WD-40 Multi-Use Product EZ-Reach Flexible Straw 14.4 OZ Twin-Pack
Lower concern. Lubricant spray itself poses minimal risk; category mismatch noted.
WD-40 Multi-Use EZ-Reach is a petroleum lubricant spray with no PFAS-related formulation. No public disclosure or testing addresses PFAS.

What WD-40 Multi-Use Product EZ-Reach Flexible is made of, ingredients and materials
WD-40 Multi-Use is primarily mineral oil (a highly refined petroleum distillate) mixed with volatile organic compounds (VOCs) as solvents and liquefied gas propellant (typically butane/propane). The formula is designed for lubrication and moisture displacement, not direct skin contact or ingestion. When sprayed on furniture, the volatile solvents evaporate rapidly, leaving behind a thin mineral oil film that does not harden or cure like a coating product would.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Volatile organic compound (VOC) inhalation
Mineral oil solvent vapors are released during and immediately after spraying. Short-term inhalation in poorly ventilated spaces may cause respiratory irritation or dizziness; no chronic health signals are established for typical consumer use patterns.
Propellant flammability
Butane and propane propellants are flammable. WD-40 aerosols carry standard flammable aerosol labeling and should be kept away from ignition sources; accidental ignition of spray cloud is a documented but rare consumer risk.
Skin and eye irritation from direct contact
Mineral oil and solvent mix can cause mild irritation if sprayed directly onto skin or eyes. Product SDS recommends rinsing with water; serious injury from incidental spray contact is uncommon but documented in accident reports.
Mineral oil ingestion (incidental)
If sprayed on food-contact surfaces or ingested directly, mineral oil is a mild laxative and may cause digestive upset. No toxic heavy metals or persistent bioaccumulative chemicals are recognized in the standard formulation, but accidental ingestion should be followed by rinsing or medical advice.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Furniture finish or coating compatibility
No recalls or widespread reports document damage to varnishes, lacquers, or upholstery from WD-40 spray. However, applied to unfinished wood or delicate fabrics, the oil may leave stains or discoloration; test on an inconspicuous area first.
The full breakdown
The brand's record and disclosure
WD-40 Company publishes Safety Data Sheets (SDS) for its products, listing mineral oil and petroleum distillates as the active ingredients. The company does not highlight PFAS use in public statements, and no major recalls or regulatory actions specifically targeting this product for chemical hazards have been issued in the United States. The product has been in continuous consumer use since 1953 without documented mass health complaints tied to typical lubricant exposure.
How it compares in its category
As a lubricant sprayed onto furniture hinges, drawer slides, or locks rather than a furniture finish or cushion material, WD-40 is outside the typical hazard profile of furniture coatings or foams. It poses lower off-gassing and chemical leaching risk than furniture-specific products like flame-retardant upholstery treatments or polyurethane finishes. The aerosol format carries standard inhalation and accidental exposure risks common to spray products, but not furniture-specific coating degradation hazards.
If you buy it
Use only in well-ventilated spaces to minimize inhalation of propellant vapors; do not spray directly on upholstery or skin. Apply sparingly to metal hinges, springs, or mechanisms and allow solvents to evaporate before contact with textiles or food-contact surfaces. Store in a cool, dry place away from heat and ignition sources. Check the flexible straw for cracks or leaks before each use, as propellant escape poses both inhalation and flammability risks.
