You filthy people! :D
Only jesting...... :confused:
My house has 7 animals.... :eek:
No, not really but we do have two dogs and a cat.
There is a lot to be said for poorly ventilated cases....
At least they do not get so dusty.... hehehe.
I clean mine everytime I open the case which could be once a week or once a month, suroprisingly (he says, taking the cleaning gloves off...) it does not get that dusty.
I think if you are really worried. Every other week sounds good.
