I've been bleaching my hands before working with mushrooms, and am getting white spots on my cloths. What is the best way to sanitize your hands before I reach my hands into the moisture chamber to work with the kit?
I think best might be subjective here.
Personally when working with mushrooms / mycellium I wash my arms & hands with soap and water & then put on disposable gloves. I then spray the gloves with a 50/50 water isopropyl alcohol mixture & let the gloves dry before proceeding with my work.
You can use this mixture on your skin too, although it will start to dry out your skin after a while. I do sometimes do this.
A mix of 50% to 70% isopropyl alcohol is a much better choice than bleach. It is less toxic & won't stain your clothes.
