For muriatic acid: I don't know where you're located but you might 
want to check at a swimming  pool supply or home supply store for 
muriatic acid. It's frequently used for pool maintenance and concrete 
cleaning. It's usually available in a 30% or so concentration in 
gallon containers. 

For hydrogen peroxide: A professional beauty supply store should 
carry the 12% variety which is labeled 'Volume 40'. That's about the 
strongest that I've found.

You may need to find someone with a beautician's license (or convince 
them that you're not going to bleach anyone's hair). The license 
requirement can vary from one store to another.
