Thanks for your thoughts. Right now the temp in Maine is in the low '90's and it feels like it could be SW GA! Operative word on the AC solution is "outside". Don't think my wife would go for hosing things down inside!
I'll likely start with low pressure and the vacuum hose nearby and we'll see how it goes. I'll let you know.
Alaska, eh? Southeast was my home for about 20 years. Have to get back some day for a visit. They tell me things have changed; at least until you get outside of town.
