How to remove stuck on rubber backing from painted sealed lanai floor

Try using an oil based product like olive oil and baking soda. WD 40 or Goo Gone might dissolve it then you could try using Bar Keeper friend to finish up.

I used WD-40 and steel wool to remove rubber backing from my hardwood floor. That should work for you as well but I would try a non scratch pad instead of the steel wool first since your floor is painted.

Try white rubbing alcohol.... Just pour some on a corner and let it sit for a few minutes and see if it will release.

Try using mineral spirits. I have come to love this product.

Maybe you could soften it with a heat gun and scrape it off with a plastic scraper.

Good Luck with That. I wanted to retile my bathroom floor. I proceeded to start removing the old vinyl tile. The tile came right up but the rubber backing and the glue didn't. I ask on here for suggestions on removing it and got a lot of answers. I tried all of them and was able to get the black rubber backing up but not the glue. I had to end up replacing floor with new Luan

I have use the Mr Clean Eraser for a lot of things and with the a light color cooking oil I bet that my be the deal water will just bead up but the oil will help to move the eraser around. And I bet it makes a mess too sorry! But it should do the job. Hope it helps. Teresa

Goo gone has worked for me on old paint and old glue. I’d try that first.

Use vegetable cooking oil - such as Canola, etc.
