How do you prevent rubber seals from becoming stiff and brittle? The easiest way is to use the edding 8150 oil maintenance marker with silicone oil every once in a while on them. It’s ideal for keeping all types of rubber seals protected – be it on doors, fridges or windows. In addition, it can also be used to keep your car’s doors from freezing during the winter months, since it has anti-frost-protection. And during the warm summer months it keeps seals from porosity.

Being a truly versatile tool, you can even use it on plastic items such as suitcases or ensure that wooden or metal drawer runners seamlessly glide in and out. The edding 8150 is nearly as flexible in its areas of use as the seals that are treated by it.
