Best tips are simplified Flylady techniques.
5 minute room rescue.
Set a timer for 5 minutes and whizz around tidying as much as you can. Go for big impact stuff e.g. in living area hang up coats that have been chucked on sofas, pair shoes, chuck out newspapers and any rubbish, put stray cups in sink or dishwasher. In bathroom, hang up towels or put in laundry hamper, polish taps and mirror, give loo a quick scrub. I have ADD and often find I have forgotten I was tidying a room before the 5-minute timer goes. If so, I just reset it. Sometimes I do 2 x3 mins if I am having a very distracted day.
You will be amazed at how much better a room looks after ionlhy 5 mins. It's a huge incentive to do it often.
15 mins to 'company ready' Pick one room or zone in the house. Set a timer for 15 mins, In this time you make that one room fit for inviting anyone into it. Empty waste baskets, plump up cushions, dust, hoover the visible bits of carpet give it a quick polish.
I now always keep my hallway tidy via 5 minute rescue and the living room and downstairs loo 'company ready' so that if anyone calls by unexpectedly, they are welcomed into a clean, organised space.
Finally 1-hour 'home blessing'.Get the whole family on board for 30 mins to 1 hour on Saturday or Sunday mornings. This is when you put on loud upbeat music, and everyone has a cleaning job - one person hoovers stairs and landings and their own bedroom. One person does living areas and their own bedroom. One person mops kitchen and cleans surfaces and sink, another does the bathroom. Everyone strips their own bed and puts fresh bedding on. It honestly takes about 30 mins if everyone mucks in. If they don't, just do a 10- minute room rescue in each of six areas,. If you do this weekly, along with 5 min room rescues whenever a room gets you down, you will notice the difference.
After tyhe home blessing do something nice - buy some fresh flowers or light a scented candle or brew coffee or bake a cake so the house is glowing and smells good, and the family can appreciate why it's worth doing. (And always say 'good job' and 'wow that only took half an hour!' to DC to reinforce how effortless it is to keep on top of stuff.
