You might notice a bit of residue following your bath, especially if you used oils or ingredients that don’t dissolve (I’m looking at you, ginger). Simply sprinkle a bit of baking soda in the tub and give it a good scrub. Then turn on the shower and rinse everything down the drain. I recommend doing this every time you use oils in the bath so that you or your partner don’t get a slippery surprise next time you climb in the tub.
