Adhesive damaged trim - advice appreciated

[Bobul]

I just had my bathroom tiled and there are patches of trim (gunmetal coloured alu trim from Wickes) which have been discoloured. The adhesive was Larsen. Any ideas what might have caused this? Have you come across it before? Thanks

I don't know what causes this but trim company's normally put on their labels to remove any excessive adhesive or grout as soon as .
