I would be hesitant to use bleach around my tank aat all, I just use a microfiber cloth dip a corner of it in the aquarium water and thats it, it may not be spotless but I feel safer not using any chemicals around my tank.
I think there is a spray thats safe for that kind of things and the glass hood filter covers everything safe for aquarium use at that fish place just a bottle of whatever but I would feel safer using that I do not know how much it is I am sure it not to expensive.
