We had tw or three days in June and again in July where it was very humid. Heck it has rained three out of four days this summer.
Anyway some wind brought in a load of mold spores and mildew spores but not so much. The woodwork and the wood chairs etc on the porches turned black as did the basement garage door. We used mold armor spray on a hose end and rinsed and got most of it but it left traces in the oak chairs. Will have to do a lot of cleaning with something strong, when we bring them in for the winter. You could smell it in the air it was funky. Changed the air conditioner filters and cleaned everything inside with Lysol. Thankfully it didn't get inside. Will have to check the coach. It is stored inside though.
