Deciding what to keep is on you...though light.gg is a good website that will tell you a weapons possible rolls, and what perks the community in general tends to favor. It wont tell you what to keep, but at least you'll have better information at hand when making your decisions. As far as actually DOING the cleaning though, I am a fan of the 'ishtar commander' app. It's great for inventory management as well as building and saving loadouts that can be equipped on the fly right from your phone/device. Best part is it will let you access your vault and loot on all your characters without even signing in to the game. Edit: the ishtar commander app is also handy for viewing the 'hidden' stats on your weapons (like recoil direction) which are not directly viewable in-game

Isn't what you should keep a personal choice? I mean, everyone knows what God rolls are but then it's about keeping others that are just preference or specific to a certain build you're running. An app wouldn't know that.
