The ported bottle can be handy, but many folks I've talked to who have them don't think they're worth how much they cost.
Make sure you have the right carboy cap or stopper to fit in it.
Get some oxyclean to wash it out with. Much easier and you don't have to worry about scratching. Just add a scoop of oxyclean, fill with hot water and rinse a few hours later. You don't want to use a brush in a better bottle.
