Hello, I'm glad to answer your question. Bulk detergent is widely used in hotels, restaurants and other restaurants. Now with the improvement of technology and equipment, the washing effect of bulk detergent is quite good, and the PH value is neutral between 7 and 8, which does not hurt hands. The most crucial point is that the price of detergent in small barrels in supermarkets is about one third, which is relatively affordable in short. They are usually sold near the vegetable market. I run two farmhouse businesses in Linqu County, Weifang City, Shandong Province, and I have a good demand for detergent. Considering the cost, I used a big bucket of detergent two years ago, which is very cost-effective. The name of Tan detergent delivered to me is Ersong brand, and the quality is not bad. He said he delivered takeout to more than 400 local restaurants.
