Hotel tablecloths are mainly light-colored or pure white cotton cloth, because cotton cloth is absorbent and soft, and light-colored and white can set off an elegant environment and give customers a clean, hygienic, warm and comfortable feeling. Most stains on hotel tablecloths come from food, drinks, vegetable juices and condiments. The specific subdivision may include cream, fish, gravy, vegetable juice, soft juice, tea, coffee, red wine, white wine, soy sauce, vinegar, other condiments and seasoning oil, and even vomit. Because the sources of stains are complex, the distribution of stains is criss-crossing, and the stains exist for a long time, it is difficult to remove stains and clean hotel tablecloths. Nevertheless, as long as we rationally analyze the sources of all stains, it is not difficult to find a washing method. The stains on the tablecloth may be composed of tannic acid, protein, animal and vegetable oils, wine, vinegar, salt, sugar and pigment. Therefore, the following washing scheme can be formulated:

First of all, clean vinegar, wine, sugar, salt and other water-soluble stains;

Secondly, dissolving tannic acid stains with organic acids;

Thirdly, using alkaline solution to remove grease and protein stains; Finally, the pigment stains are removed by oxidizing bleach. According to this treatment scheme, the hotel tablecloth can be washed with water to achieve the ideal effect.

Put a piece of white cotton cloth under the table and soak the tablecloth for three minutes. Take it out and rotate it for one minute to wash away the stains of sugar, wine, vinegar and salt in the water.

Step 2: Add HTQ to the stained stain and wet it for three minutes. After fully rubbing, rinse the stains with clear water to wash away the tannic acid stains soluble in HTQ.

Step 3: Take 5L, wash it with 5ml of HTQ heavy-duty caustic soda, put it into the tablecloth after the caustic soda is completely dissolved, and boil it for 5-take it out and wash it after the oil stains and egg stains on the tablecloth completely disappear. This step is mainly about the oil stains on the cloth and the protein stains on the tablecloth. Because the stains on the hotel tablecloth are old and removed after oxidation in protein, it is the most effective way to remove them.

Step 4: Take 5l HTP bleach, 50g, stir it evenly, soak the tablecloth for 5 minutes at room temperature, throw it away and dry it after all the color stains are eliminated. This step is to eliminate pigment and sterilize. After the above four steps, the tablecloth is bright and white, and the detergent smells pleasant. Try it when you take a shower.
