Don't use arm&hammer baking soda, it's been proven to have aluminum in it and they don't address it in the packaging. Look for ingredients at your local co-op/natural health store. Also you don't have to use essential oils, it can just be a neutral smell (I make my own similar to this recipe but I can't use coconut) so you won't stain clothes
All of the Baking soda any brand has metals in it. Baking soda absorbs metals, period. It will absorb all the metals from the machinery used to process the Baking soda. Any brand, period. Even if they say they have 0 aluminum. They can say 0 aluminum because they aren't adding it as an ingridient, but being extracted from the machinery used, they don't have to say that. So all companies are guilty. There's no way going around it. Unless you don't take it at all. Just make sure you are having a yearly metal detox and you'll be fine, dont stress. Stress about little things can also lead to health complications. Take care
