SkyKleen 1000 has been found to be a superior product for the removal of cured polysulfide sealants, commonly used through the airframe and has been approved to the Douglas CSD-1 type 3 specification. Attacking the adhesive bond between the sealant and the surface to which it has been applied, SkyKleen 1000 allows lifting of large patches of sealant at a time.

Apply SkyKleen 1000 to the interface of the sealant and the airframe surface. Using the standard plastic or wooden scraper, pry the sealant up using a back and forth motion allowing the SkyKleen 1000 to flow to the front of the scraper. For thicker sealant layers a pre-soak period is recommended.
