Description
This product is discontinued. Contact Chemical Concepts for a current alternative. Foster 40-80 Disinfectant is a ready-to-use cleaner, deodorizer, fungicide, mildewstat, and disinfectant for restoration, institutional, industrial, and building-maintenance work. The 5 gallon pail supports larger projects where crews need a consistent product for hard non-porous surfaces and selected porous or semi-porous materials covered by the current product label.
Foster 40-80 Disinfectant Applications
Foster 40-80 Disinfectant guidance covers washable hard non-porous surfaces such as floors, walls, tables, countertops, metal, stainless steel, fiberglass, finished woodwork, vinyl, and plastic upholstery. It also addresses odor-causing bacteria and fungi on porous or semi-porous materials encountered during water-damage restoration, including carpet, carpet cushion, subfloors, drywall, trim, and framing lumber.
Application methods include wipe, cloth, mop, sponge, or coarse spray. The surface must remain visibly wet for the full contact time stated on the current label. Published guidance calls for at least 10 minutes of continuous wet contact for covered disinfecting uses. Do not dilute the product, and do not apply it by fogging unless a current approved label specifically permits that method.
Use the Product Label as the Standard
Disinfectant performance depends on using the product exactly as directed. Confirm the target organism, surface type, cleaning step, application method, contact time, ventilation, and personal protective equipment against the current label and safety data sheet before work begins. Remove heavy soil when required, apply enough liquid to maintain wet contact, and keep people and materials away from the treated area until the process is complete.
The product data sheet lists a fresh, mild odor, an average density of 8.2 lb per gallon, and a pH range of 10 to 11. Application and storage temperatures should remain between 32 and 100 degrees F. The manufacturer states that the product should not be used inside HVAC ducts, vents, or on duct-liner insulation. Food-contact surfaces require particular attention to the label. Manufacturer guidance states that this product is not intended for food-contact surfaces in food-production facilities.
