I don't boil the water, just use hot water and shake the jar until all of the sugar dissolves. I replace the nectar every other day when the temperature is below 80°F/26.6°C; every day when above. If you use bleach (I do not) you MUST make sure to rinse ALL of the bleach off. I just scrub thoroughly with the hottest water I can stand and use a bristle brush to clean the sipping ports.
