To ensure a long and healthy lifespan for your boots, wipe clean and leave to dry naturally away from direct sunlight or artificial heat sources such as radiators, hot pipes and stoves (heating will cause the rubber to crack). Only use cold, soapy water to clean the boots. Never use solvents. Never store boots whilst damp, folded or creased. Keep in a cool, dry location. Warranty is not applicable to boots that have been damaged by the use of a metal boot pull. Occasionally, you may notice a white powdery "bloom" on your rubber wellington boots. This is quite common in natural rubber and will not affect the performance or durability of your boots. We always recommend the use of a silicone welly oil for your boots. This will help to stop premature cracking, and help keep the natural rubber supple.
