Your boyfriend is right about germs, but that isn't the reason you want to use warm water. The solubility of substances in water increases as the temperature goes up. Using warmer temperatures greatly increases the water's ability to remove polar stains on your hands, and aids in the formation of micelles (of the soap molecules). This helps the soap molecules to dissolve the non polar oils and greases faster.
As for warm water being a breading ground, drying your hands right away and using running water should help with that.
It can, but hot water works better because it helps to dissolve grease and hardened food better than cold.

yes. a hundred times better. Actually not necessarily. Washing by hand works extremely well if done properly. In fact, a company named Dyson in the UK actually designed a washing machine which better imitates the hand washing action to get the clothes cleaner. People tend to assume that just because something is automatic it works better, but this is not always true. Washing by hand does a much better job of flexing the fabric. Of course, it's a lot more work too.
A washing machine works by filling a drum with water, adding detergent, and agitating the clothes to remove dirt. The machine then drains the dirty water, rinses the clothes with clean water, and spins them to remove excess water before drying.
Yes, just put some washing powder into it and it will works.
If you have a large washing machine, they do just fine in one. Usually a commercial one works better than a home one.
What problems does hard water cause? If you wash clothes with hard water they will often look scratchy or feel very harsh. Often if you bathe with soap and hard water you will have a sticky film of soap left on you. If you wash dishes mainly in a dishwasher with hard water you will have spotting or a film on your dishes or cooking utensils. Some things that are convenient about hard water is that it works just fine for watering your garden, washing or rinsing you driveway, and it is fine for most outdoor lawn care things.
A washing machine works by filling the drum with water, adding detergent, agitating the clothes to remove dirt, draining the dirty water, spinning the drum to remove excess water, and finally rinsing the clothes with clean water. The combination of water, detergent, and mechanical action helps to clean the clothes effectively.
The washing machine works by filling with water and rotating. The operator has to put in soap, bleach and softener. The washer agitates, then spins, then fills with water, then rinses by agitating, then drains again by spinning.
No, what really works is slathering your face with cheap makeup and not washing it off for a week and a half
A cloth washing machine works by mixing water and detergent to create a cleaning solution that agitates and cleans the clothes. The clothes are then rinsed with clean water and spun at high speeds to remove excess water. Finally, the clothes are dried either through a spin cycle or by being placed in a separate dryer.
When soap is added to hard water, it can form a scum or residue due to the reaction with the minerals in the water. This can reduce the effectiveness of the soap, prevent proper lathering, and leave a film on clothes or dishes. It may also contribute to build-up in washing machines or dishwashers over time.
