Descaling an Electric Kettle

I wanted to descale my electric kettle and decided to use white vinegar for the first time. Impressive. I was both surprised and pleased at how well it does the job. I let a mixture of 1:1 (v/v) white vinegar and water sit in the kettle. A couple hours at room temperature and descaling was complete! After rinsing with water 4-5 times my kettle is once more back in active service.
