I know that my house isn't truly dirty. Firstly I do TOMM so everything gets a clean weekly, I vacuum downstairs daily, change beds regularly, mop hard floors weekly, dust, wipe kitchen cupboards down and so on and so on.
But it feels that no matter how much effort I make to keep it nice and clean it's very 'lived in'. I know that there's nothing wrong with that, it's not a show home but I do find it hard to relax with mess around.
For example there is permanently washing on airers hanging around, toys out that get put away each evening, the kitchen is in constant use with 4 of us here and one teen who never stops eating. We cook a lot so obviously kitchen gets heavy use.
No sooner have I run the vacuum around or wiped down the kitchen worktops bits appear on the floor just crumbs and bits.
