There’s so much information available online when we’re shopping now, that it’s easy to find lots of detail about products like Grangers G-Wax. This is of course really helpful, but there’s almost too much information available, so it’s important to know exactly what you’re looking for.

Here at Grangers, we’re big animal lovers so we have never tested on animals and all of our products have and always will be cruelty-free.Our Head Office is located in Derbyshire, England. We love living in the heart of Derbyshire and getting outside into the Peak District. Howie, B.N., Donnelly, P. & Marchini, J. A flexible and accurate genotype imputation method for the next generation of genome-wide association studies. PLoS Genet. 5, e1000529 (2009). The waterproofing product is added after cleaning to seal the boots for water repellent protection. The best product for waterproofing leather boots should offer effective water repellent sealing. However, it should still be able to promote adequate breathability. After applying the waterproofing product, the last step is to condition the boots with the leather boot conditioner.

Of those waxes mentioned so far the Meindl Sport Wax is by far the softest but it does take some time to work it down into the leather. If you don't take this time you will end up with a pair of super powerful dust magnets as I found to my cost. It might be helpful if you stated what make and model the boots are. As I've stated before there are different qualities of leather and some manufacturers even apply coatings which artificially waterproof the leather but this coating can also prevent normal waxes/oils penetrating down into the leather. No: It applies to waterproofness, windproofness and breathability for the useful life of the product"Finucane, H. K. et al.

That got us thinking though, that we’re looking at every possible item from Grangers so it would be good to narrow our search down even further and only look at Grangers branded products within the Cleaning & Proofing category.
