The Colorful Concern
Bath bombs add luxury and fun to bathing, but many worry about potential staining. Some can indeed leave residue or discoloration, depending on ingredients and tub material.
Ingredients Matter
Natural colorants like herbs or flower petals are less likely to stain than artificial dyes. Vibrant colors, especially blues and purples, have higher staining potential. Oils can leave a slippery film if not properly rinsed.
