Does anyone know how to remove the built up hard yellow stuff in the armpits of shirts? I have been told it is a deodorant/antiperspirant buildup. It is unsightly and uncomfortable to wear as it is very hard, let alone looks dirty, even if just laundered. Any hints and help is appreciated!

I wear a lot of black. Unfortunately the antiperspirant that works best for me is a white solid kind. As Megan F. mentions, try rubbing the underarm areas with a pantyhose when damp before drying. The texture of the pantyhose works better than anything I've found so far.
I use Mean Green on the underarms of my husband's shirts and it helps with deodorant buildup. However, I have only tried this with white shirts. The spray recommends you test it on an inconspicuous area first if you are in doubt about it discoloring something.
Make a paste of baking soda and white vinegar and place this on damp clothing (area like under arm). Or put white vinegar on shirt then baking soda and add a bit more vinegar till it fizzes, then scrub away and wash.
If you can hang it out in the sunshine, that will help too. They also sell "whitener" the people who make RitDye has these and use in the yellow areas to get the dingy color out.
I had a black polyester Nike work-out shirt that had the white caked anti-perspirant in the under arms. I boiled a full tea kettle of water and poured it through the fabric, then laundered as usual and the build-up is gone now.

How do you remove deodorant residue from t-shirts?
My husband is a professional firefighter who wears navy blue t-shirts under his uniforms. The underarm areas become stiff and extremely uncomfortable due to a build-up of deodorant and the otherwise good shirts quickly become unwearable.
