Waterproofing Wax for Leather vs FLY FREE ZONE Tuff Stuff 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 Tuff Stuff.
• We flag Volatile organic compound (VOC) / inhalation risk, Surfactant residue on fabric, Skin irritation from direct contact and Fabric or dye damage on the Tuff Stuff and not on the Nikwax.
• The Nikwax is wax-based waterproofing where the Tuff Stuff is liquid stain remover, surfactants and solvents, which is most of the difference in these two grades.
