2x detergent is a concentrated detergent that is twice as strong as regular detergent. It is not specifically formulated for use in high-efficiency (HE) washing machines. HE detergents are specially designed for use in HE washing machines and are low-sudsing, which is important for the proper functioning of HE washing machines.
Using regular detergent (like 2x detergent) in an HE washing machine can cause the machine to malfunction and create excessive suds. This can lead to problems such as poor rinsing, detergent residue on clothes, and damage to the washing machine itself. Always check the detergent label to ensure that it is specifically formulated for use in HE washing machines before using it.
