This may be too crazy... just made the hands with different color rubber gloves, but realize you might be after a more corporate look. Will keep thinking...
ok, my feeling is the logos are giving a "cleaning company" impression which steer us away from the target audience. they are all really nice. but SOMETHING IS MISSING .....
i'd not go with #46. Why? 'coz it is too detailed hence we will have trouble to portray the same level of details in our logos on small stickers or on uniforms .... am I making sense?
#45 giving too much an impression of a cleaning co.
my fave #16 is still not developed. how to develope it I am not sure :s
