Remove Chemicals/Formaldehyde From New Clothing (How-To)

Published: May 21, 2023 | Corinne Segura, Building Biologist

If you’re extremely sensitive and struggling with the chemical residues (including light fragrance cross-contamination, sizing chemicals, formaldehyde, chemicals from the dyes, etc) that come on new clothing here are three protocols designed by the most extremely chemically sensitive.

Those who are not very sensitive can use these protocols by adjusting them (as I will note).

From Linda Sepp’s blog

This protocol has been used on cotton, cotton/bamboo blends, cotton/polyester blends, and a few totally synthetic fabrics. It is not safe to use on silk.

Each step is a 24-hour soak of new clothes, towels, or linens in a series of agents below (rinse several times after each soaking):

  1. Sea salt (or table salt) in filtered water, about 1/4 cup salt to many cups of filtered water, as many as it takes to dissolve all the salt. (Note: Salt can discolor clothing)
  2. TSP (tri-sodium phosphate). 1/4 cup TSP into very hot water, then add sufficient cold water to bring the mixture to the required temperature for soaking the fabric. This can strip colors from clothes.
  3. Milk – 1/4 cup skim milk powder into a plastic bin full of cold water. You can use 1/2 cup of milk for this step, but that can reshape clothes. Less than 24 hours for this step.
  4. White vinegar – 1/2 cup in a bin of cold water.
  5. Borax and washing soda, or borax and baking soda, plus a bit of powdered oxygen bleach. Mix 1/4 cup borax with hot water to dissolve, then add 1/4 cup washing soda or 1/4 cup baking soda plus 1-2 teaspoons powdered oxygen bleach, and enough water to dissolve all of these ingredients.
  6. Rubbing Alcohol – If the fabrics still smell, soak them in a very weak solution of rubbing alcohol (99% isopropyl alcohol, 1/4 cup-1/2 cup in a bin of water). Vodka is the alternative.
  7. Machine wash with the non-toxic laundry detergent of your choice, using vinegar in the fabric softener compartment to neutralize chlorine and to soften. Lemon juice is the alternative to vinegar.
  8. Boiling clothing can make a huge difference as a last step, once the chemicals have been removed. The water may need to be changed several times.

Those less sensitive can use one or two of these soaks, starting with borax and washing soda, then vinegar, then salt.

Two more protocols designed by the most chemically sensitive people (but are simpler than the one above) are outlined in Substack. They can also be adjusted for those less sensitive.

    Great list! Formaldehyde tends to be one of the main chemicals I’m sensitive to. I often buy Oeko-Tex which is easy to get a hold of. Kohls Sonoma brand is one we buy often. We could go into the store until they installed the Sephora which stunk up the whole store so we order online now. I’ve seen Oeko-Tex in Walmart and Target as well. But, there are times I have purchased items that aren’t Oeko-Tex and I’ve tried most of these methods. I’ve noticed no diff using vinegar, borax, baking soda methods. I’ve also used a heavier laundry detergent like seventh generation and rewashing with our reg detergent. The boiling method needs done outside. The best I’ve that works is the milk powder. 1 cup in a tub FULL ( this does make a difference) outside for 3-5 hours, stirring every hour to make sure the clothes get submerged. Rinse and spin. Then wash with 1 c of baking soda and 1 c vinegar in fabric dispenser on hottest cycle the clothes can endure. I go ahead and dry but can hang out to dry if you don’t have allergies. Usually, 1 wash is all that is needed for us using this method.

    New clothes smell good to me, but thank you for sharing a way to remove that chemical. How harmful can it get to human health?
