You've made me realise how much I prioritise this. As I said on my last post, I'm not posh. I earn minimum wage and live in a rental flat. I can't stand smelly or dirty homes though, I can't relax there, so I've subconsciously prioritised cleaning.
OP, if you're interested, this is how I manage it.
A pile of clothes laundry is done and dried daily so it never builds up. I haven't always had a tumble drier so if I've had to put the radiators on to dry it, then open the windows wide to let the damp air out after, that's what I do. Rooms aired each morning even if it's minus degrees outside. Liberal use of the power boost feature on kitchen and bathroom fan, after rooms have been used (window will be open too). I'll air the living room (where we eat) while bath time happens before bed, to get rid of lingering food smells. Countertops wiped down after food prep every time. Washing up done each night.
I allocate one of my days off to clean and I clean everything. I don't go out that day, I'm unavailable same as if I was at work. Beds stripped, aired, fresh bedding on. Bedding washed and either line or tumble dried. Towels washed and dried. All hard floors swept and mopped. All bins emptied, cleaned and new bin bag in, even if they're not full. Door knobs, handles, rails, skirting boards and all flat surfaces - including the bottom ledge bit on window frames, the recessed square pattern on the front door and the tops/bottoms of picture frames - wiped. Everywhere hoovered. I have either furniture raised off the floor that's easy to hoover under or furniture that comes down to the floor so no dust can get under it. Everything wiped down in kitchen and bathroom including tiles, appliances and cupboard fronts. Fridge cleaned out inside, no mouldy things left festering.
We live in a spacious flat by choice because it's smaller so is quicker and easier to clean. I can do it even with regular short breaks and interruptions without feeling like I'm busting a gut to get it all done, which is what it felt like when I lived in a 3 bed semi-detached house. No gardening here either.
We don't have pets because I can't see how to fit in looking after them properly and keeping their stuff clean, I believe the home needs hoovering every day when you have pets too. I did share a horse for a while. The coat and boots I wore at the stables stayed there and never came home. I had a coat and shoes for driving to/from and they weren't used for anything else, staying in the entrance porch cupboard and never coming further into the flat unless it was to go in the washing machine. My regular clothes/coats/shoes didn't go to the stables, I kept old tatty clothes for that. They were removed on coming home, went into the laundry basket and I'd go straight into the shower, so home never smelled of horses.
Now I think about it I suppose it is a lot of effort. Many people would rather live somewhere bigger or use their time/money for nicer things than cleaning and it's more important to them to have pets than a pristine home, that's fine, but it's not for me. My home being properly clean gives me peace.
