I did a test of it and another product called oops and I think they are pretty close in chemical make-up. They both did very well on the chip and both started to Disolve the inserts. I don't know what the difference is in material of the inserts, but be very careful using solvents, because sometimes their effects aren't noticed right away. Months later you may have junk along with anything they were stored next to in a rack or container.
