I can always tell if the pool has been given an extra dose of chlorine that day.
My silver rings turn blackish
Pool water reacts with the ring to create a coat of silver chloride, which darkens as light breaks it down into elemental chlorine and metallic silver.
A good brushing with Colgate takes care of this matter.
My hair turns really stiff and coarse
Showering before entering the pool usually helps to lessen the drying effect.
While a good shampoo should help clean the hair.
However, there are many other tips that will help as well.
