I have 13 deer skulls and one elk skull that I have been degreasing and I'm about to start whitening with peroxide. I purchased a gallon of Soft Swim C and it wont be quite enough to cover a skull completely in the small plastic container I plan on using. I dont want to buy more Soft Swim so diluting it will get the volume required to cover the skull. I understand that this will lower the H2O2 percentage and increase whitening time and I'm OK with that. Can I dilute Soft Swim with 3% grocery store peroxide? I want to mix 1 gallon of Soft Swim with two gallons of 3% for a 3 gallon total. This would be 0.275gal + 0.03 gal + 0.03 gal = 0.335 gallons of H2O2 in the 3 gallon total 0.335 gal/ 3gal = 11.2% peroxide Has anybody done this before? How many skulls can I expect to complete with this amount and percentage?
