i have mixed colors with whites when pressed for time and it doesn’t really make much of a difference the first few times. If you do it too often the whites will get dull.
I am very excited about my new washing machine that i bought outside of the budget abba_s laid out for me. it is HUGE compared to my old one and even though i am still folding 4-5 loads worth of laundry, i only have to wash about 3. really cool!
