What's the best way to scrub a bathtub?

Q: What's the best cleaner sold at a store to use to scrub the bathtub?
What works the best?
I need to get my bathtub to be white again

A: This may sound strange but I don’t use a special cleaner at all. First, put some really hot water in the bottom of the tub with a scoop of laundry detergent. I buy the big tub of commercial stuff from Costco and it works fantastically for all types of messes. Anyway, mix it all up, and then let it soak. Ideally, overnight. If you are okay with using a lot of water, fill it as much as you can or else just a few inches on the bottom. I have also used the water to wet a sponge and scrub the surrounding tile and shower but you can also make a paste with detergent too to scrub. It’s amazing cos it dissolves the soap scum so nicely. In the morning, empty the tub, scrub it lightly, rinse and check out the gorgeous shine. Mine just gleams after. Good luck!
