Hi I use oxalic acid as a more control but the last couple of times instead of vaporizing it has turned into crystals that completely cover the hearing pan and look a bit like hoar frost. Is this because it's not getting hot enough? Has anyone experienced this and know how to fix it?

Hi Julie,

From my experience you have guessed it... your iron is not getting hot enough. Make sure your battery is fully charged and perhaps do a test run outside of the hive to establish the time required to complete the vaporization. This is usually 2 - 2 1/2 minutes.

Thanks. You were right my battery was going flat. I have bought a charger and it's working great now.
