Nasty Toilet Cleaning

Nasty Toilet Cleaning

[Let me preface this with saying I'm pretty much a beginner at cleaning.] So I live in a house with 7 people. But I share a bathroom with 3 guys. Yes. 3 guys and 1 girl in one bathroom. It is enough to make any girl want to vomit upon entrance. My fiance (1 of the 3) is actually one of the cleanest guys I've ever met. He's really great about the bathroom, especially about keeping the toilet seat down, which the 2 other guys refuse to do. My question for you domestic goddesses is... What are the best products for cleaning nasty nasty toilets? We all rotate bathroom cleaning weeks, but the guys slack and usually don't do it. So I basically do the cleaning. I've never had to clean the toilet before. And this toilet gets particularly funky every week. So what products are really good to use? Also, what other supplies are helpful in cleaning the toilet. We have a toilet brush, but it seems pretty old and lame. Do you have toilet cleaning routines? I want to get the toilet as clean as I can, and would love some recommendations on products or toilet cleaning routines. Thanks!
