You can use KBS #1 Thinner or lacquer thinner for cleaning up BlackTop before BlackTop cures.
For cleaning the surface prior to applying BlackTop, only use a water based cleaner like KBS Klean. Solvent based cleaners should always be avoided for cleaning prior to application because solvent based cleaners leave behind a reside which can hinder the adhesion and look of BlackTop.
TIP: Only use KBS #1 Thinner or Xylene when thinning or reducing BlackTop.
