A dry cleaner’s guide to giving secondhand clothes another life. This shirt had yellow underarm sweat stains, old oxidized food stains, and mold. Here’s how I brought it back.
1) Loosen it up. Spray the shirt with water and a little dish soap to start breaking down oils and grime.
2) Pretreat. Apply an enzymatic pretreatment to the underarms and old stains, and a sanitizing spray on the mold. For best results, let these sit for a few hours before washing.
3) Build the wash. I added my powdered booster mix (borax, washing soda, and sodium percarbonate), an oxygen bleach to whiten and brighten, a high-quality detergent, and a sanitizer in the rinse slot because of the mold.
4) Run a sanitizing cycle. The high heat kills mold spores and helps the oxygen bleach work at full strength.
5) Touch up. It looked great out of the wash, but I applied 3% hydrogen peroxide to even out a few remaining discolored spots.
6) Dry gently. Air dry indoors or in the shade.
7) Bonus experiment: I rarely talk about liquid bluing, so I tried it here. Bluing is basically makeup for clothes. It adds a trace of blue that makes whites look brighter and less yellow. Swipe through the before and after. Can you see a difference? Let me know in the comments.
This banged-up shirt has officially been given a new life. Hope you found this helpful.
