I'll list a few tips here since I'm a clean freak lol
1. it's a good idea to have a weekly list of things you need to clean. like once a day sweep the floor, M/W/F mop the floor, T/TH dust everything, every Saturday wash bedding, every Sunday do laundry, etc. that way you can get into a routine.
2. every few months maybe just go through your stuff and see if there's anything you can throw out or donate. I'm still in the process of doing this and I've already thrown away tons of stuff and given 4 more boxes of stuff to goodwill.
2.5. it's a really good idea to detach yourself emotionally from everything since that can make it really difficult to throw stuff out that you actually don't need.
3. definitely invest in a good duster, especially if you have pets. my dog sheds constantly so I get a lot of dust in my room, I have one of those fluffy swiffer dusters and it works really well.
4. always keep some disinfecting wipes around. even if you don't think you need them it's good to wipe down stuff often, mostly stuff you touch a lot like computer keyboards, phones, gaming stuff, etc.
5. have a dedicated area for cleaning stuff so it's easy to access (makes it easier for people with exec. dysfunction, like myself, to clean without getting overwhelmed). I personally use the bottom drawer of a large dresser.
6. make sure you wash dishes daily, and get into a routine w them. I personally use dishes throughout the day and then wash them the following morning, but you could even wash them right before bed so they're done.
6.5 BIG TIP! make sure that you wash your dishes off
as soon as you're done using them!! as in, get any food particles off and rinse with water until at least mostly clean. this will make cleaning them later sooooo much easier and even if it sounds like a hassle it's very much worth it!
7. also I second what Kaiaa said, having just a few dishes is really helpful. I have 4-5 plates, one small pot and one big deep pan, 5-6 of each piece of silverware, and a few cups
8. always put something away as soon as you're finished using it, not only so you don't have to pick it up later but also so it doesn't get lost.
if I think of any more I'll post them for you
