Don't know why you would need it but...good idea. I have some in those 1 gallon and bigger ones that are new but I am so hooked on the project boxes from JOann's too. The only way I would not use them if it was a project for someone else as many have allergies to different smells. I do this when I get things in the mail from smokers. LOL Works every time. That and fabreeze spray. I will have to watch and see how others feel. Thanks for the great post, fella.:):):)
