PM everywhere just before harvest - H2O2 bath, anyone ?

I noticed too late in flowering PM, so decided to let it run anyway to see if I could save something from it..

My plant is now almost completly white, expect the main tops colas, but I don't expect too much from it anyway...

Anyway, I plan to do a H2O2 bath tomorrow to see if I can at least save something.

I bought H2O2 @ 17.5%, do you think it's ok with that ?

More over, I would like to know if some of you here tried it, and if it worked well for you ? Was it only a few PM you had, or your plant was heavily infected as mine ?
Then, after the bath, did anyone went to do some testing on the buds or had a really deep look with microscop or something similar to make sure no more PM would be left on the buds ?

Sorry I tought I was on the Problems subforum, seems I can't move the thread now

Yes I saw subcool execute this method with peroxide and water and decided to give it a try. It really didn't seem to work for me. Very little pm came off and I dipped and scrubbed and everything. Perhaps I did something wrong. But no luck for me. So I wound up cutting off all leaves and I eventually wound up taking a cloth and tediously tried scrubbing each individual bud I could. That worked to an extent cause I smoke quite a bit of it and no side effects.
