When cleaning thick greasy dirt on food street pavement, kitchen greasy dirt or road greasy dirt on ordinary roads, the method of use is: pour the prepared cleaning agent into a watering can, when the cleaning area is small, use a watering can for watering flowers; When it is large, it is best to use a sprayer for spraying pesticides. Shake the watering can or sprayer well before using the cleaner. When using, spray the cleaning agent directly on the ground with oily stains. It is required to completely cover the oily stains on the road surface, soak for 5-10 minutes, and then wash with water. If the thick oily dirt on the road surface is thick, it can be repeatedly sprayed on the road surface to clean it several times until it is cleaned. For stubborn stains, it is recommended to use a harder brush (such as the brush used to clean the toilet at home) to scrub several times after soaking, and then rinse with water.

Suggested dosage of oil stain cleaner: use 100 g of the prepared detergent to clean every 4~6 m ² of stains.

When the prepared cleaning agent is used to remove lampblack and kitchen grease, it can be diluted with water by 1 to 5 times, and the specific concentration depends on the cleaning area and the firmness of the greasy dirt. Spray and moisten the grease dirt with cleaning agent for 10-15 minutes, then wipe it off with a hard brush, then rinse it with clean water, and reuse it if necessary.

It must be emphasized that the above examples are only examples for clearly illustrating the present invention, rather than complete limitations on the implementation and composition of the cleaning agent formulation. Those of ordinary skill in the art can also make other changes in different forms on the basis of the above description.
