When filling sealant into brand-new tyres, Muc-Off recommend degreasing the inside surface of the tyre to remove any oils or mould-release agents/residues from when the tyre was manufactured. For the best results use their Quick Drying Degreaser, Disc Brake Cleaner or Glue and Sealant Remover, along with a clean cloth for effective cleaning. This process ensures maximum adhesion and effectiveness of the sealant.
