Lightening in a bottle: comparison of ultraviolet light to traditional sterilization in saline irrigations bottles.

Cleansing of NSI bottles with tap water with/without detergent or microwave produced robust bacterial disinfection. Distillation and boiling of a contaminated water source completely eliminated all bacteria. UV light treatment was capable of simultaneous disinfection of both the water source and bottle, suggesting this may be a convenient, 1-step method of preparing NSIs for patients.
