NaOH is a super cheap, common chemical. It's the principal ingredient in Drano and similar plumbing cleanout products.
High concentrations of NaOH in water are strongly basic. It will corrode many oxide-based ceramics (like toilet bowls) and aluminum, but it's no problem for most other common metals and plastics.

- philipkglass 10y agoNo, if the sodium hydroxide is already in solution then diluting with copious water is one of the best ways to deal with a splash on skin. You're right that adding water makes the problem worse if you have e.g. a spill of prills to clean up.
- ulrikrasmussen 10y agoI think practical applications would transfer the heat to pure water in a heat exchanger instead of delivering the NaOH directly to the radiator. In a well insulated system, the losses should be minimal
