I want to set my self behind the 2 others. I am learning washing now for about one year. My Teatcher (guru and dukun) usses his hands in the solution and does it inside his house and use a hair dryer to heaten the blade and the solution(
THIS IS NO ADVISE!!!!). He is washing for...i dont know lots of years. He tels me that he knows when he has been to long in the arsenic, dont laugh..his balls start to tingle
.
The temperature is the most important(sun light not needed, can be used to heat the blade and solution) it works as a catalist to start the reaction. The As2O3(arsenic trioxide) is more toxic than the realgar/arsenic sulfide(AsS). I use both. But always never to much safty..to less does exist..you get sick and if your realy are unlucky you can die. The LD50 dose of AsO3 is about 100mg oraly taken. Wounds on your hands and the vapor off the heated solution are the biggest dangers. Use medical gloves iff you want to be sure....and when your balls tingle...get out of there
