This $4 non-toxic glass and mirror cleaner delivers a streak-free surface every time, without harsh chemicals

Since moving into my home with my allergy-prone partner, I've made it my mission to achieve streak-free cleans on my reflective surfaces without using toxic substances.

Thankfully, in 2025, there are many ways to make a home less toxic. And switching over to planet-friendly cleaning products, like Method's Mint glass cleaner, is just one of the ways.

Over the years, I've tried many different cleaning solutions. But nothing has cleaned my mirrors and windows as well as this kinder-to-allergies cleaning product. To discover more, I spoke to a non-toxic specialist and professional cleaner to find out what makes this product so brilliant to use.

Why I love Method's minty fresh glass cleaner

Another person who swears by Method’s glass cleaner, describing it as one of her 'core products', is Sofia Martinez, founder & CEO of Sparkly Maid Austin.

'It’s effective, smells fresh without being overpowering, and aligns with our eco-conscious approach,' the professional cleaning expert explains.

Plus, Method's glass cleaner has also been 'green-rated' as it was rated a 'B', by the non-profit, Environmental Working Group (EWG), which shines a spotlight on practices and industry loopholes that pose a risk to our health and the health of our environment.

'For the best available cleaning options, we recommend choosing from green-rated (A or B) or EWG VERIFIED products found in our Guide to Healthy Cleaning,' says Samara Geller, senior director of cleaning science, consumer safety science.

• It's easy to use: You simply spray on Method's glass and window cleaner (sparingly) and, using a microfiber cloth, like these five-star rated Multi-Surface Microfiber Cleaning Cloths from Target, wipe your reflective surfaces down.
• It's affordable: Costing less than the average cup of coffee, Method's cleaning spray comes in a reasonable 28-ounce bottle, which will last ages, too. The usual RRP is around $9.99, but it is often on offer at a third of the price.
• It's green-rated: According to EWG, Method's glass cleaner scores a B overall, which means it's classed as 'green-rated' according to the non-profit. Deciphering some of the ingredients, Samara says: 'Sodium carbonate is a safer ingredient with low concern for human and environmental toxicity. Similarly, alkylpolyglucosides, such as decyl glucoside and caprylyl glucoside, tend to have low toxicity concerns.' EWG also said the product scored 'low' in terms of health concerns for the environment, cancer, and developmental and reproductive toxicity.
• It smells divine: Coming with a minty-fresh smell, one spritz of this cleaner will leave your windows, mirrors, and space feeling fresh and so clean. The mint aroma will help act as a natural pest repellent for your windows as most pests do not like this scent an will steer clear.

It's worth noting, according to EWG, three ingredients out of the eight were rated a 'C' or 'D'.

This includes the fragrance, polymeric pink and polymeric blue. 'The word ‘fragrance’ or ‘parfum’ on a label is an umbrella term that can mask sometimes dozens of individual chemicals,' explains Samara.

While Samara says 'Polymeric Pink' and 'Polymeric Blue' are non-specific chemical names which only reveal their function as colorants or coloring agents to the public she explains that many companies use the terms 'dyes', 'colorants', or 'colors' instead of listing the specific chemicals.

'Many ‘colorants’, including polymeric pink and polymeric blue are considered trade secrets,' the Samara explains. 'The trade secret status of chemicals masks both structural data on the molecular makeup of an ingredient or mixture as well as the toxicity data from regulators, NGOs, academics and the public.'

While I love the smell of mint and use it religiously around my home, some may prefer to have an unscented glass and mirror cleaner. If that's the case, this Citra Solv Homesolv Natural Window & Glass Cleaner from Amazon, which has received an 'A' rating from EWG, could be better suited.

How to use it

Let's face it: learning how to clean a window or how to clean a mirror without streaks might not be rocket science, but it does take a little know-how to ensure you get a sparkly, streak-free finish.

For example, there are some window cleaning mistakes you'll want to avoid. Like failing to dust first or applying too much pressure.

Luckily, cleaning whizz Sofia has shared her words of cleaning wisdom.

• Mist lightly. Too much product can create streaks or film.
• Use a folded microfiber cloth, like these HOMEXCEL Microfiber Cleaning Cloths from Amazon, which you can pick up for under $7, and rotate to a clean section as you go.
• Wipe in long horizontal or vertical strokes, not circles. It’s easier to spot streaks and get a uniform finish.
• Avoid direct sunlight while cleaning. The heat causes the cleaner to dry too fast and leaves residue.
• For a final polish, go over the surface with a dry, clean cloth.

'I recommend a deep clean every two to three months,' Sofia says. 'If you're near construction zones, high-traffic streets, or heavy pollen, monthly is better. Dirt buildup can dull natural light and shorten the life of the window surface over time.'

Whereas when it comes to freshening up your mirrors, Sofia recommends doing so every week. 'Weekly is a good baseline, though bathroom mirrors may need a wipe-down every few days, depending on humidity and water spots.'

Who is it good for?

Method's glass and window cleaner is best suited to those who are trying to create a less toxic space, yet they still want a product that's going to be effective on smudges and smears.

'From experience, I’ve found the key ingredient that makes it work so well is the inclusion of plant-based surfactants and corn-derived alcohol,' Sofia says. 'The alcohol allows the formula to evaporate quickly, which is essential for a streak-free finish, especially on sunny days or large windows.'

Therefore, this is a great non-toxic cleaning product to shop for if you're wanting to branch out to non-toxic cleaning supplies for your home.

Verdict

Overall, I don't think you can go too far wrong with this cleaning product. It does what it says it will do on the tin – which is help you achieve a sparkly streak-free shine, without costing the earth.

I love the fact that Method's glass cleaner, available at Walmart, it's been 'green-rated' by EWG, meaning it's one of the safest available cleaning options around to have in your home.

But the icing on top of the cake for me is the fact that it doesn't upset my allergy-prone household.

8/10.
