Technician Jason Carter says, "I recall a specific case where a customer's front load washer experienced a drainage issue due to a build-up of undissolved beads in the drain pump."
The fragranced oil within the scent beads can also clog the machinery of your washer and leave residue on your clothes, according to lifestyle blogger Sarah Clemence.
Many scent beads contain perfumes that can irritate sensitive skin. Instead of scent beads, add half a cup of white vinegar to your laundry for a deodorizing effect.
