Never use brass cleaner on a saxophone! The harshest you can possibly use is jewelry cleaner such as Wright's silver polish or tarnish remover but even that only on very rare occasions.
For daily cleaning and maintenance, charcoal lighter fluid as suggested by Steven, and WD-40 in its various branding iterations are good choices. And do not add any oil to the tenon either, the combination of oil and dust is called lapping compound and it is the last thing you want to apply to your tenon unless you go for that airy sound caused by a tenon leak 😎
