No one expects scrubbing a toilet to be fun. But we don't expect it to be toxic, either. Yet some of the ingredients in conventional household cleansers are scarier than the grimy germs they aim to scrub away.

According to the Environmental Protection Agency, pollution levels can be 10 times higher indoors than outdoors, thanks in part to harmful chemicals lurking in products found under most kitchen sinks. Phthalates, for example, which maintain product fragrance, have been linked to male reproductive problems. Phosphates and foaming agents called NPEs (nonylphenol ethoxylates) are harmful to marine life once they reach waterways. And lots of cleansers contain petroleum-based distillates made from nonrenewable oil.

Because the industry's labels aren't regulated, any company can call its soap or detergent "natural" or "non-toxic." (To check a product's label, check out Consumer Reports' Eco-Labels Center.) So when buying so-called "green" cleansers, it's important to make sure they don't just say it; they spray it. Here's Greenopia's Top 5 best green cleaners.

5. Bleach giant Clorox recently launched Green Works, a line of cruelty-free glass, bathroom and all-purpose cleansers that are 99 percent free of petrochemicals. They work great and are perfect for someone 'transitioning' to toxin-free cleaners from traditional kinds.

4. Vermont-based Seventh Generation has been making socially responsible household products for nearly 20 years (organic cotton tampons, anyone?). Their Free & Clear line promises no dyes or fragrances.

3. Method is the hipster's green cleaner. With a big marketing push by Target, this brand promises non-toxic, biodegradable and phthalate-free soaps and sprays made from things like corn, coconut oil and soda ash. Their stylishly designed bottles are made from 100 percent recycled plastic.

2. Mrs. Myer's Clean Day makes biodegradable, cruelty-free and phosphate-free cleansers in kicky garden scents like geranium, basil and even the occasional rhubarb. The super-fresh aromatherapy-quality products make your place smell clean and delicious.

And the Top, Greenest Cleaner Ever?

1. Make your own from baking soda, vinegar, lemon juice and some elbow grease.

While it's nice to see the cleanser market get a healthy wipe-down, the truth is you don't need fancy soaps and formulas to clean a house. Our grandparents have known for decades you can set your home sparkling with basic — and utterly safe — grocery-store staples. Sprinkle baking soda on your carpet and vacuum it up for fresh-smelling floors, or mix it with water for an oven cleaner. Soak laundry in water mixed with lemon juice or hydrogen peroxide to remove stains. Clean windows, mirrors and floors with vinegar.
