  • Excess sealant may be cleaned off tools and non porous surfaces whilst in an uncured state using Dowsil Universal Wipes or Dowsil Universal Cleaner. Care should be taken not to damage plastic or coated surfaces. Alternatively, cured sealant may be removed from non porous surfaces using Dowsil Silicone Sealant Remover.
