Nickel stripper
Three dips in the solution, no more nickel on my Thompson receiver. Like the instructions say room temperature (80 degrees) is good, 90 degrees is better, 100 degrees is better yet.
Works exactly as advertised.
We have a batch of hundreds of brass parts with an internal female thread that were electroless nickel plated. No masking on the threads, so they got plated and the threading tolerances got thrown off. Hand tapping them required a specialty tap, was incredibly difficult, and dulled the taps like crazy. We filled the holes with this stuff and let it sit for a few hours. Remove stripper, clean with water, done. It ate the nickel and didn't mess with the brass threads. Absolutely perfect. Saved SOOOO much work, time, and money.
Just used on a Reg. Mag
I mixed the chemicals as stated with distilled water. I mixed half of the chemicals with the water and soaked the Smith for about 6 hours in 85f air temperature. All nickle that I could find was gone, but the polished metal underneath looked like nickle so I let it sit overnight. The gun had two small springs that could not be removed, but the process loosened the nickle so that I could remove the screws that were too tight before I soaked it. The spri ngs were fine after the soaking. Also, I pre-treated all metal with a crud cutter product that is a degreaser and then rinsed with regular water. I have posted treated the metal with a light oil and I will be sending it off for finishing. Also, I mixed the second half and placed it back in the orginal containers for use another day!
This product works!
I used Brownell's nickel stripper to remove the nickel plate from a 35 year old Colt GM slide and receiver in 40 minutes (80 degrees).
