Causes of Mold
There are four conditions needed for mold growth: mold spores, temperature, moisture, and mold food. There are two main problems with mold, and they are illness and pests. Some people can become ill or allergic to mold and this is an unhealthy way to live. Even worse, mold attracts the likes of pests like cockroaches and other insects that you don’t want in your home. If you did, you’d need to call in https://www.pestcontrolexperts.com/, but there are ways to prevent something like this from happening so you don’t have to resort to this. Mold spores are airborne and found everywhere in small amounts, and cups are typically stored at room temperature, so there’s not too much you can do to control those. The most effective ways to prevent mold from growing in your children’s cups is to properly clean them to reduce trace foods, and more importantly to eliminate all moisture after cleaning.
Travel valves slide to close the straw off to prevent leakage when stored in a bag for travel.
Travel valves are often difficult to clean. They trap water and food particles, and can harbor grime and mold, and then transfer that to the straw they’re covering.
Basic Steps for a Mold-Free Cup
Sippy cups are notorious for their tendency to harbor grime and mold, especially in straw valves and travel valves. These tips will help you get your children’s sippy cups cleaner and stop mold from growing.
1. Wash the cup immediately after each use.
2. FULLY disassemble the cup. Moisture and food collects in the joints between parts, and is exactly the type of place where mold can grow. Separate all straws, valves, rubber rings, plastic sliding covers, and so on.
3. Pre-rinse straws, valves, and other parts that collect food with warm water. Most rubber valves can be opened by pinching with your fingers. Pinch the valve and run water through it to pre-rinse.
4. Wash by hand in warm soapy water, or by dishwasher.
5. Shake out remaining water from all parts. Shake out any water collected inside straws. If your cup or straw has a rubber valve, pinch it open while you shake to get the water out.
6. FULLY dry all parts before assembly. This is a key step, since moist parts won’t dry once assembled. Consider storing the cup disassembled, and assemble only when ready to use.
Advanced Steps for a Sparkling, Mold-free Cup
1. Use a straw brush to scrub inside straws.
2. Use a straw brush or a toothpick to scrub inside valves.
3. Weekly or monthly sterilization may be used to keep your cups extra clean, especially if you hand wash. Some of the more popular sterilization methods:
a. Washing in a dishwasher will sanitize, and some hotter dishwasher cycles can even sterilize. The dishwasher is often the best solution for keeping your cups extra clean without exposing them to excessive temperatures and harsh chemicals that can deteriorate plastic, rubber, steel, and paint.
b. A steam sterilizer is effective for killing mold. As with all methods, you must ensure that the parts are fully dried afterwards, so use the dry cycle if available.
c. A diluted chlorine bleach bath (typically 1 tablespoon of bleach per gallon of water, soak for 2 minutes) is effective, but requires some precautions:
i. Never mix bleach with ammonia, vinegar, hydrogen peroxide, or other household cleaners, can produce toxic fumes. Follow the link for more info about handling hydrogen peroxide safely.
ii. Open windows when using bleach. Bleach is a chemical irritant. It can irritate the lungs and mucous membranes. In its concentrated form, it can damage skin, eyes and clothing.
iii. Thoroughly rinse and dry all cup parts afterwards.
d. A vinegar bath can help to clean grime, but isn’t effective enough to meet the technical definition of sterilization and will only kill about 70% of the mold.
