So my sister is allergic to sulfur. We found this out one summer when she went swimming in a friends pool that was chlorinated. She breaks out into this rash all over. She has even gotten a small rash from drinking heavily chlorinated water. i heard that cruise ships use chlorinated water in showers/taps, but their pools are salt water. Is this true. It has taken me 6 months to convince my sister to go with me on a cruise and now it looks like she can shower when she's there. Does anyone know if this is legit / or if there is a cruiseline that does not heavily chlorinate water? Has anyone come across this problem?
