This is an excellent cleaner. I sand with 320 grit, clean off the residue, and then scrub with this cleaner. After a rinse, its ready for priming or alodining.

Alumiprep is outstanding. It cleans aluminum perfectly. Takes the paint off and makes a much better surface to prime. It is amazing how dirty parts are. Ones that look clean arent. This stuff does the trick, but it is shipped hazardous. It was expensive and slow to receive. Order early if you need it.

In combination with M-CR 1201 this product provided the perfect etching to the aluminum for painting.

Works quickly and thoroughly. Used to prep machined aluminum parts prior to alodine 1201 treatment and the results were outstanding.

Worked great! Had a spider from an older HE3 Whirlpool Front Load washer go bad. Got a good used one that needed a good cleaning. Afterwards a basic wash in C-IC 33 AERO to remove whatever it removes :-) and water no longer beaded, and coated it in enamel to protect against corrosion as recommended by other techs. Well see how long this one lasts!

Worked great for cowling prep. before 1201 alodine and paint, used scotchbrite to apply out on lawn with garden hose, need gloves with this product. 4 stars instead of 5 because of cost seems to get jacked every 2 months.

I haven’t gotten to the point in my project use the product yet. However one issue is the bottle instructions mention diluting the product prior to use. Sadly the bottles label makes no mention of the proper dilution ratio to use. I’m hoping the information will be available online. This isn’t an aircraft spruce problem but more the product supplier.

Worked very well to prep for alodine. It is an acid so gloves and eye protection is prudent.

Product performed as expected & received in good condition. The only thing I would suggest, is if a product is not stocked or out of stock & has to be brought in from a supplier, informing the customer of a delivery date should be done, I had to telephone to find out the date the expected delivery to your warehouse was.

This review is for people like me in search for the magic chemical that will clean heavy oxidation from cast aluminum (transfer cases, engines, etc.). Im sure this product would be a 5 star for airplane painting. For my application I thought this is the killer product that will save me from doing media blasting. It works some but only when used undiluted and using a lot of elbow grease with a wire brush (use stainless steel). I tried it on a small and simple cast part. I was hoping for a good results on this project so I can later use it co clean a transfer case/differential that has too much details to want to scrub by hand. A chemical solution would be ideal. Unfortunately this does requires a lot of scrubbing to get heavy oxidized aluminum bright. To be fair I tried a lot of chemicals and none was great. Actually this is one of the best but still not good enough for the job. Im sure this would be great for painting airplanes used as directed. But Im not paining any airplanes.
