Swimming pool trivia...

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.
