I bought these Greb Combat boots at the local surplus. They are almost new, they have never been polished and are not broken in and I paid them only $45. But they are dirty and that's the reason for the low price. They have probably been worn during a bootcamp or something. I removed most of the dirt on the soles with water, a bit of Palmolive and a plastic brush.

Now for the leather, what is the proper way to wash them, and then condition and wax them to protect against salty slush, oil and water?

I've read that using regular soap is bad for the leather because it's alkaline. What is the best strategy for taking care of them boots? I was thinking to use Lexol-pH cleaner then Lexol conditioner and then somewhat waterproofing them with wax (less breathable result) or silicone (more breathable) or something but it's not clear...

Any advice welcome

Thanks
