It is much easier to dilute 30% H2O2 than it is to concentrate the 3% solution. Adding sufficient O2 with the 3% stuff adds a lot of water that is not necessary for the chemistry. Using the 30% H2O2, you can add as much or as little water as necessary to keep the chemistry where it belongs. The goal is controlled etching, and too much water defeats that.

During concentration under vacuum of aqueous or of aqueous-alcoholic solutions of hydrogen peroxide, violent explosions occurred when the concentration was sufficiently high(>90%), [Bretherick 2nd ed., 1979]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: An explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen. To calculate the concentration of a solution, start by converting the solute, or the substance being dissolved, into grams. If you're converting from milliliters, you may need to look up the solute's density and then multiply that by the volume to convert to grams. Next, convert the solvent to liters. Finally, divide the solvent by the solute to find the concentration of the solution
