Care varies by product; follow the manufacturer’s instructions, but general guidance from product descriptions includes: spot- or wipe-cleaning some reusable warmers; washing replacement ice pucks with soap and water; and keeping unused breast sheet masks in their resealable packet for up to two days. When in doubt, consult the product label for specific cleaning and storage directions.

Hydrogel nipple pads are described as cooling on contact and can stay cold for up to 4 hours.

Both the perineal foam and pad liners are medicated with witch hazel. The pad liners specifically list Witch Hazel 50% and product descriptions note formulations without dyes or fragrances.

Reusable breast therapy packs are 2-in-1: they can be frozen for cold therapy or microwaved for heat, remain flexible when frozen for better contouring, are often teardrop-shaped for coverage, and are described as compatible with most breast pumps.
