Ok, after using both the non-smelling sani solution, and the really smelly solution, I need a different solution completely! I might just be really sensitive but both solutions are very smelly to me, almost to the point I must to leave the house when the machine's going. I've read some of the posts about re-filling, and needing a re=programmable thing - but then it get's into a HUGE technical discussion that I don't understand. Sometimes the post has a defunct website attached.

I need 3 things, I need to make the smell go away - and ideally to make these little crystals from sticking to the cats thus no longer tracking all over the house! I also need someone to share with me where I can get a re-programmable thingy that will work - and can explain how and why it works - to a non-jargon speaking person! Any help out there? ~ Thanks

I've been having people go with a bulk solution and reprogramming their cartridges to a 252 count vs the standard 60 count. With a bulk solution setup, you don't worry about the nipple going bad as quickly as resetting a cartridge to a 60 count. Also with a bulk solution setup, you can easily see how much solution you have left as well as using a solution that works well with yer household. I currently use a 50/50 mix of Dawn liquid soap and hydrogen peroxide.
