Is Ammonia in Glass Cleaners Bad for Your Health?

Cleaning windows without ammonia

Ammonia is one of the most common ingredients in household cleaners. It's also one of the most potent respiratory irritants in the home; and it's in more products than most people realize.

When people think about dangerous cleaning chemicals, bleach usually comes to mind first. Ammonia tends to fly under the radar.  It doesn't carry the same reputation, and its presence in everyday products like glass cleaners, floor polishes, and multi-surface sprays rarely raises concern. But the research on ammonia's effects on the respiratory system tells a different story, especially for people with asthma or heightened chemical sensitivity.

Where ammonia shows up

Ammonium hydroxide, the form of ammonia used in cleaning products is a high-pH alkaline compound that cuts through grease and grime effectively. That's why it's so widely used. But it also means the products that contain it are among the strongest airway irritants in a typical home. You'll find it in:

• Glass and window cleaners,  including the most widely recognized brands on the market

• Multi-surface and all-purpose sprays,  often labeled simply as "heavy duty" or "degreasing"

• Floor stripping and polishing products,  common in both household and commercial cleaning

• Some oven cleaners and bathroom disinfectants particularly those marketed for tough buildup

The American Lung Association specifically flags ammonia as a chemical that contributes to chronic respiratory problems and allergic reactions with regular use.

What it does to the airways

When inhaled, ammonia is almost completely absorbed by the upper respiratory tract, meaning the nose, throat, and airways bear the full force of irritation every time it's used. Over time, that repeated exposure causes inflammation, increased airway reactivity, and for people with asthma, measurably worse lung function on days ammonia-based products are used.

Asthmatic airways are more sensitive to ammonia, not less

Research from the Monell Chemical Senses Center found that people with asthma show lower irritation thresholds to ammonia than healthy individuals, since they detect and react to ammonia at lower concentrations. For someone with asthma, it can be enough to set off an attack; even at the low concentrations present during routine household cleaning.

The sensitivity pattern

People with chemical sensitivities often can't identify which specific product is triggering their symptoms. Because ammonia is so common across product categories and because its fumes linger in enclosed spaces like bathrooms and kitchens, it's one of the most frequent but least recognized culprits behind cleaning-related respiratory flares.

Critical safety reminder

Mixing any ammonia-based cleaner with bleach produces chloramine gas: a highly toxic compound that can cause severe respiratory damage and has been fatal. The American Lung Association states this combination can lead to chronic breathing problems and death. If you're unsure whether a product contains ammonia, check the ingredient list for "ammonium hydroxide" or "ammonium chloride."

What we do differently at Lumina

Ammonia-free formulas aren't a compromise,  they clean just as effectively without the respiratory cost. At Lumina, we don't use ammonium-based products in any of our cleaning work. It's a straightforward call when the alternative is bringing a known airway irritant into a home where someone may have asthma, sensitivities, or simply no idea what's being sprayed around them.
