Does an Extra Laundry Rinse Help Eczema?

Your shirt feels fine when you put it on, but by the afternoon you want to take it off. You have eczema, and you wonder whether something left in the fabric is bothering your skin. The washing machine’s extra-rinse button offers an easy change. What can you expect from it?

What the current advice says

The American Academy of Allergy¹, Asthma & Immunology recommends fragrance-free laundry detergent and suggests considering an additional rinse if clothes still irritate your skin. Its patient page, dated June 2026, presents that as practical skin-care advice. It does not give a measured improvement rate or a number of rinse cycles guaranteed to help.¹

That wording matters: consider an extra rinse when there is a clothing problem. It does not say everyone with eczema needs to run every load through two rinses.¹

Why the evidence needs a date attached

A 2014 guideline reviewed adjunctive approaches to atopic dermatitis in children and adults. It reported too few clinical studies of laundry techniques, detergents and other laundry products to recommend a particular method as treatment. Double rinsing was one of its examples.²

The literature searches for that guideline ended in 2012. It describes the evidence available then, not a completed review of every study published since. The newer patient advice and the older guideline answer different questions: what someone might try for irritating clothes, and whether a specified laundry method had enough clinical evidence to recommend for eczema treatment.¹²

Neither source supplies a brand ranking or a promise that another rinse will stop a flare.

Check the detergent and the clothing

The American Academy of Dermatology³ advises using fragrance-free, dye-free detergent and washing new clothes before wearing them. Its eczema advice also addresses fabric and fit: loose cotton clothing, avoiding wool against skin, and removing irritating tags. The detergent is one part of what touches you.³

A new detergent, a tight seam and overheating can arrive together. The same dermatology page notes that overheating and sweat can trigger a flare. Changing the rinse cycle alone does not separate those possibilities.³

Our fragrance-free versus unscented article explains why those label words deserve attention.

The play

Try this: record one laundry change

If you decide to try the extra rinse, keep a short note of the detergent name, garment, wash setting and date. Record where the irritation occurred and whether you also changed the fabric, moisturizer or prescribed treatment.

Changing one laundry step at a time makes the notes easier to interpret. Feeling better afterward does not prove that detergent caused the symptoms or that an allergy has been identified.

Keep the eczema plan in the picture

Ask your clinician about clothing irritation that persists despite these adjustments. The allergy academy recommends an individualized skin-care plan; the dermatology guidance includes managing triggers and medication or phototherapy when needed. A laundry adjustment belongs alongside that care.¹³

Skin, Head to Toe uses the Skin Sort to organize details such as where dryness occurs, when it changes and which products changed beforehand. Chapter 5 also describes keeping the product routine short and changing one item at a time. Those notes can help you describe the laundry question without assuming you already know its cause.
