Teach me how to do LAUNDRY…

Kathleen

Please help!! I’m a grown woman with 2 kids and I obviously don’t know how to do laundry. I can’t figure out how or why all our whites/brights look faded/dingy after washing, they can be new and worn once like both shirts below and after washing they turns out like this. Please give me tips on how to keep my whites/bright clothes clean. I’m afraid of ruining more of my babies clothes.
