I cut any bud rot out to an inch of healthy tissue, then wash in 1/2 cup of peroxide in 5 gallons. Leave the buds soaking for a good 3 minutes then do a hot water bucket rinse then cold water bucket rinse. Hang in front of a fan for a good 20 mins or until buds aren’t dripping then trim.
If it’s healthy bud no mold or pm then I only use 1/2 baking soda and the juice from 1 small lemon instead of peroxide.
