Leather does not need 'conditioning'. The only conditioner leather needs is moisture so you need to use a water based cleaner and protector and this will keep your leather in good 'condition'.
TO FEED OR PROTECT
There is still a huge body of detailers out there (and a good percentage of upholstery cleaners/leather technicians/retailers/consumers) who are desperate to ‘feed’ and/or ‘condition’ their leather. Usually this would consist of spreading some sort of oil or grease containing product onto their leather (milk, Vaseline, baby oil, musk oil being some of the more bizarre we have come across!!!!).
What we ask is why?
When leather is manufactured a certain amount of oil and fat is introduced into the hide and, (with the exception of one or two complex situations) this is where it stays. It does not evaporate or migrate or leave the leather by any other means.
What does leave the leather is moisture (water), and it is this that needs replacing.
Dry leather is more susceptible to a whole range of problems. The most obvious is cracking, both of finish and fibres.
Next is raised absorbency levels which means body oils containing fats and acids will more readily soak into the leather (ever seen those dark areas on head rests and arm ends on furniture) eventually destroying finishes and the leather itself.
Dry leather will be a sponge for spills, tea, coffee, red wine, ink, any product with colouring once soaked inside leather will leave a permanent stain, which depending on leather type may or may not be fixable�at a price.
Some hide foods and conditioners if properly formulated and used correctly with leather type taken into account will not damage the leather, others particularly if they contain waxes and silicones are likely to do more harm than good. The basis of a good type would be an emulsion of lanoline and water. The water re-hydrates and the lanoline helps the leather to hold the moisture for a little longer. This does not , however address the issue of protecting the leather. But it is cheap to manufacture and therefore can be sold at a low price (or an expensive price if it has a 'name' attached to it!!).
Leather Protectors on the other hand are a complex formulation and the ingredients are expensive, therefore the end product is more costly, often 2-3 times the price of a conditioner. BUT THEY DO WORK.. We always use the ‘Scotchgard’ analogy to explain how, without getting technical it is the easiest way. Its effectiveness can also be demonstrated. Leather Protector performs all the good functions of a ‘conditioner’ or ‘food’ product but will leave a virtually invisible, breathable, non greasy coating on the surface. This will be effective at helping to resist stains via spillages, dye transfer and day to day soiling, including body oils… It is not bullet proof and the leather still needs cleaning, but the dirt will be sitting in or on the protector and will clean off more effectively. During the cleaning process the protective element will also be reduced and need replacing. Good Protectors also contain UV protection which will help against fading etc. in sunnier climes.
How often is the next question and a tricky one to answer. Some leathers we would recommend a light clean and protect once a month, others a good clean and protect 1-2 times per year. There are so many finishes on the market at present that it is not wise to generalize. Experience and knowledge is the best guide. However on most car leathers 1-2 times per year should suffice.
Bottom line– to treat furniture with a good quality Leather Protector will probably cost a little more per average car than a ‘conditioner’ or ‘food’ product but the benefits far out way this cost and the effects can be demonstrated for your customer to see.

The question of smell is a tricky one. The smell comes from the chemicals used in the tanning process and not from the leather therefore the range of smells is enormous and each car may have a different one depending on where the leather was produced. Replicating this smell has been a frustrating excercise for many a car manufacturer. From experience we have found that most products do not 'smell' as your custmer would understand the 'leather smell' to be and any smell does not last long. It is far better to use a seperate 'leather aroma' after you have finished your work. This will last much longer.
Hope this helps
