Teach you how to clean the oil on the stone

- Mar 22, 2018-

The stone surface, such as oil pollution, can be cleaned with stone cleaning agent, and there are two solutions to remove the oil pollution on the stone.


Solution 1: remove the oil from the polished surface or the white granite surface of the grindstone surface, and can be operated according to the following steps:


(1) initial cleaning: initial comprehensive cleaning can help identify the contaminated area and use neutral detergent with pH between 7-8.5 to avoid any possible corrosion or color change to granite, cement paste joints and adjacent areas. Use frictionless brushes or cotton pads for cleaning. Note: special attention should be paid to safety for products that have damage to the stone.


(two) chemical cleaning: when the surface is dry, there will be a dark stain on the oil stain. Because the removal of stains is a continuous process of trial and error. We think that chemical agents (decontamination, wax removal or deoiling and degumming agents) should be smeared at the contaminated place first. Use the agent according to the manufacturer's instructions in order to ensure the best effect.


The temperature of the use of the scavenger is between 15 and 27 degrees centigrade. When cleaning, keep the surface moist, let the scavenger fully infiltrate into the stone interior, and react for a few hours to absorb the pollution to the surface. If necessary, repeat it again. If the effect is still unsatisfactory, it is recommended to use Poultice.


(three) scavenging drug paste (Poultice): the cleaning of the paste refers to the absorption of the stain into the paste. In order to improve the effect, different scavengers can be added to the paste. The contaminated area soaked, and then deposited on the paste, covered with a layer of plastic cloth, then some cracks cutting plastic cloth, make medicine paste drying, stains can absorb. The whole process of adsorption and drying varies for 1-24 hours. The use of paste is an effective way.


(four) protection: after the removal of oil pollution, the surface of granite is washed with water and dried. The next process is to protect it so as to avoid the future pollution. The silicone permeable protective agent can protect the stone from oil stains most effectively. The difference between the permeable protective agent and the surface type protector is that the former can completely infiltrate into the stone, and any residual on the surface should be removed. Once the surface is properly protected, pollutants can also touch the surface of stones, but they will not penetrate into the interior of stones. This will make the later stain removal work simple and effective.


If the table is coarse-grained granite or marble, it is recommended to use surface protective agent (protective agent will form a protective coating on the surface of stone) to achieve the best protection after finishing with penetrant protective agent.


(five) maintenance: to ensure the appearance of stone lasts for a long time, can use neutral cleaning daily cleaning agent, if necessary, can be performed by polishing polishing surface, use polishing agent will also protect the stone surface from dirt and water infiltration, and can make the stone show high brightness.


Solution two: the above description is a common problem for granite mesa. Granite is an absorbent material that will inhale the oil in the cooking. Almost no detergent can remove the oil from the interior of the stone. However, a technique called Poultice can adsorb the pollution inside the granite and restore its original color. After the removal of oil pollution, it is recommended to apply high quality anti oil seepage protection agent.


Poultice is a kind of powder like substance that can adsorb pollution. The powder is mixed with a scavenger and can be used to break down stains and be absorbed into the powder. For alkaline detergents available oil and drug mixed aleurone to clear, specific steps are as follows:


(1) clean the surface completely and thoroughly by cleaning the soap and water with the stone, so as to remove the surface oil as far as possible.


(2) scour the table with clean cold water and dry the water with cotton cloth.


(3) the medicine with the usual aleurone detergent mixture mix, until the formation of a thick paste.


(4) apply the paste to the oil area carefully, and the thickness of the paste is about 5 millimeters.


(5) the use of plastic cloth or wax paper cover with a pollution medicine paste, all sealed with tape, adhesive tape is best to use a small.


(6) let the paste react for 24 hours, uncover the plastic cloth to see if the paste is dry. If the paste is dry, keep it dry. The medicine can be completely dry paste, oil absorption.


(7) in addition to the detergent paste, check the stains, if the oil still exists, can be repeated operation once. It may be four to five times to try to remove the oil.


(8) after the removal of oil pollution, we should use silicone protective agent to protect the table. If the above steps are not effective, we can use stronger cleaning agents.
