Myth 2: Sewage-saturated carpets can be “saved” Absolutely not! Porous materials, such as carpet, pad, upholstery, bedding, wicker, paper goods, or fabrics that can’t be washed in hot water, must be disposed of safely. Myth 3: Partially sewage-flooded buildings are safe. Not unless contaminated areas can be sealed off to prevent cross-contamination of other areas. Only trained professionals using specialized equipment are qualified to restore sewage damage.
