Cleaning a stainless steel bottle is a subject that raises doubts because, as you may already know, and if not, here we clarify it: it is not recommended to use a dishwasher. Stainless steel bottles have to be washed by hand. We explain in more detail the best way to wash these types of bottles.
Fill the bottle with warm water and a little dishwashing soap, about half full. A few drops of soap will suffice. Then cap the bottle, making sure the cap is screwed on tightly, and shake vigorously for a few seconds (at least 10 seconds). All that remains is to unscrew the cap and empty the bottle, now much cleaner.
You can repeat this process a few more times if you want to go even deeper into the cleaning. To dry it, put the bottle uncapped and upside down in your usual dish drainer.
If you want an even more thorough clean, you can use bottle brushes. They are very long brushes that will allow you to scrub even the deepest and most inaccessible parts of your steel bottle. This method is especially recommended if the bottle has been used for liquids other than plain water (coffee, soft drinks, etc.).
We must not forget the cap, especially if it is threaded. In that case, you can use a sponge moistened with soapy water, rub it on the inside and outside, and try to access the interior areas of the thread.
As you can see, washing a stainless steel bottle is very simple, even though we cannot put it in the dishwasher, as the product could soon deteriorate with such aggressive high-temperature washing for so long.
This type of bottle is so popular because the material is very safe, it preserves the temperature of liquids well, and does not change their taste. It is very common for personal use at home, at work, as well as on trips, excursions, and schools… in short, it is a multipurpose product.
Method 1 of 3: Clean by hand
1. Fill the bottle halfway with warm water and a soapy solution. The easiest way to clean a stainless steel water bottle is to fill it halfway with water and add a few drops of dishwashing liquid. Cap the bottle. Shake it vigorously for several seconds. Unscrew the bottle and pour out the liquid.
2. Rinse and dry the bottle. Immediately fill and empty the bottle several times with warm water. Put it upside down in the dish drainer to dry it.
3. Use a bottle brush. If the mouth of the bottle is too narrow for you to reach the bottom with a conventional sponge, you can use a bottle brush to do the cleaning. This brush is an elongated tool that will be used to clean the deepest recesses of your bottle. These utensils are especially useful if you have filled the bottle with liquids other than water.
- Some stainless steel bottles come with their brush. But if yours didn’t come with one, you can get one online or at your local outdoor supply store.
4. Scrub the thread fillets. If your bottle is a screw cap, it is important to clean the fillets around the mouth. To do this, just moisten a sponge with soapy water and grab the inside and outside of the bottle’s mouth with the sponge. Rub the sponge down the length of the bottle’s mouth several times to clean it.
Method 2 of 3:Use alternative cleaning methods
1. Put your water bottle in the dishwasher. If you have a dishwasher, you can simply put the bottle in there with the rest of the dishes when you’re ready to wash a load. Put the bottle in the dishwasher upside down and uncapped. Also put any removable parts, like the lid or straw, in the dishwasher.
- Add the proper amount of dishwashing detergent, close the dishwasher, and start a regular cycle.
- Before you put the stainless steel bottle in the dishwasher, make sure the product is dishwasher safe. For example, the bottom of the bottle might say, “Dishwasher safe.” Painted or insulated bottles are probably not dishwasher safe.
2. Use vinegar to clean the bottle. Fill the bottle 1/5 full with white vinegar. Fill the rest of it with water. Let the vinegar act overnight. In the morning, throw away the vinegar and water mixture. Rinse the bottle well with water, then place it in the drainer upside down to dry naturally.
3. Use baking soda and bleach to clean the bottle. Add 1 teaspoon of bleach and 1 teaspoon of baking soda to the water bottle. Fill the rest with water. Leave the mixture to act overnight. Empty the liquid the next day, then rinse the bottle well. Put it upside down to dry.
- This cleaning method is effective for very foul-smelling stainless steel water bottles.
Method 3 of 3:Choosing the right stainless steel water bottle
- Look for a bottle with a removable bottom. Many of the newer stainless steel bottles have screw cap bottoms. This way you will have better access to the bottom and inside of the bottle, which could be impossible in bottles with narrow necks and mouths.
- Choose a wide-mouth bottle. Bacteria can hide in the bevels of narrow-mouth water bottles. A wide-mouth bottle will limit the curvature of its internal surface, which will minimize the surface area that bacteria prefer. The interior of wide-mouth bottles is easier to see and access, which will make cleaning easier.
- Make sure the bottle is made of food-grade stainless steel. Not all stainless steels are the same. There are various types of stainless steel alloys. Before purchasing a bottle of this material, check the label or the bottle itself to make sure it is made of 18/8 or 304 stainless steel. These are the two food-grade stainless steel indexes.
