FATSAC Mold & Mildew Prevention Sac Scrub is intended for purpose-specific cleaning inside fatsac ballast bags. Mariners Warehouse SKU 99766, manufacturer code M1081, supplies one 4 oz single-use bottle.
This lightly lemon-scented Sac Scrub is listed for FatSac cleaning and mold/mildew prevention. The 4 oz bottle is sold individually; the separately available 32 oz format is not included. The source explicitly limits this product to FatSac. Do not generalize it to other ballast brands, potable-water tanks, upholstery or cabin surfaces.
The listed purchase supplies one 4 oz single-use bottle. Separate accessories, treatment chemicals, applicators and larger package variants are not confirmed included. Match the exact care task and package before comparing related products or planning your order.
The store lists 4 oz per 80–90 gallons (650–750 lb) of water when the FatSac is full. Confirm the actual M1081 label and your FatSac instructions before dosing. A complete official timed process was not verified; obtain the required contact, draining, rinsing, drying and disposal directions rather than inventing them. A winter-storage cleaning claim does not establish freeze protection.
