Hi! You consider buying a larger neck sized shirt, so that there is less actual contact with hubby's neck, most men do not re-measure their neck size frequently and still use their old size, when they weight less than they do now. In the military, we use a product called ZOUT it removes, blood, grease, ink, and other stains, I have seen it everywhere, it is expensive, but, the cleaning outcome makes it worth it... Also, the use of Oxi-Clean as a paste, and a small scrub brush at the neck area, is another method to remove stains, plus adding some of this to the wash, really loosens and brightens clothing. Also, you might want to ask your huby when does he apply his cologne, and other hygiene items, because if he is applying after he has gottne dress, the never-ending stain, just might be his colognes, so ask him to "perfume," first, and dress, after the colognes dry, before putting on his shirt, pants, etc. Good luck!
