Non-Acid Wheel Tire Cleaner

The D143 represents Meguiar's most aggressive wheel cleaning chemistry, designed for professional detailers dealing with severely neglected wheels. With a pH of 14.5-15.5, this product approaches the theoretical limits of the pH scale - essentially a concentrated sodium metasilicate solution with surfactant and chelation support. The formulation is nearly identical to the consumer Hot Rims G95 but with higher caustic loading, achieving an additional full pH point. The dark red color serves as a visual indicator to differentiate from milder products and signal the need for caution. The 'Non-Acid' name is technically accurate but potentially misleading - this is the most caustic product in the database, not a mild alternative.

Key Differentiators

• •HIGHEST pH in entire database (14.5-15.5) - approaching theoretical maximum
• •Professional 'Detailer' line (D-prefix) vs consumer line
• •Dark red color as visual hazard indicator
• •Higher caustic loading than consumer Hot Rims G95
• •Multi-surface: wheels AND tires

Potential Concerns

• ⚠STOT RE Category 1 - causes permanent respiratory damage with repeated exposure
• ⚠pH 14.5-15.5 is EXTREMELY caustic - immediate chemical burns possible
• ⚠Eye Damage Category 1 - can cause permanent blindness
• ⚠NOT safe for any sensitive wheel finishes - will attack clear coats, anodizing, polished surfaces
• ⚠Metal corrosive - generates hydrogen gas with aluminum/zinc contact (explosion risk)
• ⚠Requires corrosive-resistant storage container
• ⚠'Non-Acid' name may mislead users into thinking it's gentle - it's the opposite
• ⚠Must keep away from reactive metals to prevent hydrogen gas generation

MOST EXTREME pH in database. Professional-grade product requires full PPE. Repeated inhalation exposure causes respiratory damage. Keep away from reactive metals (aluminum, zinc) to avoid hydrogen gas generation.
