Identify What You're Seeing

A greasy scum line behaves differently than metal staining. Oils smear, metals tend to discolor more uniformly, and organic stains often lighten with chlorine.

Daily and Weekly Habits

Small routines beat big scrubbing sessions.

  • Skim and brush the waterline weekly
  • Rinse swimsuits (detergent residue contributes)
  • Keep pH stable to reduce scaling and stain risk
