Tide Washing Machine Cleaner with Oxi - Deep Cleaning Odor Eliminator for Front & Top Loader Washers (3 Month Supply) - Perfect for Monthly Washer Maintenance & Eliminating Musty Smells

Works perfectly. I just do a normal cleaning cycle with very hot water with no clothes and one of these packets of powder in the drum and all odors are gone and stay gone for many cycles.I have recently entered a mode of performing 1 or 2 laundry cycles each day with soiled clothes and bedsheets from elderly family members. Quickly the smell was nothing in the machine but also transferring to other clothes in the following cycles. I also think there was many years of buildup of humidity that went unattended because we didn’t know it was necessary. But if we left the wash in the washer for an hour or more after the cycle completed, we’d have a mildewy smell even after being dried completely.This product removes the residual odor using a normal wash cycle. I don’t bother with the special wash cycle with special soap that only works for my washer…I couldn’t even track it down since different soaps are required for different washers even from the same brand. Very confusing. This bypasses all of that and “it just works”.To start with I used a package after each heavily soiled load of laundry (about 2x per week). But that was unnecessary. I am now using it about 1 per month despite having so many heavily soiled batches per week.
