Okay -- to the questions. FYI, the articles appearing on our website were all published throughout the equestrian industry at some point -- and, so as not to toot our own horn about Leather Therapy -- we spoke in generalities, just to educate.
You'll find that Leather Therapy products are very versatile, and intuitive -- once I explain them to you.
WASH - enables you to clean dirt, debris, and even heavy grime from leather reins, bits, etc. Use this before you use Leather Therapy Restorer/Conditioner. For really heavy soils, just spray it on and leave it for approx. 15 seconds. This is a highly concentrated surfactant, so you won't need much. You can use a sponge or damp terry cloth for regular quick wipe-downs after riding. It's not necessary to rinse this product out -- it's full of leather enriching emollients. This is the maintenance product of the group.
Note that all of our products are water-based and easily rinse out of sponges, cloths. Or, if you used too much of Wash or Restorer, simply wipe down the leather with a damp terry cloth to remove excess product.
RESTORER / CONDITIONER is the work horse of the group. You don't need to use this product frequently. The feel of your leather can tell you if it's interior fibrils need lubrication. Or, if your leather is subject to mold problems, this is the product that can fix it. If the leather looks dry (faded) or feels kind of stiff to the touch, then it certainly can use a coat or two of Restorer.
Keep in mind that some leathers will hold lubrication longer than others. (Leather was,of course, living skin, and is subject to the same variations and qualities). It's really an interesting science.
FINISH is a wonderful topical product that is used to impart a protective luster to leather. On reins, it forms a light barrier to heavier soils. From bridles to shoes, it adds a light second skin to leather. It also tends to blend in and"finish" leathers that are spotted, etc. Used also on purses, soft sided luggage, etc. It is not a true water repellant, but serves as a light protective barrier to light moisture and dust. Only necessary if you want a more satin-like finish to show off your leather and a silkier feel to your reins - or leather clothing. Optional product which should be used on dry -- not freshly conditioned leather.
WATER REPELLANT is great for suede, nubuck, rough out leathers or when preparing leather for a rain soaker. It is not used on a regular basis. It's an optional "add on" product to the line and can be used on an "as needed" basis. This product CAN ONLY BE APPLIED TO VERY DRY LEATHER.
Thanks for asking. Hope I've answered your questions clearly. Anna
