How to Clean Basement Air

Basement air can be extremely dusty and full of mold spores.

Not only does this cause your basement to smell bad but it also makes the air quality worse for your health.

To clean up your basement air, all you need is an air purifier.

Air purifiers work by using fans to circulate the air through a series of filters, which then trap debris and floating particles, like dust, allergens, and mold.

By running an air purifier in your basement, you can have a finished or unfinished space that smells fresh and stays clean.

Check out our guide on the best basement air purifier that shows you how to pick the right one for your needs.

How to Clean Basement Floor

The next step for how to clean a basement is learning how to clean basement floor.

To begin, remove every item you can from the room.

Or, work in sections by moving everything to one side (or corner) of the room and cleaning that area first.

Once the floor has been cleared, use either a broom or vacuum to clean up any settled dust and dirt.

If you’re cleaning an unfished basement, use a broom first, then follow up with a vacuum to get as many particles up off the floor as possible.

If you’re cleaning a finished basement with a rug, just use the vacuum cleaner.

After you’ve swept and vacuumed up all of the dirt and debris, you can then do a hand scrubbing and wet mopping of the concrete floor to get rid of any stains.

Take a bucket and fill it with water.

Then add bleach at a ratio of 1 cup to every 5 gallons of water or 1/2 cup to every 2-1/2 gallons of water.

Next, put on a pair of rubber gloves and dip a scouring pad into the bleach solution and scrub away at the floor to remove any common stains.

If there be rust stains on the floor, the bleach solution may not work.

So, squeeze lemon juice or drizzle vinegar onto the stains to loosen the rust stains from the floor.

Wait about five minutes and then use a bristle brush to scrub the area.

If the lemon juice or vinegar doesn’t get rid of the rust stains, you may need to use a commercial rust remover that contains oxalic acid.

Before mopping the floor, rinse away any bleach, lemon juice, or vinegar away with clean water.

Once that has been done, fill a bucket with water and a commercial cleaning solution.

Make sure to ventilate the area well and mop the entire floor.

Once you’ve finished mopping, rinse the floor with clean water.

How to Clean Basement Wall

When it comes to learning how to clean basement wall areas, you have to asses the type of wall you have before starting the process.

Some walls are constructed of cinder blocks while others have smooth concrete or even drywall covering.

With cinder block and concrete walls, you can start by vacuuming them with a hand attachment or use a broom to remove dirt and debris.

Then, you can follow our steps in the previous section on how to clean basement floor to remove any stains on the walls by using bleach, lemon juice, vinegar, or a commercial product.

Once you’re done cleaning the cinder block or concrete walls, make sure to rinse them with water.

For drywall, it’s best to use a commercial cleaner called Trisodium phosphate with a rag.

This chemical does a great job of removing dirt, debris, and other gunk that sticks to drywall surfaces.

How to Clean Basement Ceiling

Like walls, you need to assess the type of ceiling in your basement in order to know how to clean basement ceiling the right way.

If it’s concrete, then use a broom to sweep it clean or a vacuum hand attachment.

Afterward, follow the same advice in the previous section for how to clean basement wall by cleaning the ceiling with bleach, lemon juice, vinegar, or a commercial product.

Finally, rinse the ceiling with water by using a damp cloth.

If the ceiling is made of exposed wood beams, then use a broom or bristle brush to get rid of collected dust and debris.

Then, use soap and water with a sponge to wipe down the wood. If you see any white splotches on the wood, it may be a type of mold.

If that’s the case, fill a bucket with Hydrogen Peroxide and scrub the area with a rag.

The Hydrogen Peroxide should get down and kill the roots of the mold. Always use a respirator and rubber gloves when working around mold.
