question about co2 tanks

[the_mox]

hey guys,
I have a co2 tank with a company sticker on, got it from a guy, who bought it from them. i know some places wont refill/exchange a tank if it has another companies "stuff" on it. should i remove the sticker before i try to have it refilled? or am i just being over anxious? this is the first time i've dealt with getting a co2 tank refilled...and dont want to waste a trip, because its not a quick drive.

I had a 20 pounder with Pepsi sticker on it I just took it off and cleaned up the area and took it to the welding supply shop and exchanged it no problem for me when I did it
