Fabric Protector Extra Strength 10-oz. Residential Use Standard Application Men's vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag PFAS-based repellency chemistry (fluorochemicals), Aerosol inhalation risk during application, Lack of ingredient transparency and Leaching or off-gassing onto skin-contact fabric surfaces on the 3M and not on the Nikwax.
• We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the 3M.
• The 3M is Fabric treatment coating, composition unspecified where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
• We are less certain about the 3M grade, at 35% confidence against 78%, because it discloses less.
