The heating element on your dishwasher can be risky when it comes to mugs. The heating element is what's likely to cause most of the problems. Dirty dishes in the dishwasher usually means dirty dishes come out onto your counters, which often leads to a lot of bacteria accumulating on the outside of your cup.
One of the ways of keeping your mugs clean is to always clean your dishwasher before loading it with dirty dishes. Even though you may want to break out your favorite mugs at the end of a long, busy day, you should take a moment and make sure that they're clean first. This can be especially important on washing days when the whole family is in need of a cup of tea or coffee before going off to work.
You should also follow this rule for every cup or mug that you drink from throughout the day. If you spent the morning drinking out of a mug at your desk, you should make sure that it's clean before use. If you like to take your mugs with you to work, it's also very important to make sure that they're clean before placing them in your bag. This is especially true if you tend to drink on the go!
Another way to keep your mugs clean is by throwing them in the dishwasher. Just make sure that you don't let them linger in the washing cycle for too long if you're on a water maintenance plan. And if you do happen to forget about a cup and leave it in the dishwasher for a couple hours, there's not much you can do about it besides run a few extra cycles.
Another tip for keeping your mugs clean is by keeping them in close contact with each other during their time in the dishwasher. If you're having a party, try to keep all of the mugs together as they go through the cycle. This will help to prevent them from "stepping" on each other and picking up dirt or germs. The more crowded your dishwasher is, the more likely it is that you'll end up with clean cups.
If you want to be on the safe side, however, it's always a good idea to hand wash your mugs occasionally. You should do this once every three to four weeks. The reason for this is that a dishwasher just can't get those tiny cracks and crevices of the mug clean. So the best way to make sure that you're getting all of the germs off of your dishes is by hand.
If you're trying to be extra careful, then it might also be a good idea to consider using dishwashing gloves when washing your mugs. These are sold at most grocery stores and come in various sizes. You can also get custom ones that fit over your hands, which is great for cleaning large quantities of mugs that you leave hanging on the dishwasher racks.
Another way to avoid germs on your mugs is by only using them to drink hot liquids. If you tend to use your mugs for tea or coffee, then you should be washing them regularly. This is especially true if you're the type of person who tends to fall into a routine and likes to take their morning mug to work every day of the week.
In which case you might want to find yourself a new mug. It's true that mugs can be put to many different uses, but the smooth surfaces and hard plastic of mugs are not designed for delicate beverages.
With that in mind, it's probably best to use a different cup for these beverages. If you're frequently drinking something warm, like coffee or soup, then you shouldn't be using your mug. Instead, consider finding yourself an insulated stainless steel travel mug for hot liquids. But remember to get these cups washed regularly during the course of the day, just like most of your other cups.
It's also a good idea to avoid putting your mug near a heat source, such as a radiator. Even with dishwasher cycles, you should avoid putting mugs that are close to heat sources. This is especially true if they tend to be used in high stress areas such as offices and cars. Heat can lead to warping and cracking of the mugs and could also lead to some incredibly nasty smells on them.
So, keep them mugs clean, and keep buying more! The more the better!
