Leave on full for 1 minute or less, so that it's hot but not boiling.

No. As long as there's 2-3mm of liquid over the pcb, any resonances in
the copper are sufficiently damped by the liquid conductivity that there's
no problem with HV arcing.

The resist doesn't strip straight away. I take the tray out and rock it
for some agitation and the resist starts coming off a minute later.
Turn the pcb over to do the other side too.
