Thought I'd put this question out there for the community. Can anyone recommend an effective deodorant that doesn't end up darkening/bleaching or otherwise discoloring the armpits of shirts (especially light colored ones is where it's most noticeable).

I know mostly the reaction that causes this to happen comes from washing in hard water. When I lived in Vegas (the water was so hard there it was awful) I literally stopped buying white or light colored tops because within a few months the armpits had yellowed or grayed.

I've had the same problem in SoCal (although the water isn't nearly as hard) and just recently had to turn a gorgeous Thomas Wylde pale gray fluid top with amazing acrobatic skeletons trimming the collar and hem in to a DIY hacked muscle shirt because (I'm assuming) deodorant caused the underarms to get bleached out (even though this top was dry clean only). It was either that or I just had to throw it away or donate because the bleached out underarms were so noticeable.

For the record I use just basic Secret solid deodorant. Has anyone else had this issue and what did they do? I've got some rather pricey tops that I'm gonna be pretty miffed if they end up looking ruined after only owning them for a few months (and this isn't helping with my desire to wear more lighter color palettes!).

Any advice or ideas are greatly appreciated!
