Depending on the level soiling that your briefs go through, and the time intervals you choose to wash at, your maintenance period will vary between 2 and 4 weeks.
The Protective Briefs are a separate animal from the Flexible Absorbency System, and although they both can be washed together, you may find the absorbency needs more maintenance than the briefs.
Cloth Diaper Detergent Build Up
Microfiber is highly eﬀective at absorption. It pulls liquid deep into its fibers, making it that “super absorbent miracle cloth” that Sham WOW made it famous for. This also can make it prone to build up. Regular washes can leave behind a very slight detergent residue. Drying the cloth can then solidify this residue into the fibers, which over time can lead to “detergent build up.” Detergent build up can be mitigated by running a warm water rinse, after your wash cycle, and ensuring you are washing with a high volume of water. Without a high volume of water in your wash cycle, the absorbent fibers will soak up the detergent that is meant to be agitating in your machine and performing the wash cycle. You can tell if you have detergent build up when the absorbency performance of your inserts decline.
