    Don’t put them in a case wet, you’ll be sorry.

    Usually a comfortable temp. At home is 70-76er’ and 50% humidity. When you take something outside of that environment into 90-100’ and 90% humidity and high dew point, things tend to sweat or condensation will form. Like on scopes and your spectacles. After a few mins. It’ll go away.

    .

    If the firearm is placed in direct sunlight inside your home for awhile before going outside in high humidity, condensation will not usually form on the heated metal.

    My safes are in the basement at 66-68 degrees F, 49-52% humidity, haven't had a problem yet, but I don't have the luxury of walking right outside with them. A gun case (hard case or soft, doesn't seem to matter) seems to protect them from moisture outdoors; by the time I get to the range they've warmed up.

    Wipe over with Lanotec lanoline .I live in the tropics and have been using this for a while .Comes in spray cans ,I spray it on a cloth and wipe over the metal parts of the firearm .The cloth I use is pretty much soaked and I wipe my hands with it before handling any of my firearms .

    BigEyeBob has a good idea. As I posted elsewhere, the lanolin component of Ed's Red bore cleaner makes it also a fine moisture fighting gun wipe.

    I use Ballistol on all my guns and keep a rag damp with it to wipe down any I take out and do not have sweating issues. Guns are stored in a 68 to 70 degree with 45% humidity room year round.

    After cleaning your guns, give them a good coat of silicone spray and let it dry. Future condensation will sit on top of the surfaces and will not corrode your gun. Let the gun warm up in the sun.

    Wondering about that myself, no sign of sweating in the house but put them in a case and a hot car and go to the range to find them soaked.

    Leaving them in the case in the hot sun makes a mess. I can understand that they are cooler than outdoors but why is it that cased in the heat, they sweat? I suspect the case holds moisture but wouldn't heat allow air to hold more moisture, not less?

    Gun sweat is the same principle as the condensate on a cold drink container.

    My glass half full today! Finally, a no BS benefit for my gun safe being forced to reside in a hot and humid Florida garage next to a saltwater marsh!!! I use a 24" golden rod and small USB powered desk fan and manage to keep the humidity at 51%, but the inside temp is a constant 91 degrees. Most definitely no sweating when I pull them out.

    Veering slightly off topic. Still air tends to lead to rust growth, should rifles be stored with the breach open to encourage better circulation through the barrel?

    I keep my guns in the safe with 2 Damp-Rid dehumidifiers on the floor of the safe. I live on the beach in Long Beach WA. Have never had a Humidity problem with any of my guns. I wipe them with Otis CLP wipes after cleaning before putting them back in the safe. No problems with humidity with my guns in the Gun case when headed to the range.

    If you have trouble finding lanolin, Bag Balm makes an acceptable substitute.
