Default Rust Dip

Last week, I finished tweaking on the rear end. I had replaced the stock spring, left wheel bearing assy, side yokes and dropped the rear ride height with 9" bolts. I still needed to bring the camber into spec so I raised the rear and tried to adjust my fancy adjustable strut rods. Rust had rendered them non-adjustable. I tied a baggie up around the rod end and poured in enough CLR to cover the frozen threads. After about 30 hrs, enough of the rust was eaten to allow a large pipe wrench with 3 foot cheater to break the screeching thing loose.
I believe it is the phosphoric acid content in CLR that works for eating rust so next go around I'll go to a janitorial supply house and get some bulk tile cleaner with a high phosphoric acid content instead.
Caution : This stuff will eat plating of any kind and paint. It will also eventually
pit any metal, but is a lot easier to use than Navel Jelly IMHO.
I used a considerable amount of anti-seize on reassembly.

I've used Captain Lee's Rust Away which also contains phosphoric acid. It works VERY well. I think you've hit on the magic ingredient. Naval Jelly contains phosphoric acid as well. Let us know how your experiment with the janitorial cleaner works out. I'm interested.

The total fix for this ever happening again, is to pull it all apart and coat the threads with RTV....rubber....silicone seal....run them in and out a bit, and the secure-locking nuts too.....adjust and install as normal...and then forget about it....
