Bought product mainly to clean/neutralize rusted auto parts. Seems to work great fot that. I removed all scale rust and applied a 3:1 (3 parts water > 1 part phosphoric acid). The rust started dissolve and I eventually was left
with a white zinc residue. I also used it to clean up some lime
deposits on my masonary chimmney. So far this product
works great for a variety of jobs. Nice to have on the shelf.
Yes, I recommend this product.
