Crunchy deoderant armpit stains

[SlightlyMadSpider]

Anything I can do to get rid of the crunch bit deoderant leaves behind after washing?

Or are my clothes too old?

what deodorant are you using?

dehair, roll on + let dry before dressing = no problemo

I use Sure or mitchem roll on.

But it affects DPs clothes too and he uses aerosol.

And I do tend to use deoderant whilst still in PJs. My T-shirts are just as badly affected.
