That is super useful information. Thanks for your contribution.

Rexona do a spray on non-staining deodorant that never seems to stain any of my shorts, not even my gym shirts.

I find the secret is to spray it on, let it dry and then put my shirt on.

I've tried the American model of always wearing an undershirt.  Too hot.

I gently rub in a small amount of Vanish powder, allow to sit for a few minutes and machine wash using pre-soak cycle and wash with cold water. Check stain removing before drying. If the stain is still present repeat.

Individual physiology/diet/whatever must make a difference.  I regularly wear shirts, multi day without any staining.  Even my tramping gear which I sweat like pig in has no staining.

I have the same experience, very little to no staining and I jump between all sort of different brands/products of deodorants (including switching between roll-on and spray) without noticing any differences. I do wear a fresh shirt every day though (although as you say tramping gear I do sometimes wear for a few day at a time and no issues there either). Wash with cheap washing powder (Surf brand and the like) too. YMMV.

So an update to this.

I did an overnight soak in oxi-action, with a bit of a scrub - some shirts required a couple of soaks since it was well ingrained, but it seems to be mostly removing the build up. There are a couple which have dye issues, so presumably just poor quality shirts/shirts have just worn out and need to be replaced. 

I'm trying a different deodorant again to see how we go with that, but suspect it'll just be a process of having to continually go through this soaking process etc. 

I think part of my issue is that I have to do clothes drying inside on an airing wrack, whereas, I recall not having this many issues years ago when i was able to hang clothes outside, perhaps the natural bleaching from the light etc. was helpful.

Either way... making some progress... thanks for all the tips
