Boot print on new porcelain tiles

[Muj]

Hi guys,

I’ve recently (few days ago) had porcelain tiles laid in my garden. Like an idiot I must have walked on some cement/primer/unsure of the residue which has left a boot print.

I have tried washing it down with washing liquid and scrubbing it which hasn’t worked and today have tried HG cement remover which also didn’t work.

im now at odds as to what it could be and how I could get rid? I have attached a pic of the print.

I would appreciate any help

Thanks both, I have already tried the below:

HG Cement, Mortar & Efflorescence Remover - 1L | Wickes.co.uk

HG Cement, Mortar & Efflorescence Remover - 1L

www.wickes.co.uk

It had no effect at all, does anyone suggest a different cleaner?

Scotchbrite and elbow grease, wet and dry paper not too course. nothing too agressive though as those porcelain tiles don't seem very servicable to me. You can't even give tham a blast with a pressure washer without damaging them as far as I know.
