Use nail polish remover.
Use a little acetone (polish remover) in a well-ventilated area. One problem with this is that acetone (or other nail polish removers) can also dissolve a lot of plastics. If the tub is important to you, you might want to try it on an inconspicuous location first.
If it is just a fiberglass bath tub, you can just use nail polish remover.
If you mean how to make it. Get a small round tub of room temperature water. Choose your nail polish colours. Drop a drop of polish into the water. It should spread out. Then drop a drop of the other polish. Carry on until you think it is enough. Get a toothpick and draw your pattern then dip your nails in and remove the left over polish
Once the old tub gets into the drain it is impossible to remove.........

if the bathtub is painted i think that acitone will take off the paint! tyy nail polish remover
If you can get some Zippo lighter fluid it works well on sticky tape residue. Fingernail polish remover works too but with more elbow grease. (scrubbing)

Hot tub chemical's
Remove cat feces by turning the hot water on and let it run until it is hot. Then, plug the tub and fill it with hot water to the level of the stain. Put 1/2 cup of dishwasher detergent (not dishwashing liquid) in the hot water and mix it around. Let it soak overnight. It may need a light scrubbing when you drain the tub. A piece of 600 grit wet/dry aluminum oxide sand paper can also be used to wet sand the area. When the tub is clean, coat it with Rain-X windshield glass protectant. It may take a few applications since fiberglass tubs are porous. This will help the tub stay clean.
