A paste of baking soda and vinger.
Fine wet sandpaper
I use baking soda to clean my acrylic tub/shower. It gets out a multitude of stains. Maybe it will work on this
I've been using white vinegar.
Once the old tub gets into the drain it is impossible to remove.........

Baking soda is perfectly safe to clean just about anything.
try two things....one buy soft scrub with bleach and try using it to bleach out the color of the tub. if that doesnt work...try using kaboom. i swear thay gets anything out of the tub. ether or, let it soak into the color to try and help your problem.
By disconnecting the tub shoe from the waste tee and removing tles around the tub
By un surrounding it
If you have city water (decent city water that is) a fiberglass unit with typical warranties of approx. 6 years, will do you just fine. Acrylic is best for places with well water and have typical warranties of about 10 years. The difference is that acrylic fiberglass is solid throughout, whereas what is known as a fiberglass unit has what is essentially a spray coating of acrylic on the surface. Thus the solid acrylic fiberglass units are "tougher" It is recommended for either unit to use something like car wax (on the walls ONLY, never the floor, unless you use non-slip mats) to protect the unit, at least once a month.
Pop them. Tediously. One. By. One.
