Waterproofing Wax for Leather vs Original - 24 oz Spray Bottle - Simple Green - Qty of 6: 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 Simple Green.
• We flag Caustic alkalinity (undiluted concentrate), Inhalation irritation from spray application, Spray bottle plastic degradation and Surfactant residue on food contact surfaces on the Simple Green and not on the Nikwax.
• The Nikwax is wax-based waterproofing where the Simple Green is Aqueous cleaning concentrate, surfactants, water, which is most of the difference in these two grades.
