There have been rare cases where certain spots on say a BMW 'armrest' have been removed by leatherique. But 99.9% of the time it is safe.
The leatherique isn't the problem here,.. it is the armrest in this case. It is faulty in some manner. Dye not properly applied, mixing of chemicals, who knows.
I've tried a TON of products on many cars,.. Leatherique, while pricey, and somewhat odd in that you clean after you condition,.. works, hands down, the best.
This is my tip(s).
Clean the leather before you apply any of the leatherique products. Use a woolight dillution, or simply soap and water,.. or just water and a rag. Get any thick residue off the seats, any oils off the seats/armrest etc.
Let that dry/wipe dry.
Then -- Apply the Leatherique Oil. Apply it with an applicator, (on the applicator) do not spray is or squeeze it out on the leather. You don'to want concentrated areas of it.. you want even layers.
Once you get the oil spread over all the leather to your satisfaction -- (Don't use MORE in hopes of better absorption, just use a little bit). Turn your heat on 80 Degree's.. and close the car. Leave it for 30minutes or so.
Open it up, turn off the heat.. and wipe the oil off with a dry Microfiber.
Then apply the Cleaner with a different applicator, evenly. Use the brush over all the seats, don't scrub as hard as you can.. but a little scrubbing isn't going to hurt. This loosens the oils, and dirts pulled up from the previous application and the cleaner. Wipe this dry.
Check it out, if it looks good, your done. If not, repeat from the start again.. (remember you are using a LITTLE amount/small amount.. So repeat application isn't a problem).
Also, don't go putting on the leatherique oil.. then putting on saran wrap over it (like I've heard people doing) for days on end. This is silly, inpractical and does no good. It wasn't designed to sit like that. Also don't let it sit all day long on the seats,.. 30minute is more than enough time for absorption.
You see, the key , imho, is regular application. You can't always get things 'perfect' or where you want them in one quick blow. If you apply it and it is better but not 'perfect'. Don't worry -- Wait a day, or a week. Redo it. Keep on doing it every week for a month, or two. It will get better every week.
Then once at a level of your acceptance, maintain it by at least monthly application.
Leatherique is expensive stuff. More is not better,.. It does absorb unlike some claim it doesn't -- But it isn't going in like a sponge on many leathers. It takes heat and *some* time , but not an extravangent amount of time. Given this smaller amounts, applied more frequently, again, produce better overall results.
If you have any problems with dye removal and so on, or discoloration it is due to inproper application, which falls into using too much product, scrubbing too hard, leaving it on too long, and so forth. -- It is also due, more often imo, to a problem from the factory. As some people will have certain small sections of a leather console in their car seemingly get destroyed (dye wipes off) while the rest of the car does wonderful. Is that the leatherique? No, use logic. It is a console that is improperly protected.. (I am no expert on dyeing and leathering vehicles, but I know a specific problem when I see it). If it damaged all the leather in an equal fashion, sure its the product --
I can see some leather not withstanding some products, it happens.
Which is why with any cleaner/conditioner product they say test on an inconspicous spot before applying elsewhere. With all the various kinds of cars, leathers, seals, processes it is impossible to predict and test them all. But for the majority things are fine.
I know that is redundant,.. but I have been reading some horror stories on leatherique and the people are blaming the product when that is just rediculous. I can understand their frustration, and the conclusion, but from an outsiders point of view it is just a wrong conclusion.
Given all of that -- There are still wonderful leather cleaners, and conditioners that aren't as expensive as leatherique -- Leatherique is about the most expensive on the market.. of course not quite, but in the top 3-5 easily. It is for the name, and the quality. Obviously it doesn't cost 45-50$ to make two bottles.
I've tried probably 15 different cleaners, and 2 dozen conditioners over my lifetime.. and have never turned back from switching to leatherique. Lexol was my choice years ago,.. but , obviously, that has changed
The main thing you want in the sun is protection -- So at least protect it. If you have some Aero 303 -- Use it on the leather! It is fine, it won't condition it, but it will protect it.
It even isn't a bad idea to put a light coat on over the leatherique process if you'd like a little more UV protection. Just depends on the conditions your car is commonly exposed to.
Lastly,.. everyone has their favorites and thats great! I was recommended Lexol by a professional in the leather industry -- He knows his stuff, but he doesn't know it all, nor do I. Just speak from experience. What I use is quite good enough for me, and if there is better I will eventually find it.
To releather a car it is still $1500 or so, .. it isn't as much as many people think.
*This is top quality leather, installed.. locally* -- You can get estimates for thousands from some places.. I have checked years back.
