Did my first bud wash today, went with two buckets, first with 200ml of 12% hydrogen peroxide to 5 liter water, I know it's very diluted but did not want to overdo it on my first go. Second bucket clean water, also 5 liters.
Branches were cut and whole branch dunked and drowned in the H202 solution, moved the branches around in the water to 'wash' them, all and all 15 seconds in bucket 1 and 15 in bucket 2.
H202 left, clean water right:

Buds hung to dry, will move them to dark place tonight:
All that is left:
Hopefully it helped a bit, found a couple of leaves with PM, so rather safe than sorry.
