What knd of tub is it? Cast iron or fiberglass? The type of tub would dictate the recommended cleanser. Because fiberglass can be easily scratched, baking soda seems to be the less offensive of all the mild detergents listed in the resource below.

“For stubborn areas, such as bathtub rings, you can make a paste out of baking soda and a little water. Wet down the tub’s surface and gently rub the paste onto it with a sponge, soft nylon brush, or cloth.”

I use a foam bathroom cleaner - and a long handled scrubber. Spray on, let the product do the work - about 5 minutes. Then I have some scrub water with pine which I dip the scrubber in and then hit around the sides. Very easy on the back. Comes out perfect every time.

Get a water softener, so few ever think of this, my business for 20 years. MANY of the questions in this section would be solved with the use of a water softener.

we have a full service gas station.. I fought rings and stains for years.... just discovered a product called Awesome ( I buy it at the Family Dollar in my town)... it is just that Awesome... some folks use the Simple Green from the auto dept at Walmart,,, I have not tried that... I also use some of the Awesome in the wash along with my detergent to get the grease out of his work clothes..... can not give it enough praise.

You do not want to use anything that is harsh that may damage the finish. I use Lysol Bath Foam and my tub is 25 years old and still looks like new.

Fill your tub with hot water and put in a packet of bio detergent and leave For a while. Let water out then rinse off then polish with a dry old towel. That should work but it depends on how long it’s been since the bath was last cleaned.
