Benefits of green cleaners

Benefits of switching to green cleaners can include:

  • Improved worker safety and health, and fewer sick days [1,2].
  • Reduced disposal costs. Many places charge to dispose hazardous waste [1].
  • Improved ability to meet environmental goals [2].

Switching to green cleaners in your workplace improves indoor air quality by reducing the amount of toxins, carcinogens, allergens and harsh odors in the air. [6]

It can also have a big positive impact on the health of janitorial staff in your building. Over 2.8 million people are employed as janitors in the U.S. Data from Washington State show that about 6 percent of janitors experience a job-related injury from chemical exposure to cleaning products every year [1]. 

Conventional vs. green cleaners

Conventional cleaning productsMany contain harmful chemicals that are toxic to both people and the environment. In general, these products aren’t any better at cleaning than non-toxic cleaners that are safe to use and have a low environmental impact [5].

Green cleaning productsAre absent of harsh chemicals that make people sick and can create air and water pollution [1].

What makes a cleaning product green?

  • Certified by Green Seal, UL ECOLOGO or UL GREENGUARD - Independent, third-party certification ensures green products live up to their claims. Learn more about ecolabels below.
  • Concentrated with clear dilution instructions – Ready-to-use cleaners are 90 percent water. Buying concentrated cleaners prevents packaging waste. However, proper dilution is key to a product’s safety. Learn more.
  • Packaged in recycled and recyclable materials – Reduce waste by choosing products that use smart packaging.
  • Neutral in pH – Acidic and alkaline products can burn skin. Look for products with a neutral pH of 7.
  • Non-toxic – Avoid products that have a danger, warning or caution label.
  • Free of chlorine bleach – Chlorine bleach and the wastewater from using chlorine bleach can react with other chemicals. Look for products that have a Processed Chlorine Free or Totally Chlorine Free label.
  • Made from renewable resources – Petroleum-derived products are flammable and made from a non-renewable resource. Choose renewable alternatives, like citrus, seed, vegetable and pine oils. 
  • Works in cold water – Cold water uses less energy than hot.
  • Low VOC - Low volatile organic compound (VOC) content.

Products to avoid [3]

Antibacterial products

  • The FDA states, “There currently is no evidence that over-the-counter antibacterial soap products are any more effective at preventing illness than washing with plain soap and water” [4].
  • Additionally, the chemicals used in these products “may alter the way hormones work in the body,” and may make, “bacteria resistant to antibiotics [which] can have a significant impact on the effectiveness of medical treatments” [4].
  • Alternative: soap and water, green cleaners.

Air Fresheners – contain fragrances that can trigger allergies and asthma.

  • Alternative: Open a window or use fans.

Drain cleaners – are caustic and can burn eyes and skin.

  • Alternative: Use a plunger or drain snake, or baking soda and vinegar.

Ecolabels for Green Cleaners

When buying green cleaning products, not all labels and certifications are equal. It is important to buy products with independent third-party certifications that are backed by widely-respected and trusted organizations. If you don’t have time to research ecolabels, we recommend Green Seal, UL ECOLOGO and UL GREENGUARD
