If You’re Wondering If DNase Really Works. . .

These socks are identical. I have about 40 surviving pair purchased between 2014 and 2018. They’re the Burlington no-shows Sam’s Club used to sell. The one on the left was a “clean” sock that got out of the rotation hiding with the black socks in the next drawer. I just found it an hour ago when looking for something else.

Since purchase, they’ve been washed exclusively on a hot heavy soil cycle, extra rinses, in either:

\* Tide Ultra Stain Release + OxiClean Free or All Free & Clear Oxi Booster, or Tide With Bleach (2014-2015)

\* Persil ProClean Liquid + OxiClean Free or All Free & Clear Oxi Booster, or Tide With Bleach (2015-2020 & 2021-2024)

\* Persil Accion Profunda liquid + Vanish OxyPower (late 2020-2021, Mexico)

\* Persil Advance Oxi + Odor and Biz, or Tide with Bleach (2024-June 2025)

I think most people would agree that is optimal care for white cotton-heavy athletic socks with Lycra.

Since June, the sock on the right been washed exclusively with 365 Sport Liquid + Biz. Same wash process. Based on my usual rotation they get washed about every three weeks after a day or less of wear. So they’ve had about twenty more wear/wash cycles, with ten more washes in the new chemistry, give or take.

The right sock was previously looking every one of its years and I’d been trying replacement socks to bulk-update the fleet. I knew I’d been seeing and feeling a difference with the change in wash chemistry but I am shooketh.

These have not been Spa Dayed. They’re displayed on white cardboard. Photo with an iPhone 16 Pro Max with flash, default settings.

Note this isn’t the sole of the socks with particulate soil. This is just sort of “normal yellowing” from being a ten year old pair of socks and someone with sweaty feet.

DNase truly removes the goo that makes white cottons look their age even with optimal washing.

(And yes, I think that is a quat spot on the right sock from being up against a bottle of conditioner in my suitcase at some point)
