Sunscreen is a must in summer, but it doesn’t just protect skin. It can also stick to pool surfaces, clog filters, and break down chlorine faster than you’d expect.
☀️ How Sunscreen Affects Water Quality 🧴 Leaves an oily layer on the surface 🧽 Coats skimmer baskets and tile lines 🌫 Can make water cloudy or dull 🧪 Forces chlorine to work harder to sanitize
✅ What You Can Do
Use a weekly enzyme treatment to break down oils
Skim the surface more frequently after heavy-use days
Encourage guests to apply sunscreen at least 15 minutes before swimming
Shock or clarify your pool after party weekends
📌 Bonus tip: Use a tennis ball in the skimmer basket to absorb surface oils.
🛁 Hot Tub Owners: Watch for Buildup Sunscreen residue builds up even in smaller volumes. ✔️ Clean waterline weekly ✔️ Rinse filters more often ✔️ Avoid lotions before soaking
