I have a front load washer that saves energy with the water and electricity. I have found that my clothes are in need of softening up. There seemed to be a soap build up in them. I have a "rinse only" button on my machine.
This page contains the following solutions.
This laundry ball is used in the washer and reduces consumption of laundry soap by 75%. It enhances the cleaning of clothes. It is solar powered so you put it in the sun once a month.
From time-to-time it is a good idea to check and see how much soap is left in your clothes. You might be surprised!
