When clothing is repeatedly exposed or soiled, more pesticide remains in the clothing after washing, and there are higher concentrations of chemicals in the rinse water. Pre-rinse clothing before washing. This helps remove a large amount of pesticide. Pre-rinsing can be done by hosing clothing off outdoors, soaking them in a tub or bucket, or using the presoak cycle in the washer. Wash pesticide soiled clothing in hot water of 140 degrees or higher.
Hot water removes more pesticide.
Use a heavy-duty liquid laundry detergent. They are better at removing pesticides and are especially helpful in removing oil-based pesticides. Use the amount of detergent recommended on the product label. Neither bleach nor ammonia seem to affect pesticide removal. Use the full water level on the machine, and wash only a few clothes at a time so water can circulate freely.
