First there was anti-bacterial soap and now anti-bacterial gym chalk?! Anyone used PrimoChalk - the new anti-bacterial gym chalk? From their website: Anti-Bacterial Chalk For Weight Lifting, CrossFit, Gymnastics and Rock Climbing | Primo Chalk [quote] Anti-Bacterial Chalk For Weight Lifting, CrossFit, Gymnastics and Rock Climbing In PrimoChalk™ we've combined quality hand chalk (magnesium carbonate) with a blend of five key essential oils and an additional natural drying agent to create better training chalk. PrimoChalk™ has been tested by coaches and their athletes. The feedback we get is the same from almost everyone who uses it. These are the feedback highlights.[LIST=1]

Fewer Tears and Rips

Better Grip

Less Pain

Longer Lasting

Leaves Hands Feeling Better * Designed to inhibit bacteria, fungi and virus growth in the chalk and on weight lifting and gymnastics bars, PrimoChalk™ is the superior choice for health and safety conscious coaches and athletes. The same organic essential oils in PrimoChalk™ have been university tested for their effects against unwanted microorganisms including icrococcus luteus, Pseudomonas aeruginosa and Staphylococcus aureus. [/quote] The chalk in the chalk bowl or chalk bucket - whatever you use in the gym - can get wet/damp, kind of like fluffy playdough, but that's when you should have already replaced the chalk in the bowl, so the additional drying agent in the chalk wouldn't really apply there. Do you want dry chalk on the bars though? We do water spraying on the bars to have it a little wet as you see most do on the nationally televised gymnastics competitions. Some of us even ocassionally spray the chalk block directly when it feels dry, besides the gym grips. Perhaps it is better used for the other 3 uses they have listed - weight lifting/power lifting, cross fit training, and rock climbing.
