When I first became a mom, there were 2 things we implemented which really helped in making the house look nice in just a matter of minutes.
1. Get a chamois (like what you use to dry a car), and use it on your shower walls after every shower. It will literally keep your shower looking like new.
We have used a chamois on the shower walls for over 17 years, and still, people will visit and say, “Did you get a new tub surround?”
Granted, if you take a lot of baths, the tub itself will still need cleaned, but at least the walls will look sparkly clean.
2. Get a feather duster. Whenever someone calls to say they want to stop by and visit, you can use the feather duster and be done “cleaning” in about two minutes.
