Hi
@Annette22 Following on from your posts on the cage cleaning article and how to clean the pee for Mindy without stressing her

I suggested posting on here because I was going to write a long post! And also comments on the articles go for moderator approval (which you probably noticed!).
Is she at the point where you could have her out of the cage yet? If it's stressing her having a spot clean of the pee (presumably you have to dig down t find it) then one way is to do while she's out of the cage. So she doesn't see what you're doing. Eg in a playpen area. So I sometimes offer them a tube with a treat in (they tend to walk in to get the treat), keeping hands over both ends of the tube and carry them to the playpen area. If it's a bit of distance then rather than carry the tube all that way, you can have a large box on the floor next to the enclosure, put the tube down in that (so she can come out of it) and carry the box to the playpen area. Then you just gently put the box on it's side inside the playpen so she can walk out.
Spend a bit of time talking to her in the playpen (maybe try offering some food on the palm of your hand as well) and have a few things to do in the playpen. Providing it's secure, or there's someone there to keep an eye, then after 10 minutes or so you can leave her, go to the enclosure, spot clean the pee, try not to have too much collapse in that area. Maybe add a couple of special treats to the cage (to distract her from the change), wash your hands (obviously!), then go back to her in the playpen, spend another 10 mins or so talking to her. Offer her the tube again (they usually walk back into it and this gets them in the habit of walking in a tube and seeing it as a taxi), and then transport her back to the enclosure again. Still keep one hand over your end of the tube and let her walk out of the other end back into the enclosure. Let her out near one of the treats! She will immediately go for that and then maybe sniff out the other one (add a few if you like). Maybe a bit of fruit, some scattered pumpkin seeds, half a walnut eg.
She will at some point notice something has been disturbed and she may look a bit miffed or slightly stressed and start putting things back how she wants, but she will be less stressed than if she was there while you were doing it - possibly!
Hamsters vary - some are better in the cage when you do it, so they can keep an eye on what's going on (they tend to follow your hand anxiously!). Others, if they get stressed by that, are better having it done while out of the enclosure
You were asking if you should leave it for two weeks. To be honest, if she has deep bedding and you can't smell anything, then leaving it a couple of weeks can be ok because she is likely to not sleep where she is peeing. And some hamsters will chuck out the smelly bedding themselves and you find a pile to take away. If she's still settling in, then she is going to react more to spot cleaning than if she has adjusted more to her new environment
They do give us some worries!
Or - you could try the treats in the cage while you try and spot clean (if you can find the pee!).
Does she pee in a sand bath at all? Another thing you could try is adding a potty/litter tray with sand in - either near where her burrow is, or, inside a multiroom house if she has one. And put a bit of wee'd on bedding on top of the sand so it smells like a toilet! She may or may not use it.
I tend to find that if they use a multiroom house (eg sleep in it or burrow under it) then they will use the litter tray inside it. But if they have a burrow somewhere else, they tend to pee underground - which is harder to spot clean!
It'll get a bit easier each time, as she'll get used to it
If she's sleeping in an inconvenient place then you could try
a) Tempting her to move into the multiroom house (not always easy) - eg leave a trail of treats up to the entrance and a smelly treat right inside and a bit of food - eg cucumber or a tiny bit of cheddar cheese.
b) Moving the multiroom house over the top of her burrow - so she comes up inside it - and putting the toilet in one of the rooms.
