I used 303 on my interior leather today. I suspect there may be debate on whether or not to do this, but it sure looks good. The seats now seem a little slippery. My black interior has been a bit faded. The dealer I bought my car from over a year ago seemed to enjoy letting it bake in the Florida sun all day with the top down. Car people can be pretty dumb on things like that. I have tried real leather cleaners and such, but nothing brought back the shine like 303 did today. It will be hard not to continue using it unless I learn that this is damaging in some way. The back of the 303 bottle does say it is ok for leather.

I personally wouldn't use it on leather. I'd use a dedicated leather conditioner. It's great on vinyl, that's for sure. Leather? ehh... it's basically a silicone spray and leather really benefits from natural oils and such that leather needs to stay strong.

Basic rule of thumb - use a leather cleaner or protectant on leather OR vinyl, but don't use a vinyl cleaner or protectant on leather.

animeS2K, I see you have learned very well.

I would not use 303 on any leather, it may even soften up the finish and cause premature wear due to its chemical components. Get it off with a proper leather cleaner and then condition with a proper conditioner.

I wouldn't use 303 on leather either but it is not a silicone spray. You wouldn't want to use silicone on vinyl or plastic.

From the 303 website:
303 contains no petrochemicals, silicone oils or petroleum distillates.
