C head is installed - I am going to spray onto the Block - leave it for a couple of minutes - then Pressure wash rinse with clean water. Not going to use a wire brush. From my limited experience with this product - I expect that procedure will work fine.I STRONGLY recommend not to mix at 1:4!! From my and manufacturers recommended 1:15; 1:4 is going to cause problems. The descript also states it is fine for ALL Aluminum. Nope. Not Polished; and not Anodized. So if your aluminum wheels are POLISHED - it is not recommended. Also - do NOT let it DRY on the Aluminum surface - and be sure to RINSE off - with clean water.

AlumaBright Acid is a must-have for anyone who wants to keep their aluminum surfaces looking their best. Its effectiveness, safety, and ease of use make it a top choice for both household and professional cleaning tasks. Give it a try and see the difference for yourself!

This stuff is AMAZING!! I bought an aluminum horse trailer that had lots of oxidation. My husband used this stuff as directed and we both are so happy with the results. Be sure to use a soft cloth to apply and not one that is abrasive.

Works very well but you may need to adjust the ratio of water to solution. For best results you should spray on and not wipe on.

Good

Makes old aluminum look like brand new. Take out old tarnishing in about 10 minutes

Used for pontoon boat that had about 8 years of freshwater lake build up. Read directions and mixed the ratio and sprayed it on, but it didn't do too much, and just left it really spotted.Increased the ratio each time and ended up using a brass soft brush to remove the build up along the water line. Even then it wasn't coming off. This stuff just seemed to turn the lower half water build up darker. After I lightly used the brass brush on the top half, I used it again and it seemed to foam up right away and made the top half a look half decent, but under the water line it didn't seem to work and I pretty much gave up. It did improve the look of the top sections however, and I was able to lower the ugly water line build up with a sander. I would say, if you have a lot of hard water build up, you Will definitely have to increase the ratio by a good bit to get it to do anything.

Amazing product. Cleaned an old aluminum trailer with no effort. Spray on, wait 4 -5 minute and rinse off. Finish clean like new.
