Hello, fellow PCB makers,

I'm new to the etching community, and most of my learning has come
either from here or other places online.

I've made 3 successful boards so far using the Toner Transfer method and
Muriatic Acid with hydrogen peroxide, but I'm worried about a critical
step:

After removing the etched board from the etching solution, I dried it
with a paper towel and then cleaned it with acetone. Am I at risk of
creating small particles of the friction-based explosive Acetone
Peroxide because I didn't first rinse the etched board with water?

Without knowing about this accidental byproduct beforehand, I've already
soldered components onto the board and added a layer of epoxy to the
bottom as a sealant.
Because this board is going to have to take a lot of vibrations (it's a
quadcopter controller board), should I trash it to e-waste and start
over?

Lastly, has anyone had any bad experiences in accidentally making
acetone peroxide on their PCBs using HCL, H2O2, and Acetone?

Thanks everyone!

Sincerely,

Poofjunior
