Performance Repel Plus Clear vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Inhalation of spray aerosol / solvent vapors, Skin or eye contact with liquid formulation, VOC off-gassing after application and Water or soil bioaccumulation of active repellent on the Granger's 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 Granger's.
• The Granger's is Water repellent treatment (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 Granger's grade, at 35% confidence against 78%, because it discloses less.
