First, I should say I realize they’ll never really be free of the smell of coolant. Been doing this too long to dream of that. But it’s there a trick to minimizing the smell after laundering? I was them separate from my regular clothes but would still be nice to put on cleaned clothes for work and not smell like ice already worked a shift. Thanks
Air dry outside when possible. I washed work clothes for many years with this odor. There is no sure cure. Use a detergent like Oxiclean.
You might try a cup of vinegar and 1/2 cup of baking soda (no detergent) tossed in when the washer has filled with hot water. Worked to the mildew odor out of some towels and clothes.
