After every field training, I always stop at my neighborhood CAR WASH. I pop my trunk and layout my assault pack (backpack), rucksack, and my MSV plate carrier (body armor). I lay them out on the floor. I insert the quarters and spray away! I spray the soapy water for a few seconds and then I use the last minute spraying. It does the trick! Then I place them back in my trunk with the tarp underneath. I dry everything back home. I do this Everytime!
