A microbiologist has left people horrified after sharing just how dirty a kitchen sink can be, even after it's been thoroughly cleaned.
Tim Call, 32, posted a video on TikTok in which he tested his kitchen sink for bacteria before cleaning it with hot water and soap and testing it again to see how many germs he'd managed to get rid of.
And the results are bad news for germaphobes, as even with a good scrub and some bacteria-killing supplies, the scientist still found a whopping 45,000 original bacteria samples lurking behind.
