Can you clean hardwood floors with bleach?

Here’s the expert’s take: can you clean hardwood floors with bleach? The answer is no. 

Professional cleaner, Shandel Small, says you should never use bleach on hardwood floors, especially at full strength or it will strip the wood, damaging it and lifting the color. As wood is a natural material with a porous surface, the bleach is too caustic to use, even on treated wood.

What the expert says...

Shandel Small, Professional cleaner, says, “You cannot use harsh chemical detergents on hardwood floors, especially bleach. You will damage your floors. Use a gentle, specialist wood cleaning product such as Zep.”

Most hardwood floors are treated with a protective finish by applying stain, wax or lacquer as a protective coating. As bleach is highly caustic, meaning it will strip the finish away, breaking it down and getting to the wood underneath.

Have you ever accidentally spilled bleach on your favorite sweatpants? If so, you’ll know that it lightens all materials it comes in contact with especially porous, organic ones like wood. Using bleach to clean hardwood floors with, especially in high concentrations, could lead to patchiness and discolouration. 

What can you use to clean hardwood floors instead of bleach? 

So, can you clean hardwood floors with bleach? Simply put, no. The active ingredient, sodium hypochlorite, is highly corrosive and wood is too vulnerable to corrosion due to being a natural material. At the very least, using bleach will corrode your finish, if not the wood beneath. 

You might be wondering what you can use to clean hardwood that won’t erode the surface. Gentler cleaning products designed for wood exist and are available widely at stores. Cleaning expert Shandel uses Zep wood cleaner but many other similar wood-specific cleaning products are available.
