Floor adhesive on tiles - how to remove

Relatively new floorboards and tiles but some excess adhesive from the boards are on the tiles and stuck fast attracting all sorts of dust/hairs etc.

Am scraping away with credit-cards but is there any faster solution ?

Is this tile adhesive? If so, you can get products like '' specifically for this purpose. Most builders providers, tile showrooms, DIY shops will sell this.

If this is wood glue on glazed tiles, then a ceramic hob scraper will do the trick.

remember you can tile on top of tiles! i dont think there is an easy option for this unless as previously suggested some type of chemical. maybe ask in a tool higher shop
