Trying to permanently remove the 40 year old bathtub clings put down in the bottom of the tub and shower to prevent slips and falls. Help! I can't even come up with the name of the stupid things! Rubbermaid manufactured them, they look like daisies, footprints, fish, etc.
I have the same problem and posted on a forum in which the members primarily use green and homemade forms of cleaners. I believe white vinegar was one of the suggestions, but several also suggested oils, such as baby oils, to loosen the decals/clings. Then use a plastic putty knife, or something with an edge hard enough to scrape but not hard enough to damage the bathtub finish.
You might want to try scoring the tops of the stick-ons and spray WD-40 on them and let them set for a few hours. Then try to loosen the edges and remove. It might take a couple of attempts.
Goo-Gone which is an adhesive remover might work as well, too.
i don't know what the name is. i have used this before and it is great it is a bar of a kind of pumice.it is hard like a rock,but you can rub it on porcelian and it wont scratch. i got it at a plumbing supply house. 8 inchs long and 2 inchs square i cleaned a old tub,that was said could not be done. it had a bath ring,10 inch's wide,all the way around. around the drain was dark brown but get the stone wet and rub,
It is called a Pumice stone frodo, common brand name around here is "Pumie, scouring stick". Usually found in the cleaning isle at the home / hardware stores and some grocery stores. They are great. (get one even if you don't use it on your tub)
And I think it was what got the last of the ahesive off our tub from those darn non slip stickers....about 20 years ago.
Make sure you are dealing with a porcelain tub, and have enough water in it to cover the bottom, while you work with it.
