Reputable uk restorer

Hi everyone. Are there any tried & tested uk companies that have good reputations with the turnaround & the quality of the work done on restoring/fixing Balenciaga bags? I’ve come across the Handbag Clinic and the Handbag Spa but I’m unsure about them.

I need the corners of a bubblegum pink to be cleaned up as they’re quite grubby & I don’t trust myself to do it & not destroy the bag Thanks :smile:
