I make homemade liquid laundry saop and when I use

At home, you are not making your own laundry detergent, you are making soap. Soaps and detergents are not the same thing.

The soap does not rinse out as well as the detergent and it tends to build up on clothes. This is because the soap will combine with the magnesium and calcium ions in hard water and will create an insoluble residue.

Also the soap is is less powerful than the synthetic detergent and tends to lose its cleaning power over time.

Your washer may require HE laundry detergent. Or your detergent is not compatible with the specifications the washer was designed to function under. Using improper detergent can cause operational issues and void warranties.

You NEED to buy real washing soap from a store. I recommend Tide because you may be mixing wrong ingredients or not adding something. If buying new/real soap doesnt work i would go to a sears or email sears at their website and tell them.
