New garden tiles need cleaned

Hi I have had my garden tiled and theres adhesive over a few of my tiles
Think it’s cola anybody have any ideas what’s best to remove this or know anybody than can do this job please

Agua fuerte is very good and mega cheap, it's an acid and can be bought in any supermarket.

Just a scraper, kitchen sponge scourer, and warm soapy water. Simple.

If you had somebody do the tiling ask them to do it.
