How to treat cement stains with specialized detergent:

Units in charge of post-construction cleaning will often carry out the following cleaning steps:

2.How to treat stains from paint

Not only cement stains, but paint stains on the surface are also commonly seen during construction. During post-construction cleaning, these paint stains are usually quite stubborn, so a separate method is needed to clean them. Clean House introduces a few cleaning methods as follows:

Treat paint stains with vinegar:

• Dissolve a mixture of vinegar and warm water. Pour the solution into a handheld sprayer. Absolutely do not pour vinegar directly onto the floor surface, especially wooden floors, because it can cause the floor to erode.
• Using a spray bottle, spray on the paint patches and use a cloth to wipe over and over until the stains are removed. Finally, wipe with clean water to remove the smell of vinegar.

Treat stains from paint with specialized chemicals:

• Step 1: Pour a sufficient amount of specialized chemicals onto the surface of the paint stain, then leave for about 1 minute for the chemicals to act on the stain.
• Step 2: Use the mesh to scrub the paint stains clean. Note that for tile floors with many protrusions or crevices, using a whisk will be more effective. On the contrary, if the surface is flat, it is better to use a carving knife.
• Step 3: Use a cleaning cloth or broom to clean the floor. Repeat until all paint stains are removed.
