You can spot clean daily if your ham doesn't use a litter tray or pee in the sand, just clear any damp areas.
Do partial cage cleans, with your size cage half at a time would be plenty, even a third, once every few weeks would be adequate.
If you clean the nest area always put some of the old nest back & never remove all of the hoard, if it looks old or has some fresh foods in there then just replace it with some fresh dry mix.
Don't use sprays for cleaning unless one of your hams is ill, really all you need is water & a paper towel, if you do need more than that always use an unscented pet safe disinfectant & rinse well afterwards.
