Homemade goo gone recipe (the site lists various goo gone hazards... but I bet coconut oil is also hazardous if inhaled! All its safety scores on the MSDS are 0, so not terribly concerned about safety - but homemade is always nice. Not sure about cheaper, though, as coconut oil is fairly expensive!)
I am not kidding you, this works better than the "clinical strength" deodorants Homemade Natural Deodorant. 3/4 C. Baking Soda, 1 TBSP. Melted Coconut Oil & approx 30 drop of essential oil of your choice. Mix and put into a tube.
