The last day of each month is a useful trigger for monthly tasks that are easy to forget.

End-of-month checklist:

  • Replace or clean the HVAC filter if it has been 30 days.
  • Clean the microwave with the steam method.
  • Descale the coffee maker with a vinegar-and-water cycle.
  • Wipe down the washing machine drum and door seal.
  • Clean the dishwasher filter.
  • Wipe down all large appliance exteriors.
  • Replace baking soda boxes in the fridge and freezer if it has been 3 months.

This takes about 45 minutes and prevents the gradual drift that leads to major cleaning days.
