I am looking for some piranha clean formulas. SPS produces glass and quartz wafers and we do not want to damage our surface finishes, yet we want to be able to remove the microscopic traces that we have found. Can someone recommend a recipe that they have had good luck with? Or perhaps a source for multiple recipes that I could experiment with? Any help would be appreciated.
