People of all ages want to make sure they have healthy safe cleaning products that won't harm their kids, elderly or even their pets.

What if you found out the cleaner you were using had terpenes? Terpenes can form formaldehyde when released against the ozone in the air, according to research by the Environmental Working Group.

"In an effort to help consumers find safer products, the Environmental Working Group has created the first online guide that rates more than 2,000 household cleaners with grades A through F for safety of ingredients and disclosure of contents," according to a statement from the group.

Some brand names received a passing and failing grade because of different variations in their product.

We've listed the top 10 highest- and lowest-ranked items of household cleaners in 10 categories, which include: air fresheners all purpose, bathroom, dishwashing, floor care, furniture, kitchen, laundry cleaner and other cleaners, as provided by the group.
