Wiping down counters and washing dishes is supposed to get things clean. That's true as long as you don't let that rag or sponge get too nasty. You'll end up spreading more ick that way.

Sponges pick up bacteria if they're not cleaned right. Zap a wet one in the microwave for 2 minutes every day and replace it every 2 weeks. Better yet, use cloths, towels, and rags that you can toss in the washer or clean with bleach.
