Review on GYEON Quartz Q²M LeatherCleaner Strong 500 ml - Effective and Gentle Leather Cleaner for All Leather Types - Eliminate Dirt and Oil, Ideal for Leather Protection by Nestor Orbita

This product is really good at removing dirt from leather. The most important thing I learned while cleaning was to read the instructions. You may need to add a mixture of water to reduce cleaning power. Make sure you test it on a less obvious spot first to see if you need to add water as a dilution.
