cement on pvc window frames

Hi everybody, would anyone have any tips on how to remove dried on cement from pvc window frames, not a lot but unsightly all the same

Use an acid based stone or brick cleaner ( stone ex it think it is called ). Score the cement stain and apply the spray.Work into stain and wash off. May need several attempts but it will eventually break it up
