I'm try to break down some hard micro matrix from the ATCO formation in TX. Its a rock solid clay, almost sandstone. Now there are some very tiny micros in this stuff and i don't want to cause any abrasion to them by just throwing them in a hydrogen peroxide solution.
Do you guys suggest Muratic acid? Vinegar and baking soda? Or Hydrogen Peroxide?
And what are some ratios you tend to work with? And how long do you soak them?
Any and all help is appreciated by this micro noob!
