Thanks!
I have some rainbow vaccum liquid that I put on a cotton ball and suck up into the bag, but the smell is gone by the next day.....
I vacuum pretty much every other day, and the bag isn't anywhere near full, and sometimes it gets that stale smell when you vaccum and I can't stand that, so I end up changing it.
The thing that made me think of Gain is that I have an unopened box of Gain HE powder stored in a room because I bought some that was on sale, and when you walk in the room, it smells awesome in there, so it made me wonder if I put like a tea spoon or so in the bag, if it would work.
Dryer sheets sound like a good idea too.
My main reason for posting is I wanted to make sure the Gain would be something that would slip right through the bag and damage the vac, like drywall dust or something.
Thanks
