Vivishine is an excellent rubber polish, very easy to apply, gives a glossy shine and durable protection. It is odourless and free from solvent.
Directions for use:
Wash your rubber in soapy water as usual removing all traces of dirt, lubricant etc. and rinse well.
Add 1 or 2 tablespoons of Vivishine (depending on the number of items) to clear water and submerge the rubber for a few minutes. Hang up to dry and store as normal.
