Some waste disposers smell because food accumulates under the Splashguard, allowing bacteria from food particles to grow and generate odors. This cannot be cleaned with our competitor’s units without removing and dismantling their disposer from the sink. All Bio Shield disposer models have a Splashguard that is easily removed from the top of the sink for cleaning or replacing. Food odors are eliminated if this is done regularly. We also are the only disposer with Bio-Shield antimicrobial for odor protection. Our other products, including Mr. Scrappy Disposa Clean and Disposer Brush can be used for effective odor prevention (Mr. Scrappy Disposer Accessories).
