Ply is simply the number of layers folded into each sponge — more ply means more absorbency and cushioning. The 8-ply pieces (like the Ducare 4 x 4 Inch, 8-Ply Sterile, 82408 and its non-sterile counterpart 90408) suit lighter drainage and general prep, while 12-ply options such as the 4 x 4 Inch Sterile 82412 handle heavier exudate, wound packing, and cleaning.

Choose sterile sponges for open wounds, dressing changes over broken skin, and any procedure requiring an aseptic field. Reach for non-sterile versions like the 3 x 3 Inch, 8-Ply 90308 when you're prepping skin, applying topicals, or doing routine cleanup where individual sterility isn't required — they're the economical choice for high-volume, general-purpose use. Sizes range from compact 3 x 3 inch for smaller sites to the standard 4 x 4 inch that fits most applications.

Keeping both sterile and non-sterile Ducare on hand in a couple of sizes covers nearly every scenario a caregiver or clinician runs into. For broader options, browse our full Gauze Sponges selection, related Gauze Dressings, or the wider Wound Care category.
