Leather Restoration Co's moisturiser instantly softens leather that is dry and stiff. It has a very low evaporation rate and the area moisturised can be refinished with no adhesion issues. Applying  moisturiser on the flesh side of the hide gets immediate results and the use of warmth, scrubbers and scrunching the leather aids in driving this moisturiser into the more compact fibre bundles on the top grain side of the hide. It will be effective where it can get through microfractures in older leather finishes and topcoats.
