This is great; we have a running experiment. How long have you done this with that pair? Let's see a check-in when they've taken showers for several months- a year.....

I can't see why a mild shampoo would hurt the pearls- it is either Ph balanced or it's slightly alkaline --it's the silk that would have the bad reaction (all the "care for your pearls" posts have more about taking care of the silk when they are washed than the pearls themselves).... but there is no silk in your average earring.

I would think chlorine would be a more of a problem- so much water has a hefty dose of chlorine......but it is alkaline too, so maybe we will need an experiment with chlorinated water and shampoo with a pair of earrings on.....
