Waterproofing Wax for Leather vs Multi-Fabric Upholstery Cleaner Stain Remover: which is safer?

Where these two actually differ

• We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Resolve.
• We flag Surfactant skin and respiratory sensitization, 1,4-dioxane contamination in surfactants, Formaldehyde-releasing preservatives and Fragrance undisclosed allergens on the Resolve and not on the Nikwax.
• The Nikwax is wax-based waterproofing where the Resolve is liquid cleaner, surfactants and water-based formula, which is most of the difference in these two grades.
