Even if you use your food sealer rarely, you will want to clean it after each use to eliminate the build-up of bacteria. First, you need to unplug your unit. Then, use a damp rag, sponge, or towel with antibacterial soap to slowly wipe down the sealer. Make sure to wipe the buttons and the vacuum channel well. Then use your damp rag to remove the soap, dry with a clean rag or towel, and plug your sealer back in when it is thoroughly dried.
