Q. Before I decide whether or not to buy Tervis products, I want to know if they really are dishwasher and microwave safe. I know that the company states that they are but I have heard cases of them melting in both dishwashers and microwaves. Can Tervis tumblers really go in the dishwasher and microwave? I have four kids, a job, a husband and two dogs. I really can’t be standing at the sink doing dishes too often and I’d like to be able to use them for heating up soups and other warm drinks.
A. Yes, you can microwave Tervis products, but take care not to do so at too high a heat. There have been some complaints from people who have said their Tervis melted in the microwave but most people do stand by the products and say they have had no issues. If you avoid high temperatures and don’t leave anything in the microwave for too long, you shouldn’t have any problems.
In terms of microwave safety, make sure you follow the manufacturers’ instructions, not only the microwave’s instructions but also those on any microwavable dishes and kitchenware. Tervis products are well made but nothing is indestructible, just use common sense and follow the guidelines that come with all of your kitchen appliances and kitchenware.
With proper care and caution, you should have no issues with any Tervis products in the microwave. Try to stick to 30 second intervals only for any Tervis tumbler and check whether it has a sticker stating ‘Microwave Only When Full’. For those tumblers, a metallic coating inside means that they must be full in order to be safely used in the microwave so that the liquid covers the lining.
Regarding Tervis in the dishwasher, it has been noted that over time, the products can take on a cloudy appearance. It doesn’t make them unusable but can make the appearance dull and a little worn looking. Tervis say that for best results, don’t use the dishwasher too often. As for melting in the dishwasher, just use a low temperature and you should be just fine.
