So, you've just washed your glass or plastic bottle and discovered that it's still wet inside. No problem! There are many ways to dry the inside of a bottle quickly. Of course, each method has its own benefits and drawbacks. I'll discuss them in detail below:
Use a towel to dry the inside of the bottle.
If you have a paper towel handy, use it to dry the inside of your glass or plastic bottle.
If you have both a towel and paper towels available, use them both in tandem to speed up the drying process.
Next, take a coffee filter and wipe the inside of the bottle. Make sure that you do this quickly so you don't leave any moisture behind on the glass or plastic. As with wiping it with a paper towel, this process should be done as little as possible to avoid leaving scratches on your bottles' surfaces. It's also worth noting that doing so will not get all of the dust off (but it may help).
It's important to note that while drying out your bottles after cleaning them is good practice, doing so too often can cause more harm than good. The best way to dry out glass bottles is simply by putting them in direct sunlight for a few hours until they're completely dry; however if there aren't any sunny days where you live, using hot water instead will also work just fine.
If you want to take a more natural approach, you could use a coffee filter and chopstick. This method will work for glass bottles as well as plastic bottles.
If you're in a rush and do not want to wait for the water to evaporate naturally, use a blow dryer set at low heat. This should speed up the drying process and help dry the inside of your glass or plastic bottle quickly.
Rubbing alcohol is great for drying out your bottle because it evaporates quickly, and you can get it in most pharmacies or grocery stores. It's also very cheap, so if you're looking to save a few bucks while doing this experiment, rubbing alcohol will be your best option.
When using rubbing alcohol to dry out a bottle that has been submerged in water, be sure not to overdo it—you don't want to use too much of the liquid because that can cause damage or even discoloration (the color will change).
You can also just leave your glass/plastic bottle alone. This is the most time-consuming method and is best for glass bottles. You may have to wait a few hours before the moisture evaporates naturally, but it will happen eventually!
So there you have it, seven different ways to dry an inside of a glass/plastic bottle quickly. We think that the best way to choose which one is right for you will depend on what materials are available to you at home and how much time you want to spend drying out your container. If speed is important, try using a blow dryer on low heat or rubbing alcohol!
