How to clean walls after the floor sanding

Cleaning walls after floor sanding is all about increasing the beauty of the painting. The durability of the painting is also a big factor here. In this section, you’ll get a complete overview of how to clean walls after floor sanding.

Wiping walls using wet and dry cloths

First step: Observe the wall

  • Your first and foremost duty is to determine the amount of dust present in the wall. All you need to do is hold a damp cloth up to your wall. Then, perform a gentle swipe using it. If you find a dusty environment on the wall, it needs your help. 
  • In case you find the wall okay, don’t bother washing it. Proceed to the preparatory stage directly. 

Second step: Start wiping

  • Equip yourself with protective instruments like hand gloves, safety cloth, eyeglass, and mask.
  • Next, you need to replace the furniture and other obstacles from the working area. Take a damp cloth to wipe it gently across the surface of the desired wall. 
  • It’s prohibited to perform hard scrubbing on the wall. Rather than washing the wall, it could damage the wall surface. When the debris is extremely layered, make sure to wash them one by one layer. Otherwise, all of your efforts will be for nothing. 

Third step: Rinse properly and perform a dry wipe

  • Submerge a new piece of soft cloth in some clean water. Then, wipe the wall again using the cloth. This step will remove residue dust effectively. 
  • Next, you should wipe the wall using a dry cloth. Though moisture will disappear after a certain time, it’s better to remove it earlier. This process is significant in ensuring the permanence of the paint as well as increasing aestheticism. 

Washing walls using a vacuum cleaner

Step one: Setting up the vacuum cleaner

  • Vacuuming walls is the best way to wash them thoroughly. The suction power of your vacuum will grab all dust easily. However, start by connecting the vacuum cleaner with the power outlet.
  • Attach the vacuum cleaner’s garbage cleaner before turning on the vacuum. Make sure that you use the right operating pressure for washing walls. If you use extremely high suction power, then the sanding may get damaged. 

Step two: Perform vacuuming

  • Place the suction pipe towards the dirty surface of the wall. Activate the vacuum and let it grab all the debris. 
  • Move the vacuum cleaner to catch more and more debris. Stay concentrated because there is a chance of missing any area to vacuum. Repeatedly go through the whole wall to wipe out debris. 

Step three: Applying the extension hose

  • It’s natural that you can’t access all the critical areas of the wall using the regular vacuum hose. Therefore, you should use the extension hose. Attach it with the main hose properly first. 
  • Now, fit the hose to the obtuse corner of the wall. Activate the vacuum cleaner and run it for a while. You need to repeat the process throughout all critical corners of the wall. 

Step four: Final wash

  • The last thing to do is to apply a damp cloth to the whole wall. Run it from one corner of the wall to another corner. It’ll remove all stuck debris and make the wall shinier than before. 
  • In case you’re concerned about the wet wall, you can perform a dry clean. Take a dry, clean cloth and wash the wall- that’s all. 

Going for sponge cleaning

Step one: Prepare the solution

  • Get a hand sponge with a telescope attachment. Never choose an old, dirty sponge unless you want to damage the wall. 
  • Fill up a small amount of regular dish soap in a two-gallon bucket full of water. Don’t use more than one spoon of regular dish soap unless you want to make the wall slippery. 

Step two: Start cleaning

  • Next, start from the top of the wall. Move from the left to right side and keep wiping the wall using the sponge. The sponge absorbs water solution rapidly and so, you’ll need to rinse the sponge several times.
  • Repeat the aforementioned process for every session. When you’re done, a large part of the wall will remain wet. Ensure to dry the wall using a dry cloth. 

Applying all-purpose cleaner

Step one: Prepare and apply an all-purpose cleaner

  • All-purpose cleaner is the best option when the wall contains spots or fingerprints. First, prepare the diluted solution by mixing 1 ounce of all-Purpose cleaner with 4 cups of clean water. 
  • Then, take a dry cloth and submerge it in the solution. Wipe the wall with the wet cloth precisely. All spots will be removed within a few minutes. 

Step two: Produce and apply the cleaner (alternative)

  • If you can’t manage the all-purpose cleaner, then prepare it at home. Mix one unit of distilled white vinegar with two units of water. For better output, put a squeeze of lemon juice into the solution. Mix the solution properly using a stirrer. 
  • The residual process is pretty straightforward. Use a piece of dry cloth to wet it with the cleaning solution. Apply the cloth to the wall and it’ll work just like the all-purpose cleaner. 


Cleaning the wall after floor cleaning is mandatory to maintain the hygiene and cleanliness in the room. You, your family, and your pets can suffer from this dust on the wall in case you do not clean it. Knowing the right way of cleaning is mandatory for that.

The process will not take much time at all. Different methods are available and you can follow any of these based on your convenience. Make sure you do not damage the wall at any cost. Be careful and clean the wall like a pro.
