It's tough isn't it, you spend all week working then all weekend preparing for the next week.
Laundry - I try and do a load at night or set a load off in the morning. I also try to hang a load out in the morning if there's one. I try to hang things on coat hangers when I put them on the line so I can put them straight in the cupboard when they are dry.
Bathroom - I keep a cleaning cloth in the bathroom and give the sink a bit of a wipe down if necessary. To clean the toilet I get some toilet paper and give it a dust and clean.
Kitchen - I've given up
Groceries - if I was organised I would buy them online during the week. Can you designate one evening a week to go grocery shopping?
If you can afford a cleaner and/or someone to mow the lawns every couple of weeks it would be of great benefit too.
