Do DIY Cleaning Ingredients Like Lemon Work? A Microbiologist Weighs In

With that being said, using DIY cleaning ingredients can still be effective. Tetro has a few science-backed DIY options that can help keep your home squeaky clean.

1. Vinegar

Vinegar is a well-known DIY cleaning ingredient, and it lives up to the hype. “Vinegar of any form is an effective grease-removing acid and can help to reduce the level of dirt and microbes on any surface,” Tetro says.

Combine it with citric acid (like lemon juice) in a spray bottle to amp up its effectiveness: “The antimicrobial action requires some additional help such as the addition of citric acid, which is known to be antimicrobial,” he adds.

Speaking of lemon juice, it’s an impressive cleaning ingredient on its own. According to Tetro, it can “help reduce the level of microbes on a surface” due to the citric acid it contains. “But in order to get into dirt and grime, it needs an additional surfactant like soap to work,” he says.

There are plenty of benefits to adding baking soda into your cleaning routine. “It’s a great deodorizer and can help reduce the levels of pesticides on fruit. In addition, it does have some effect on microbes,” says Tetro.

When you combine it with vinegar, you have a powerful DIY option: “It would need something to give it an extra punch against bacteria and viruses,” he says. “We all know that adding vinegar sets off a rather violent reaction and this could work. But it’s only for a limited time.”
