If those of you who choose not to use Woolite, but use a "Leather Cleaner" what to you think is in it? It's still a mixture of water, soap, coloring, fragance, and other agents.
Bottom line, you're still cleaning with a "soap" type detergent. And, most leather cleaners do not instruct rinsing afterwards.
But those that do rinse, you're doing the correct way in making sure all cleaner is off the leather. Best way to judge is with 100% white cotton towels to inspect how much dirt or cleaner is left. It also aids in drying the leather as well.
Bottom line, you want to get whatever you used off the leather along with any dirt to better protect the skin.
You want to be absolutly sure the leather and whatever is below it is dry before any treatment. And with todays leather, go very lightly. Only the areas where there is quite a bit of wear will absorb more conditioner seeing that the protection that was once on the leather has now worn off.
LM products work very well and can maintain leather in the best shape possible. Use it sparingly and follow the directions carefully. Do not over-apply any conditioner no matter which brand it is. Treat the leather as if you were applying a sealant, less is better.
As for other leather products that once were used in tack rooms, it became a marketing idea that they can use it on automotive leathers. They have reformulated it, but it still remains as a tack room leather cleaner/conditioner for unprotected leathers. Some swear by it, but that's due to treatment of older leathers that had no protection.
Always use a leather product for it's intention. Automotive cleaner/protectants for the car and keep the others for home use only.
So far, I've used LM, Zaino, Sonus, 1Z all with very good results and for different reasons. Zaino has a very distinct leather aroma. Sonus does not, but draws it's smell from the liquor used in tanning of the leather. 1Z has a more mild leather aroma and a more creamy format to it.
As long as you get all the dirt, oils, sweat etc off leather, you'll be presearving it longer!
