Why Use TRG Universal Cleaner? TRG Universal Cleaner can be used to clean your favorite leather and textile shoes, goods and upholstery. Simply shake the bottle and apply the product to heavily stained parts. We recommend the product, like all our products we advise first testing on the leather on an inconspicuous area of the item. What does TRG Universal Cleaner Do? This leather cleaner is especially formulated to be used prior to TRG Leather Renovating Balm as it not only cleans, but opens the pores of the leather, allowing it to accept the colour and feeder. As such, when using prior the the restorer, you should apply to the entire item, not just stained areas. We do recommend the entire item is cleaned prior to use of any of our products, as grease will prevent the proper bonding process. Can I Use TRG Universal Cleaner On Anything Else? Yes, in fact it's very versatile. One of our customers made a special mention that it worked great on his classic Escort metallic paint work to remove grease without any damage at all to the paint.
