Residue

In early May I bought a Portable Collapsible Kettle from Amazon. I used it about eight times or so and I really like it. I boil water in it very quickly to make instant coffee, hot tea or hot chocolate. It's really good! I didn't need to use it for about a month, so I dried it up and put on a shelf. I got it out today to start reusing and found some white residue on the bottom metal inside the pot. (See the picture, on the right side is the white residue) I have tried several times to wash it out to no avail. Do you think it will be safe to use it anyway?

I might try a few times and see if it tastes weird.

Boiling it and rinsing it didn't get rid of it like @Ineeddentures suggested. Maybe it got rid of a little. I will try what you suggested too. A combination of them both might be the answer thanks!

It sounds like calcium from the water. I think it's OK.

It's likely lime or calcium scale. Sometimes vinegar can remove it or a product like CLR has to be used. It's pretty common and doesn't normally pose a health risk. As long as you've scrubbed it and rinsed it out, you should be good to go. Enjoy your tea.

Thanks, yes I think my daughter has some vinegar here, but I can't find it. When she comes home I will ask her.

It's hard to say if the water would be safe or not but once it's boiled it should be.

Fill it with water Boil it up Discard the boiled water Then it should be ok to use if you were in any doubt

You know I have no idea. I have an electric glass water boiler I use. I checked online and this is what it says Safety: If the residue is from minerals, it is usually safe but may affect taste. Cleaning: Regular cleaning can help prevent buildup. Use vinegar or a descaling solution to remove mineral deposits.
