FAQs

What is the capacity of this food jar?

This specific model has a capacity of 8 fluid ounces (approximately 237 ml).

Can I put soup in the YETI Rambler Food Jar?

Yes, the food jar is designed for all food and liquid types, including soup. Ensure it is not carbonated or a type that ferments.

How long does it keep food hot or cold?

While YETI products are known for excellent insulation, the exact duration depends on ambient temperature and how the jar is preheated/pre-chilled. Generally, it keeps food hot for several hours and cold for many hours.

Is the lid truly leakproof?

Yes, the MagVent lid is designed to be 100% leakproof when properly sealed, allowing you to transport it without worrying about spills.

Can I put dairy products like yogurt in it?

It is not recommended to store dairy products, especially those that may ferment or build pressure, in the food jar. Use it for non-pressurizing food and liquid types only.

Is the exterior coating durable?

The exterior is coated for durability, but like any painted product, it can be scratched or chipped with heavy use. The stainless steel underneath remains resistant to rust and punctures.

How do I clean the MagVent lid mechanism?

The two-piece MagVent lid can be taken apart for thorough cleaning. Wash both pieces with warm, soapy water and ensure the vent area is clear of any food particles.

Troubleshooting

Lid is difficult to open

Ensure the MagVent lid is not used with carbonated, dairy, or fermenting items. If used with appropriate foods, check that the two-piece lid is properly aligned and the vent is clear of debris.

Food not staying hot/cold as expected

Preheat the jar with boiling water for hot foods or cold water for cold foods for at least 5 minutes before filling. Ensure the lid is tightly sealed.

Interior is stained

For stubborn stains, create a paste of baking soda and water, apply to the stain, let it sit for a few hours, then scrub gently and rinse.

Water inside the vacuum insulation layer

This indicates a seal failure and the product may need to be replaced. Contact YETI customer support.
