I've used oxi on BC chips with good results but there was a recent thread about it destroying ASM's.
Be careful.
& use only cold or tepid water

Edit II : and make sure the oxi crytsals do not come into contact with the chip.
I have had small white dots appear on previously colored areas if too much oxi was in the brew.
If not fully disolved and still floating they may come to rest on the chip and/or your chips may be sitting on top of them .
I use a small strainer suspended in the oxi-water after the surplus undisolved amount had settled.
I like using the oxy-brew after I use an ultrasonic cleaner. Great results.
