Renalin is a drug used to improve kidney function and eliminate kidney stones. The term may also refer to a popular kidney dialyzer disinfectant (Renalin 100).
When bleach and renalin are combined it forms a toxic gas. So I would say yes, and to not mix them.
In the United States: It is negotiable and it depends on where you live. In some areas it may be 12.00 US dollars per hour to start. Some states dialysis companues may pay 17.00 to 20.00 US an hour. These days it seems that it is what you can negotiate for.
