OK let's talk a bit about the cleaning products that you use for your Outlander.

For the dashboard, door panels and the overall interior plastic surface of the car so far I've been using Armor all which is a great cleaning product but unfortunately it leaves some kind of "water marks" on the plastic surface which you can see when the sun hits it. Therefore I'm looking to replace that with something else. What do you guys use?

For the glass I've been using for years this spay called Invisible glass and it is amazing.

For the leather I haven't found anything yet which I feel safe using so any suggestion would be appreciated. I got these wipes from Meguiar's (same format as Armor all) and I used it at the back of the seat just to see how it works. The leather became so glossy and darker than the rest of the surface and it stayed like that for probably 2 weeks and now it's gone. To be honest the difference was so noticeable that I got scared for a second.lol
Any suggestion for cleaning the leather?

 

I use Meguiar's Natural Shine on dash and doors. It gives a deep rich look without being overly shiny or greasy.

I have cloth seats that I vacuum weekly, then use a clean damp wash cloth to lightly wipe them down. I also use the wash cloth on the leather steering wheel to keep it clean.

On the exterior I use Meguiar's Car Wash and wax it with Meguiar's NXT 2.0

 

Armorall is NOT a great product.

For leather - use Zaino Leather in the Bottle or Lexol. Or Meguiar's Gold Class spray. Or Leatherique.
Or Adams Leather conditioner

The dash is plastic, so no need to use anything special. Just a Swiffer duster works great to remove dust.
But if you really want to spray something there - use 303 Aerospace protectant.

For Windows - Stoner Invisible Glass and a piece of newspaper. Actually there is a better, cheaper alternative spray, that works even better, but I won't tell you what it is because you will all go buy it and cause prices to go up
