Frequently Asked Questions

How long can a high‑quality soup thermos keep soup hot, and does the temperature drop quickly after opening?
A premium vacuum‑insulated thermos typically maintains a temperature of ≥ 140 °F (60 °C) for 6‑12 hours, depending on the initial heat and ambient conditions. Once opened, the soup will begin to cool, but a well‑designed lid (with a sip‑proof spout or insulated cover) can keep it hot for an additional 30‑45 minutes before noticeable temperature loss.
Is it safe to put a hot soup directly into a stainless‑steel thermos, and how should I clean it afterward?
Yes—stainless‑steel thermoses are designed for hot liquids. To avoid thermal shock, pre‑warm the container with hot water for a minute, then empty it before adding soup. For cleaning:
1. Fill the thermos with warm, soapy water and let it sit for 5 minutes.
2. Use a bottle brush or non‑abrasive sponge to scrub the interior.
3. Rinse thoroughly and air‑dry upside down.
If odors linger, add a mixture of water and a tablespoon of baking soda, let it sit overnight, then rinse.
