I deep clean once a week usually saturdays first thing in the morning so that it is off of my plate and I can enjoy my day. I tidy once to twice a day ( I have 2 kids) I generally try not to go to bed with a messy house. By tidying daily my deep clean doesn't seem so bad.
To be completely honest, I don’t have a solid deep clean routine in place. I try and keep my space as tidy as I can from day to day, which makes me feel like I can put off the deep cleans more, even though I know I should start establishing some sort of schedule to hold myself accountable.
