I use the Muriatic Acid, Hydrogen Peroxide mixture with 12% Peroxide from a beauty supply store with good success. If you do not want to use the HCL, another solution that is sometimes used is a mixture of Hydrogen Peroxide, Vinegar, and salt.

But mixing vinegar (acetic acid) and salt (sodium chloride)  results  in HCl  !  Just another way of generating a weak solution of it. !
