Clean the courtyard with white stones

 


Cleaning method and precautions for blackened white stones:

When cleaning the stone, it is best to soak it in clean water for a period of time. The specific soaking time depends on the contamination of the stone. Then, repeatedly scrubbing, as long as it is not contaminated by oil and rust, this method will generally clean the stone. Clean water, suitable for any stone, will not harm the stone.

The second is to add an appropriate amount of detergent in the clean water: if the stone is contaminated by oil and the water is difficult to clean, at this time, you can add an appropriate amount of detergent in the water, then stir evenly, and soak the stone in it for a while After time, after the oil on the stone is decomposed and melted, slowly scrub with a brush until the oil is cleaned.

Then soak the stone with clean water to remove the oil and detergent remaining on the stone. Finally, rinse it with clean water repeatedly until the oil and detergent are thoroughly washed away.


The third is to add proper amount of oxalic acid in the clean water: For stones with serious dirt and rust (note: the picture stones are not suitable for cleaning with oxalic acid), if the first two methods can not be cleaned off, you can add proper amount to the clean water Soak oxalic acid for a period of time, and then repeatedly scrub with a brush.


(Caution: Oxalic acid is corrosive. Do not directly touch the oxalic acid solution when cleaning, and you must take precautions in advance). After cleaning, wash the stones repeatedly with clean water. Finally, put the stones in clean water for soaking and washing until the oxalic acid is thoroughly cleaned.


Special reminder: The strange stones of limestone are not suitable for cleaning with oxalic acid, because oxalic acid is easy to chemically react with the stone to destroy the stone! In addition, all kinds of picture stones are not suitable for cleaning with oxalic acid, because the picture of the stones can easily be destroyed during the cleaning process.


Selection of tools for cleaning stones:

The toothbrush is the first choice, which will not damage the stone skin. The fine pores on the surface of the stone and the dirt in the crevices can be thoroughly scrubbed.

The second is shoe brush, which is suitable for stones with rough structure and stubborn dirt.

The second is a steel wire brush, which is suitable for stones with rough structure and high hardness, and it is difficult to remove dirt with a brush.


Special reminder : For soft stone, it is easy to damage the stone with a wire brush. It is recommended to use with caution.

  Bedroom storage The bottom of the bed must have a higher clearance from the ground, generally 10~15cm is better , so that the dust underneath can be removed. Now there is a sweeping robot . The ground clearance must at least allow "it" to enter and exit freely; or the bed is located on the floor There are no gaps on the top, so you only need to clean around the bed. The biggest item in the bedroom is the seasonal bedding-piles of quilt pillows, which are generally stored in the "low-quality space" at the top of the bedroom closet. If the area of the room is large enough, the cabinet can be appropriately deepened, so that the bedding can be placed more loosely to avoid being squeezed by the stack to the cabinet door.
