1、 The laundry detergent should be completely dissolved. If the water temperature is too low, the Washing machine will have difficulty dissolving the laundry detergent. You can first use a small amount of warm water at around 30 ℃ to dissolve it completely. If the clothes are dirty, they can be washed with warm water at 40 ℃ -50 ℃.
2、 Determine which laundry detergent to use based on the material of the clothing. It is better to use synthetic detergent, such as low foam or foam free detergent. Synthetic laundry detergent can be roughly divided into three types: neutral, weakly alkaline, and strongly alkaline. When washing silk and wool fabrics, it is advisable to use neutral or weakly alkaline materials; When washing cotton and linen fabrics with a lot of oil stains, strong alkalinity is the best; When washing clothes with bloodstains, oil stains, and other stains, enzymatic laundry detergent can be used; When washing fabrics with rust, it is advisable to use laundry detergent containing sodium borate.
3、 The amount of laundry detergent should be appropriate. Excessive use of laundry detergent is both wasteful and difficult to rinse thoroughly; If the dosage is too small, the washing effect will be weakened.
4、 It is best to soak clothes for a while before turning on the machine. For particularly dirty areas, they should be rubbed with soap first, and then machine washed.
