In fact, their video proved that when it comes to disinfecting toilets, or any hard surface, most people are making one major mistake.

Earlier this week, The Big Clean Co — a professional cleaning service out of Melbourne, Australia — created a TikTok to demonstrate for viewers how to properly disinfect a toilet.

“So you think you’re a clean freak,” the video’s creator says as they begin to spray down a toilet.

As they go about their cleaning, they go on to explain that there’s a “hard truth from a professional cleaner” that they believe viewers need to hear.

“Just because you’re using a disinfectant spray,” they say, “does not mean you’re disinfecting anything.”

According to those at Big Clean Co, disinfectant sprays need to sit on a surface — in this case, on the surface of a toilet — for 10 minutes before being wiped off in order to kill germs.

“You need to read the labels,” they add.

The video has received more than 600,000 views and 26,000 likes.

Some commenters were skeptical, but as it turns out, the research is on their side.

Last year, Penn Medicine released simple guidelines for properly disinfecting surfaces. They first explain that simply cleaning a surface is not the same as disinfecting one. By cleaning a surface, a person is only “removing dirt and particles” from that surface. Disinfecting a surface kills viruses and bacteria.

According to the Environmental Protection Agency (EPA) via Penn Medicine, disinfecting products should sit and remain wet on a surface or object for 10 minutes in order to properly kill 99.9% of germs.

Even Lysol’s website instructs customers to allow products to remain wet and on a surface for 10 minutes in order to effectively prevent the spread of norovirus.

Many viewers were shocked to discover they hadn’t been properly using their disinfectant sprays.

“Well, this did amazing things for my anxiety,” said one. “MY HOUSE IS A CESSPOOL!!”

“So you’re telling me,” commented another," my toilet I cleaned thoroughly today is still dirty??"

The Big Clean Co jokingly responded: “Yeah I’m saying for sure don’t lick it.”

Though the company demonstrated its point by cleaning a toilet, Penn Medicine reminds readers that other surfaces and objects that require disinfecting — especially for those wanting to prevent the spread of the coronavirus — include table surfaces, doorknobs, faucets and light switches.
