Homemade Disinfectant Spray: Rosemary & Mint

As part of our “Make It at Home Day,” my friend Rachael and I whipped up a batch of this refreshing and powerful homemade disinfectant spray—and now I’m hooked. With just a few ingredients, you can clean surfaces naturally and avoid the toxic load of many store-bought cleaners.

Why Go Homemade?

Many regular disinfectants have strong chemicals that can be harmful to people and the environment. Common ones include:

Ammonia – This is found in many glass and surface cleaners. It can irritate the eyes, skin, and lungs. Breathing in too much can make asthma worse and cause coughing or burning in the throat.

Bleach (sodium hypochlorite) – Bleach is a strong disinfectant, but also very harsh. It can burn the skin and eyes. Mixing bleach with other cleaners can create toxic gas. Even on its own, bleach gives off strong fumes that hurt the lungs.

Quaternary ammonium compounds (“quats”) – Quats are often in wipes and sprays. They can cause asthma, skin rashes, and may affect fertility. These chemicals can stay on surfaces and pollute indoor air.

Synthetic fragrances – Many cleaners use fake scents to smell pleasant. These scents often contain hidden chemicals. Some can cause headaches, allergies, or breathing problems. Others may affect hormones in the body.

Formaldehyde – Used to preserve some cleaners, formaldehyde is a known cancer-causing chemical. It can irritate the skin, eyes, and lungs. Long-term exposure can lead to serious health problems.

Safer, Natural Options

While these ingredients can kill germs, they may harm your health. Safer, natural options are a better choice for many people.

Even some brands marketed as “natural” have changed their formulas after being bought out by big corporations. A great example is Mrs. Meyers, which started off with cleaner ingredients but now contains synthetic fragrance and other questionable additives. It’s hard to know who to trust anymore, which is exactly why we’ve turned to DIY for this homemade disinfectant spray!
