Never Use Bleach on These Surfaces

Bleach has a ton of uses outside of lifting stains from white clothes, but there are some dos and don’ts we should all remember. You already know to never mix bleach with any other cleaners or disinfectants, as it can release dangerous vapors, but there’s more that you should avoid.

What you can use bleach on

According to Architectural Digest, bleach can kill bacteria and pathogens left on surfaces after an initial cleaning. It’s not a cleaner itself, but works within 10 to 60 minutes of contact to kill what’s left behind after your first run-through with soap and water or another cleaning agent.

What you shouldn’t use bleach on

That said, there are some surfaces you should not bleach down:

• Laminate
• Stone
• Marble
• Granite
• Quartz
• Aluminium
• Silver
• Copper
• Enamel (with chips in it)
• Anything electronic

The reasons for avoiding bleach vary: For instance, bleach can eat away at the protective coating on laminate and damage the laminate paper beneath, or bleach can eat away the sealants on stone countertops, discoloring them. Basically, it’s too corrosive to be trusted on certain surfaces, but it’s fine on glazed ceramics, plastic cutting boards, painted wood, and the like. Since you need to leave bleach on surfaces for a while to really disinfect them, you can guess how this erosion might be a problem.

You also shouldn’t try to clean grout with bleach, although you may read recommendations elsewhere that you should. Since grout so porous, bleach can really fade and erode it.

Dilute your bleach, but never with hot water

You may have heard that bleach should be diluted, but you may not know how much. According to the Centres for Disease Control and Prevention, you should first follow the instructions on the bottle you have, but if it doesn’t have instructions, use ⅓ cup of bleach per gallon of room-temperature water or four teaspoons per quart of room-temp water. Never dilute bleach with hot water, as this can allow some bleach to waft into the air with the steam, irritating your eyes and nose. Plus, hot water breaks down the bleach’s chemicals more quickly.

Even when diluting it just right, you should use bleach in rooms with good ventilation to avoid breathing the stuff in. Open your windows and doors. Wear gloves and protective materials, too, as well as old clothes you wouldn’t mind getting a bleach stain. (You can always turn them into cool tie-dye after a mishap, though.)
