Financial blogs like this usually don’t have recommendations about personal care products, but this one might save you some money. Do you throw clothes away by yellowing caused by deodorants and antiperspirants? Over the years it has really bothered me to toss out a light-colored favorite polo or white dress shirt that still had a lot of wear left in it, but had ugly yellow stains. These clothes aren’t cheap. I was skeptical when a family member recommended an antiperspirant product that I have never heard of called CertainDri. I’ve been using it for several months now, and in this single user test, I have found shirts are unaffected, and I actually perspire less than when using heavy-duty products like Mitchum. The amount of product that is applied is very little, so it lasts a long time, thus saving us more money. CertainDri is unisex, with simple packaging and I believe are all unscented. Pretty limited product line, but I like simplicity. The one my store carries is applied at night, but I understand they have an AM product now.
