Howdy folks. I use my Dad's issue helmet for various outdoor activities. He passed away a few years ago and I kind of want to keep it in good, original nick. So replacing things here and there is out of the question. (Although the helmet cover is ok, and I do replace that occasionally) Trouble is the interior. It's getting a little.... whiffy. I give it a good spray of anti-bacterial agent every so often, but that doesn't stop the smell. What is the best method for giving the leather padding a good clean? It doesn't seem to want to come out without a fight so I'm not trying. Any other tips on maintaining the helmet in general? Also, how the heck did you go about attaching it to your webbing when not using it? I've seen plenty photos of Dad and mates while on exercise and they have them some how attached so that their ammo pouch is covered by it.
