2022-2024 Nissan Window Glass Foreign Material Removal TSB

Nissan Technical Service Bulletin (TSB) NTB13-0281 addresses the issue of Nissan window glass foreign material and provides a recommended cleaning procedure. This bulletin, last updated on April 29, 2024, offers a method for removing various types of foreign material from the surface of window glass using a specific grade of steel wool.

Symptoms

Owners may notice various types of "foreign material" on the surface of their vehicle's window glass. This material can obscure visibility and may not be easily removed with standard cleaning methods.

What Nissan Owners Should Know

This TSB highlights several critical points for owners and technicians regarding the removal of Nissan window glass foreign material:

• Not a Warrantable Condition: Nissan states that "Foreign material on the window glass surface is not a warrantable condition." This means the cost of cleaning or related materials will not be covered under warranty.
• Shop Supply: Materials used for cleaning, such as the recommended steel wool, are considered a shop supply.
• Professional Guidance: Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers.' While the procedure is straightforward, it emphasizes the need for proper technique to avoid damage.

Important Warnings

To prevent damage to your vehicle's window glass, Nissan provides the following strict warnings:

• "Do not use dirty or contaminated steel wool. Dirty or contaminated steel wool will scratch the window glass. If the steel wool is dropped on the floor, get a new piece of steel wool to clean the window glass."
• "Do not use power tools" when rubbing the window glass with steel wool.
• "Do not use any cleaners with the steel wool."
• Always use "new steel wool from an un-opened bag" to ensure it is clean and uncontaminated.
• Store any unused portion of steel wool in a re-sealable container to prevent contamination.
• "Always try to clean any window glass surface issue first with #0000 grade super fine steel wool before glass replacement is considered." This suggests that many issues can be resolved with this cleaning method, potentially saving the cost of glass replacement.

Recommended Cleaning Procedure

If you are experiencing Nissan window glass foreign material, the TSB outlines a specific cleaning process:

1. Initial Cleaning: First, clean the window glass with soap and water. This step is crucial to remove any abrasive dirt or grit that could scratch the glass when using steel wool. Ensure the glass is thoroughly dried after this initial wash.
2. Steel Wool Application: Use #0000 super fine steel wool. This particular grade is widely available in most hardware stores.
3. Manual Rubbing: Gently rub the window glass surface manually with the steel wool. The TSB emphasizes that in most cases, the window glass cannot be damaged by manually rubbing too hard or too much. However, power tools should never be used.

Required Materials

For this cleaning procedure, the primary material required is:

• #0000 super fine steel wool: This specific grade is essential for effective and safe cleaning without scratching the glass. It should be new and from an unopened package.
