Why Use Suede Soft Cleaner 4.0?

- Handling soil
- Light food contamination

Suede's protein fiber structure is sensitive to harsh cleaning systems.
Suede 4.0 is formulated to clean while helping preserve:
- Fiber integrity
- Color stability

3. Lifts and Suspends Contamination
Rather than forcing soil deeper into the structure, Suede 4.0 helps suspend contaminants for easier removal during the rinsing stage.
4. Prepares for Rinse 3.0
Cleaning and rinsing perform different functions.
- Suede 4.0 lifts and suspends contamination.
- Rinse 3.0 flushes out the resulting residues.
Together they create a cleaner foundation for restoration.
