Hoping somebody could suggest how to remove creases in curtains

Throw it in the dryer on low setting.

I don't, I just let them fall out. The steam and heat from the shower seems to do the job.

put it in the dryer for a few seconds

Put in the dryer for a few minutes or hang in sun till they melt out.

Turn on your hot water in shower and close the door..The steam should do the job.

Wash it with towels, then separately throw in the dryer on medium for only about 2 minutes. It will come out like Taffy. Then hang it up or fold it. Good Luck.

Hair dryer on low. Don't stand in the tub!

The dryer does a great job! If your curtain has a funny odor (they sometimes do when new), toss it in with other laundry then in the dryer with the same load. It won't damage it, however, make sure there are NO other items in the load that have zippers, buttons, etc. If the new curtain doesn't smell funny, just dunk it in some water, squeeze as much water out as possible and toss in the dryer with a few clean hand towels for a few minutes. It only takes two or three minutes to remove the wrinkles. Don't leave the shower curtain in for too long - it's not necessary.

Throw it in a warm dryer for a few minutes. The folds will come right out. Hang immediately while still warm , before it wrinkles when it cools down.

Time normally is all you need for gravity to do your work. If still there after a few showers, try pointing the shower head at the curtain while running hot steamy water. Or set your iron to steam the creases by holding the iron a few inches away. DO NOT TOUCH THE IRON TO THE PLASTIC. Be careful to keep the hot water and/or steam away from you.

Throw it in the dryer on med heat for about 4 min or so,,,keep checking it so you dont melt the curtain as you may have to go longer! good luck.

You could try hanging them and heating them some with a hairdryer so as not to melt them and see if they would fall just from being warmed up with the hairdryer.
