I use a carto for days or a week or in one case 2 weeks until it is too weak. Then I set it aside if it was a good one and still working. I may try to clean them. Some people have luck with that cleaning them. If cleaning doesn't work, no big deal - they cost $2 and if I even got 4 days out of it that's pretty cheap.
If if wasn't fully dry before you filled it, it won't work right. If it's nice and dry, you need to fill it fully to start and let it sit to distribute the juice through all of the stuffing. Then if it is functional it should either vape or seem like a flooded atty. If it seems flooded, make sure the air channel is clear, you can see through the air channel, any loose juice above the stuffing is sopped up (with a tissue if necessary) and try again.
And I don't use the condom method. I pop out the soft cap and fill into the stuffing which is why they have soft caps.
