Keep your kitchen clean. Put stuff away when you're done, wipe counters daily, clean out the fridge, do dishes, clean as you go when you cook. Laundry. Keep up with it. For a household of 2 you want to do it probably 3x per week. Change and wash bedsheets weekly. Hand towels too. Bathrooms. Clean weekly. Shower about 1x per month. Use clean shower spray. Keep the bathroom clean and you'll feel so good when you get out of the shower. Floors. Don't wear shoes inside. That's so gross. Sweep/mop/vacuum weekly. Dust. Dust at least every other week. Organize. When stuff gets messy, reorganize. These are the basics. More care as needed, depending on what you do/use the most. Basically keep everything as clean as you can. Also make the bed or at least straighten/smooth the sheets. It sleeps better.
