This tub of superb Fiebings saddle soap is ideal for cleaning very dirty leather. I use it myself on repair work and find it excellent.
All that is needed to apply this saddle soap is a dampened cloth or sponge. It works well on saddles, shoes, luggage, belts, holsters, handbags, sports gear and leather furniture. It is not suitable for suede, nubuck or 'rough-out' leathers.
Whilst saddle soap will clean leather thoroughly and restores some of the natural leather oils, very old or dry leather may need an extra conditioner to restore suppleness and flexibility.
Please don't eat the stuff, you will be sick. Yes, very sick indeed and it tastes disgusting and no, I'm not telling you how I know this...
