Waterproofing Wax for Leather vs Armor All Tuff Stuff Stain Remover Multi-Purpose Cleaner: 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 Organic solvent volatility and inhalation risk, Skin and eye irritation from surfactants, Fragrance allergens and undisclosed additives and Residue buildup on upholstery if over-applied on the Tuff Stuff and not on the Nikwax.
• The Nikwax is wax-based waterproofing where the Tuff Stuff is liquid cleaner concentrate, surfactants and solvents, which is most of the difference in these two grades.
• We are less certain about the Tuff Stuff grade, at 40% confidence against 78%, because it discloses less.
