Regular dish soaps contain harsh chemicals and toxins that aren’t safe for your baby. They can leave trace amounts of these on the bottles that your baby could end up ingesting with their milk. Even regular dish soaps that are non-toxic and safer may not be the best choice for your baby’s accessories. This is because breastmilk and formula can leave behind milk fat that regular soaps can’t clean very well. Soap that’s specially formulated for baby bottles contain ingredients that help to get rid of this milk film.
