I recently purchased a small bottle of Naval Jelly and applied it to some
lightly rusted sink legs. It did nothing. I remember using it about 20 years
ago on the hood of my white 1972 Buick Skylark and it worked wonderfully.
Have the manufacturers weakened this product?

Thanks,

I also think it is of dubious value. I had to switch to using wire
brushes.

Being just a gel of phosphoric acid, it might be in any concentration they
make it. Can't answer your specific question.
However, I found it useful in removing calcium deposits on sinks or other
mineral deposits. But the trick is to give it time.

I only wish they made it in a clear base..........
