Let your dye-smelling clothing soak overnight in a bucket filled with water and 1/2 cup of baking soda and 5 drops of lavender essential oil.
Wash your dye-smelling clothes alone and using a hot water cycle, unless otherwise specified on the clothing's care instructions. Do not use fabric softener, which can amplify the bad dye smell from your clothes. Set your washing machine for a delayed final rinse cycle.
Add 1/2 cup of white vinegar to the wash right before the final rinse cycle.
Hang your clothing to dry outside and in the sun, if possible, or dry them in a dryer.
Leave your washer open to air out after washing your dye-smelling clothes.
