CLEARCOAT OVER BLUE CHALK LINES

THIS IS ONLY A PROBLEM WHERE IT CROSSES THE DOORWAYS. I USED A SMALL AMOUNT OF XYLENE WITH A RAG AND GOT SOME OF THE LINE OFF, BUT AM CONCERNED ABOUT PENETRATION INTO THE CONCRETE. WILL THE NORMAL FLOOR SCRUBBER W/ BLACK PAD WORK IF I MAYBE PRETREAT WITH XYLENE? ANY SUGGESTIONS WOULD BE APPRECIATED. THIS IS THE FIRST TIME I HAVE RUN INTO THIS PROBLEM.

You could also lightly hand grind the areas to get it but just be carful not to go too deep
