Remove sticker kolam from tiles flooring

I too have an old kolam sticker outside the main door. don`t know how to remove it. Someone please suggest.

 

this is what i did.. you get a spirit cleaner in the hard ware shops..soak the edges around the kolam with this..use a scrapers like your dosa spoon, that will not leave scratches, after a few minutes..it should start coming out easily..if you can get yourself a putty scraper, my carpenter suggested that easily cleans off the residue on tiles without scratching, if you learn to handle it..

you can use the same a few more times to get the tile back to normal...
