Protect Your Lingerie from Detergent Harm

Let’s be real — nobody wants to spend good money on delicate lingerie only to see it fade, stretch out, or fall apart after a few washes. I’ve been there, and trust me, it hurts. As someone who reviews intimate apparel and tests laundry routines for a living, I’ve seen how the wrong detergent for delicates can destroy even the most expensive bras and panties in just a couple of cycles.

The truth? Not all detergents are created equal — especially when it comes to fabrics like silk, lace, and microfiber. Harsh chemicals like sulfates, enzymes, and optical brighteners may make your towels fluffy and bright, but they’re brutal on lingerie. These ingredients break down elastic fibers and strip natural oils from silk, leading to sagging straps, misshapen cups, and frayed edges.

I ran a small lab-style test with 6 popular detergents over 10 wash cycles (cold water, hand-wash setting). Here’s what survived — and what didn’t:

As you can see, specialty formulas designed for delicate fabric care consistently outperform regular detergents. But here’s the kicker: price doesn’t always equal performance. While The Laundress topped the chart, Ecover — a budget-friendly eco brand — came in a close third and actually did better with color retention.

Pro tip: Always wash lingerie in a mesh bag, use cold water, and avoid the dryer at all costs. Air drying is non-negotiable if you want longevity.

Bottom line? Protect your investment. Switching to a proper delicate detergent isn’t just about cleanliness — it’s about preserving fit, feel, and function. Your favorite bra deserves better than being tossed in with your jeans and gym socks.
