The best window cleaners are among the most expensive and the ones that have the most promise are the ones designed to remove grout from windows, as well as clear up debris.
However, most of them also contain toxic ingredients that may increase the risk of health problems, including the chemical bisphenol A (BPA).
The best window cleaning products are made from materials that contain a wide variety of ingredients, including synthetic rubber, glass, wood and metal, said Richard Bick, a senior research associate at the American Chemical Society.
Most of the chemicals are water-soluble and thus require a rinse.
“The more you use, the more you need to rinse,” Bick said.
Many window cleaning brands claim to be free of BPA, but the EPA has not approved any BPA-free products.
The agency requires companies to test products for the chemical, but has not yet mandated a testing program.
Some people, however, have begun to try to remove the chemical.
“I’ve been using some BPA free window cleaners for years,” said Stephanie S. Wolders, an associate professor of environmental health sciences at the University of California, Berkeley.
“When I use them, they’re very effective and I’ve been able to remove all of the BPA from them.”
Another way to remove BPA is to soak the window in a water-based solution.
However that is a less effective way to get rid of the chemical because it does not dissolve and the window remains soft and porous, WoldERS said.
The best option is to spray on the window before you use it, she said.
“You’ll see the Bisphenols dissolve.
So if you can spray on it with a water sprayer, then you’ll be able to get a better spray.”
Another option is using a glass cleaner, which is an adhesive that can be applied to the surface of the glass.
This method also does not require a wash.
However the adhesive is less flexible and does not remove the BPS.
If you have an old window that you’re concerned about, try a window cleaner made from a different material such as recycled glass or copper.
This will remove the bispheres more easily and it will not cause damage to the glass, according to a study published in the Journal of Environmental Science and Health.
