I use any clear gel, currently Old Spice. I haven't found a single "normal" deodorant that doesn't leave white shit on my shirts, so clear gel it is.
As for shower gel, I just use a bar of soap. Anything is fine. What you should be really worried about is your shampoo and conditioner. Don't use either of them daily. Don't get that bullshit 2-in-1. Most people use them wrong, too.

I mean, I like being told about new features rather than needing to discover them myself twenty months after they came into existence
