This shortcut was discovered by accident. I ran out of dishwasher detergent so substituted laundry soap instead. I cut back the amount by half. The kitchen flooded with water and soap suds. So I threw a basket of laundry over the kitchen floor to mop it all up and tossed the wet clothes in washing machine without adding any more soap.
1) clean dishes
2) clean kitchen floor
3) clean load of laundry
All at once and with half the usual amount of soap. And this taught me to use less laundry detergent ordinarily. A lot less, that stuff is quite strong with a lot of cleaning power and some stays in your clothes causing itching. You can tell because if your hand is wet and you grab a handful it burns.
