The hotel kitchen drain is full of oil, how to solve it?

Go to a chemical store, buy a few kilograms of flake alkali (sodium hydroxide), divide it into several portions, melt it with water, and rinse it every few days.

1.Rinse the ground with 4-5% hydrochloric acid, the method is similar to priming, scrape with a knife, the oil is particularly heavy and can be pushed several times in this process, a large number of bubbles will appear on the ground, for the normal phenomenon, hydrochloric acid will corrode the cement containing oil, and according to the number of bubbles, you can apply it again (more bubbles), but not more than twice, the preparation method of hydrochloric acid, commercially available concentrated hydrochloric acid (37% content) a scoop of water about two kilograms, poured into the bucket of about 15 kilograms of water, in this process, must pay attention to safety, ventilation, hydrochloric acid splashed on the body should be immediately rinsed with a large amount of water, not wiped with a cloth.

2.Wash the ground with alkali, about 1 kg of commercial caustic soda (chemical name sodium hydroxide), 20 kg of water, scrape the ground once, neutralize the hydrochloric acid on the ground, and the amount of alkali washing in this process can be slightly greater than pickling.

Rinse with laundry detergent or slippery liquid.

Boil a large bucket of boiling water and pour it down 3 times a month to solve it completely.
