There are different things in your home you should schedule out to clean or they get forgotten.
#1 Your Furnace Filters
Filters should be replaced frequently to help your furnace work at tip top shape. Plus with the fires in Colorado this year they are getting filled up more quickly.
#2 Your Oven
Sometimes you have to go for it and turn on the self clean.
#3 Steam Clean the Carpets
You should steam clean your carpets once a year and at least twice a year if you have pets.
#4 Wood Furniture
You should take care of your real wood furniture by oiling them 3-4 times (or more) throughout the year.
#5 Your Pantry
Take everything out of your pantry and wipe things down 1-2 times per year. Donate any foods you aren't going to eat and purge yourself of anything that has expired.
#6 Curtains & Blinds
Curtains and blinds get dusty and will need a deep clean 1-2 times per year at a minimum. Sometimes it is easier to simply start fresh with new curtains. Plus, it adds new pizazz to your house.
#7 Cleaning Your Walls
Walls get dirty and cleaning them and touching up with leftover pain 2-3 times per year will leave your home looking and smelling like new.
