salts ok in pedicure tubs
hi all, preparing to start at my first salon. i have a foot soak, but my salon owner has been teasing the idea of a pedicure chair with the built in tub. ive been toying with the idea of mixing my own soaks, which often have epsom salts/ultrafine sea salt. are these ok to use in foot baths, or is there concern of crystallization? i dont usually do a long soak, and i dump the water when im done like, doing callouses and massage and shit before painting, so itd only be in there for like 20ish minutes. but still, dont exactly want to ruin a nice pedi tub lol in the bucket im using for now, sure, but idk about the nice chair lol
