OP, I LOVE that you are in the search for cold-hard facts to win your case 🙂
In this instance, I am not sure if proof is in the research, but rather your own personal wishes…which, IS the problem here, obviously. I think you could ask bees how often they clean their homes, set-up a poll on here, and then show your DH what our opinions are.
With cleaning, there are SO many factors!! Small home vs large home. Pets vs not. Those that cook vs. those that enjoy eating out…ya know?!
For my FI and myself, our stats are as follows: We have a 2-bathroom, 3-bedroom ranch-style home with a finished basement. We also have a dog. So, for us, our ‘normal’ is the following:
Deep clean every two weeks. I wash floor mats, bathroom hand towels, shower curtains, bedding, SCRUB the kitchen, bathrooms, floors. Dust surface hours, etc. NOW, I do not do every room when I do this. My two spare bedrooms get a quick dust monthly, and I only wash the bedding before/after guests. Why bother?! NO ONE ever uses it otherwise. And our finished basement gets cleaned once a month too. We do not spend a ton of time down there, but if/when we have kids, I am sure that will be added to the bi-weekly list.
Daily, I de-clutter, wash counters and stove down (because I cook MOST nights), wash the sink out, and quickly wash down the main bath sink bc I hate hair, and its everywhere. We vacuum every 2-3 days due to our dog, but her fur blends with our carpet, so it does not bother me daily 🙂
THIS works for us, because we do not have a ton of house, so deep cleaning only takes a few hours, rather than an entire day, and keeping things organized makes it feel bigger, imo. I am TYPICALLY the one doing the cleaning, but I do not mind bc Im picky, and would probably not like the standard FI does it in. Furthermore, he does all outdoors work, and we have a large yard, and multiple gardens to keep up with too. We split the laundry. He does mid-week loads, and I do weekend loads. I think it works out for US in the end, but everyone needs to figure out what works for them too, etc. I wish you all the luck!!!
