Heat, cold, washing and exposure to solvent-based cleaners and run-of-the-mill treatments damage the finish of your vinyl upholstery and vinyl trim. Some vinyl manufacturing methods use formaldehyde as the base. Introducing solvent or formaldehyde-based treatments can accelerate vinyl deterioration by changing the original chemical balance. Zymöl Vinyl Conditioner is a solvent-free, formaldehyde-free, oil-based feeding product that releases solvents and restores moisture in all vinyl and plastic components.
