I have an empty prelubbed cleaning patch container that I put about 30 - 50 patches in,soaked the and rang them out an I leep them in there.
On some of the higher profile gig's I play we are isseud laminates for all acces back stage so we can move through security without hassel.
These laminates are put in a ziplock type bag with a triple seal (some of the laminates are not laminates we just call them that)
These little bags a perfect for keeping some prelubed cleaning,alcohol etc patches in my hunting pack for field use.
They wont leak
