1 - why save all the washing until the weekend? I chuck a load on before work, come home 9 hours later and it's washed and dried. I chuck it on the bed and it gets put away before we go to sleep. Five loads a week roughly - coloureds, whites, bedding, towels and dog stuff.
2 - why on earth are you deep-cleaning the kitchen each week? Surely you just wash the dishes each day and wipe down the sides and hob as you go? Floors swept each morning? What else need doing on a weekly basis that's taking you so long?
3 - bathroom/cloakroom. Rinse the shower out after every use, squirt some toilet cleaner down the loo a couple of times a week and leave while you're at work, then brush and flush when you get home. Spray some cleaning spray around a couple of times a week and rinse with the shower head. Get some wipes and just wipe around the sink/sides after you've done your teeth.
4 - change the bed. This only takes five minutes, surely? Strip bed, leave to air. Change linen a few hours later.
5 - there is no way I would be dusting every week - maybe lower it to once a month? Surely two adults don't create that much dust?
6 - Hoovering - I have to hoover downstairs every other day thanks to the dog and cats. Takes me five minutes - upstairs doesn't need doing anywhere near as much because outdoor shoes don't go up there, and the cats don't go upstairs. Again, when I have to do the whole house it's only a 10-15 minute job. I do that maybe once a week/fortnight.
7 - dusting - again, why are you doing this weekly?!
8 - gardening - surely this doesn't need doing every week? Or, if it does, can you not hire a gardener?
9 - food shop. Do this online, or after work one day. Surely for two adults a weeks shop only takes half an hour?
I don't mean it literally takes 9-5 but it takes a good chunk out of a weekend day.
