If you are writing of condensate water - that is, perhaps, some of the least 'healthy' water on the planet.

a) It condenses on (mostly) aluminum that is exposed to (typically) 90% return/10% fresh air. The return air is freighted with whatever is in the house/building/whatever that passes through typically very coarse filters. So, dander, dust, bacteria, grease, and whatever virus is in circulation. The fresh air could have very nearly anything in it.

b) Whatever corrosion exists on the fins becomes part of it.

c) And it drains via channels and/or tubes that could be 'growing' in their own right. Even if anti-mold tablets are utilized, *THAt* chemical is no fun either.

so in summary an ideal water source for irons that boil it in use.

Perhaps over-use of condensate water might explain a great deal in your case?
