expired fina?????

I have some cartriges of fina but its past the expiration date i wanted to know if it loses its potency afta the exp date.........or if the exp doesnt matter or what will happen if i use it....?????? any suggestions...please?

I've heard that the expired cartridges don't work well with dmso. Expired ones must be converted and they're good to go.

IM jus wondering what makes them work when there converted but not with dmso......

So if i take them with dmso they will not work at all??
