I got some new form fitting polo shirts and noticed that my speedstick original stick deodorant was caking up on the underarms of the shirts and not coming out after the wash. You could still smell the strong speedstick perfume on them. So I started researching what causes this. two things cause this. . 1. aluminum in antiperspirant which I don't use so that isn't the issue 2. Stearly Alcohol - http://en.wikipedia.org/wiki/Stearyl_alcohol it seems my speedstick contained Stearly alcohol which is not water soluble and despite multiple washes in the machine it was very difficult to remove since it is not water soluble. To remove stearly alcohol you need to use alcohol, although I had some success soaking it in vinegar and saturating it with shout. took multiple washes to get out. So I am done with any deodorants that contain Stearly Alcohol. Right now I am using white vinegar and two showers a day to control the odor. It does ok but I just can't help but think something might give me longer deodorant protection. I have noticed some body odor under my shirts after wearing, but it washes out right away in the next wash with ease. Obviously the vinegar might not be a long term solution. In the beginning it lasted like 24 hours, now its only good for about 4 hours so not the protection I really need. So I'm searching for a non scented/lightly scented deodorant that doesn't stain the armpits or rub off on the shirt. I've considered the following but each has its drawbacks. 1 - right guard sport aerosol deodorant original - This deodorant goes on fast and dries quick, negatives are boy its got a strong over whelming scent, It was so strong that after removing my shirt the perfume scent was in the armpit fibers. The scent did wash out with ease on my next wash in the washing machine. - note no stearly alcohol or aluminum in it!. Perhaps the right guard sport fresh aerosol would be less offensive? 2 - pinch of baking soda on armpit or building an aquas solution with baking soda in it and something to lower the ph. The drawback I see here is many people seem to have irritation issues using baking soda as the ph of it is like 11 or something obviously way higher than your skin ph of 5.5. 3 - Milk of Magnesia - Milk of magnesia supposedly works great for 24hour body odor protection, You simply dab a small amount under your underarms and wait for it to dry. It drys as a chalky type substance so might rub off on clothes a bit. also my concern is Magnesium Hydroxide is not water soluble. 3 - last but not least considering purchasing the norelco bodygroom pro to trim the armpit hair down to 1/8". Will this help with odor? How low can I go without it being uncomfortable or looking freakish? Perhaps I could just continue using the vinegar if the hair was trimmed down a bit. What are your experiences? Any deodorant choices I am missing?
