The most accessible method for me right now is H2S (in a car, with signage posted). The PPEH says to mix 500 ml of hydrochloric acid and lime sulfur. The lime sulfur is easy, but hydrochloric acid is available in different strengths. What strength concentration of hydrochloric acid should be used for best results? Thank you.
