How hot does water have to be?

To sanitize equipment/bottles?

Food industry uses Food Code 1995 as the standard for that kind of thing which dictates immersion at a temperature of at least 170*F for 30 seconds for manual operations.

would it still work at about 150 for longer than 30 seconds say like 10 mins? i wish i had a dishwasher but in okinawa the houses are few and far between that have them but my hot water gets a little bit over 150 degrees.

Short answer;no. Pasteurization doesn't happen till about 162F. Hence the standard of 170F for sanitation purposes.

+1. It will kill some stuff, but not everything, so it might prevent contamination spoilage, or it might not. Different microbes have different thresholds for heat. 150 will kill some, 160 will kill some more, 170 will ensure most (at least most of the ones that you should really be concerned about) are dead.
