[Rockhounds] muriatic acid for cleaning...!?????!!!

[Tim Jokela Jr.]

No need to debate this stuff, folks.

The correct answer is that TOTAL BEGINNERS should not be using HYDROCHLORIC 
ACID.

Direct them towards a tootbrush and soap, and suggest that many rocks found 
in the field will not turn from ugly to beautiful  no matter what you do to 
them.
