Woman's cleaning hack shows how dirty your 'clean' bathroom towels really are

A man has left people grossed out about what might be lurking in their bathroom towels after sharing a photo showing the results of his wife's cleaning hack.

Jared Guynes says he was stunned to see the grime that came out of the couple's freshly cleaned towels and the Facebook post racked up almost 86,000 shares as others vowed to try it out for themselves.

Despite having been through the wash, the photo shows a bathtub of thick, cloudy brown water as Jared warned no matter how clean you think your towels are, they are "probably this nasty too".

His wife had watched a YouTube video about 'towel stripping' for a deep clean, mixing Arm & Hammer baking soda, borax, Oxi Clean, and hot water in a bathtub before letting the towels soak overnight.

Jared wrote: "In this case she took our collection of clean towels, let me say that again, the towels were totally clean, washed and folded and in the linen closet, completely clean, completely normal.

"The story that she told me is that over the years of use, microscopic amounts of soap and detergent get locked in to the fibres of the towels.

“Subsequently that stuff gets gummed up and can also trap microscopic amounts of dirt and grime and bacteria, even after going through the washing machine with detergent.

"So after seeing someone else do it she decided to do the experiment on our own towels here in the tub."

He said he was "literally freaking out right now" after seeing what came out of the towels he had been using and he wasn't alone, as News.com.au.

The Facebook posts gained more than 30,000 comments as people said they: "OMG! I need to clean my towels now!" - as others worried about the state of towels in hotels.

Some argued the mixture had simply stripped the colour out of the towels rather than hidden dirt, writing: "It's a chemical that brought most of the dye out of the towels."

But one replied to say: "I've done it with pure white clothes and gotten this result."

Another commented on the post saying the grime wouldn't build up if towels were washed on a higher temperature, saying: "If you wash your clothing and towels properly each time, stripping is unnecessary and this won't happen. This is what happens when you always wash on 30/quick wash – minging!"
