Heat Sanitization: An acceptable method of hot water sanitizing is by utilizing the three compartment sink. The final step of the wash, rinse, and sanitizing procedure is immersion of the object in water with a temperature of at least 170°F for no less than 30 seconds.
Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins). Boiling is not sterilization and is more accurately characterized as pasteurization.
Bacteria and Germs: Hot water (typically above 140°F or 60°C) can help kill bacteria and viruses more effectively than cold water. This is particularly important for sanitizing surfaces and utensils. Cleaning Power: Hot water can dissolve grease and grime more efficiently, making it easier to remove dirt and stains.
Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). During emergency situations, use bottled water or water you have properly prepared and stored as an emergency water supply. Boil water, if you do not have bottled water.

Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water to a rolling boil for at least one minute.
Non-food contact surfaces like walls, ceilings, floors, and doorknobs exteriors still need regular cleaning. However, these surfaces do not need sanitizing–but you should consider creating a regular disinfecting schedule for non-food contact surfaces.
When water is heated, its molecules move faster due to the high level of kinetic energy in them. Higher kinetic energy makes hot water an effective solvent. The higher the kinetic energy in molecules, the faster they will agitate the surfactants. This makes the stains come off much easily.
Temperature — generally chemical sanitizers work best at temperatures between 55°F (13°C) and 120°F (49°C). (See manufacturer's recommendations for specific temperatures.)
The Best Way to Clean Clothes
To kill the germs in your laundry, wash your clothes on the hot cycle, then put everything in the dryer for 45 minutes. Wash whites with bleach, and use peroxide or color-safe bleach for colors. Do your laundry in water that's at least 140 F to kill any viruses or bacteria.
Heat Can Kill Germs
1 But typically, the temperature necessary to kill pathogens, such as dishwashing water, is too hot for our hands to handle. According to the FDA, a temperature of at least 160 degrees Fahrenheit is best for washing dishes if your goal is to sanitize them with the heat.
But boiling water for sterilization has certain limitations. It will not kill many bacterial spores, such as tetani, gas gangrene and anthrax bacilli. It does not penetrate well into dirt, blood clots, and other protective ma- terials which may harbor microbes.
Well, leftover moisture can be a breeding ground for bacteria and mold, and that's definitely not what you want for your baby. Do baby bottles have to be completely dry before use? Absolutely! That's why making sure those bottles are thoroughly dried is key.
How to disinfect water by boiling. Bring tap water to a solid boil. Once the water is steadily boiling, continue to boil for one full minute. Allow to cool.
Specific temperatures must be obtained to ensure the microbicidal activity. The two common steam-sterilizing temperatures are 121°C (250°F) and 132°C (270°F). These temperatures (and other high temperatures)830 must be maintained for a minimal time to kill microorganisms.
Cleaning should be performed regularly and always comes before sanitizing or disinfecting objects and surfaces. Sanitizing reduces the number of germs on objects and surfaces to levels considered safe.
Any surface that touches food, such as knives, stockpots, cutting boards, and prep tables, must be cleaned and sanitized. To clean and sanitize a surface, follow these steps. Scrape or remove food bits from the surface. Wash the surface.
Regular disinfection of surfaces, utensils, and equipment is critical. FDA guidelines stipulate that staff clean and sanitize equipment after each use to ensure food safety. The minimum hot water temperature for sanitizing is 160 degrees F.
Our results show that the practice of boiling in the study community significantly improves the microbiological quality of water, but does not fully remove the potential risk of waterborne pathogens.
Put on protective gear when diluting or using bleach as it irritates mucous membranes, the skin and the airway. Cold water should be used for dilution as hot water decomposes the active ingredient of bleach and renders it ineffective.
In its medical literature, the Food and Drug Administration states that hot water comfortable enough for washing hands is not hot enough to kill bacteria, but is more effective than cold water because it removes oils from the hand that can harbor bacteria.
A disinfectant, such as chlorine bleach, added to your load does a much better job getting rid of pathogens. Still, hot water can't hurt. Use the warmest water setting the items can take, and wash them according to the maker's instructions.
Bacteria and temperature
Generally, temperatures above 149°F (65°C) are effective in destroying most bacteria, while temperatures above 165°F (74°C) are even better and can eliminate a wider range of potentially harmful bacteria.
