My mother and my grandmothers and other relatives always added the half measure of detergent to subsequent loads whether in the wringer or suds saver washers. I still remember the delightful fragrance of Blue Cheer in my aunt's wash water that could last for a two or three hour wash day which was a race against time and falling water temperatures, another reason for boosting the detergent charge in the wash water.
I also remember my mother putting newspapers on the basement floor and sorting loads to be washed when we had the suds saver washer because it took discipline to move those loads through the process, especially in the summer when we would pull in from a trip on Friday, wash everything on Saturday, when it could be so hot that one load hung out was almost dry by the time the next one was ready for the lines. Daddy's dress shirts were taken to the cleaners and last week's shirts were picked up to be packed for our next trip. After the suds saver was gone, sometimes we would get a head start by washing a load on Friday night to hang it out extra early on Saturday and everything had to be done on Saturday because only the drug stores were open on Sundays and lawns were not mowed on Sundays, although the quieter forms of yard work could be done then.
Does anyone remember those boys' pants called sand pipers or clam diggers that came about 3/4 of the way down the leg and had a contrasting stripe on the outside of the leg? Ours were white with a black stripe that split into an upside down Y at the bottom of the leg and were 100% cotton. Those were washed and ironed before the next trip. My brother and I lived in swim suits and shorts during the day and changed into those before going to dinner. As soon as we got back to the motel room or apartment, we took them off and put them on hangers for the next wearing. We were very careful with our use of cloth napkins to keep them clean.
