Mckee’s 37 – SiO2 Leather Guard

Advanced Ceramic Protection for Leather

Experience next-generation leather protection with McKee’s 37 SiO₂ Leather Guard, featuring an advanced SiO₂ blend designed to improve surface adhesion, reduce surface drag and deliver a noticeably drier tactile finish.

Unlike traditional leather conditioners and protectants, SiO₂ Leather Guard forms a durable, crystal-clear protective coating over leather surfaces. It helps protect against abrasion, UV exposure, dye transfer, food spills, sunscreen, grease and everyday grime, while maintaining a clean, OEM-style matte finish.

Designed for long-lasting protection, this high-performance coating requires application only twice a year, making it an ideal choice for daily drivers and vehicles that demand reliable interior protection.

Suitable for smooth and perforated leather, vegan leather, vinyl and rubber surfaces, SiO₂ Leather Guard helps preserve the appearance and feel of your interior while making routine cleaning easier.

McKee’s 37 SiO₂ Leather Guard is a specialised protective coating rather than a traditional leather conditioner. Its advanced formula creates a durable protective layer that helps shield leather upholstery from dye transfer, abrasion, spills, sunscreen and oily grime.

When properly protected, everyday dirt can be removed more easily with a damp microfibre towel, helping maintain a cleaner interior.

How to use

• Thoroughly clean leather using McKee’s 37 Total Interior Cleaner
• Apply SiO2 Leather Guard directly onto a TRC Black Microfiber Terry Detailing Sponge Applicator
• Work SiO2 Leather Guard into the surface using a circular, overlapping motion
• Apply more as needed
