For Best Results in Maintaining Temperature.
Want to maintain your contents hot longer? The hot button is to preheat or pre-cool your thermos vacuum container. It isn't difficult. Fill the container with hot water or cold water. Allow it to go sit for 5 minutes. Empty and after that refill along with you chosen beverage or food. Avoid using the microwave to heat your thermos vacuum bottle.
Cleaning
First, avoid a couple of the big mistakes. Don't wash it within the dishwasher. Wash yourself. Wash every aspect in warm mild soapy water. Use dishwashing soaps like Dawn or Ivory or another mild dish soap. Rinse clean before using. Harsh abrasive cleaners and scrubbers can damage or tarnish the finishes and interior of your containers. With time, they can even affect the flavors in the stored foods and beverages.
Second, avoid chlorine or bleach. Why? Chlorine and several other strong stain removers attack the rubber gaskets inside your seals and lid. With time, your thermos vacuum contents will quickly leak.
Stubborn stains like tea and coffee are removable. A few teaspoons of baking soda and domestic hot water might be left inside. Let it stand open first hour before rinsing thoroughly. On stubborn stains, soaking overnight produces excellent results. A bottle brush may help.
Some want to use vinegar instead. As opposed to baking soda, they mix 1 part white vinegar 3 parts water. Allow it to go set. The concentration can be stronger if necessary. On all cleaning, be sure to rinse very well with water.
Wash the surface using a soft, damp cloth or sponge and wipe dry. Now use it.
