First of all when waxing you want to mask off those parts. I know most of us don't but it's a sure way of protecting those parts. Wax and plastic don't mix. The Mother's back to black does a good job but like someone else said you'll be re-applying it. It's more of a cover up product than a cleaner. Not to mention if it rains it will run down your doors and leave a nice drippy mess. I used it on my 2000 mustang on the plastic mirror housing and it made it look great but as soon as it rained it just ran down the doors and made a mess. It would be good for something like a black chin spoiler. I'm sure their is a good automotive plastic cleaner for things like this.

I use the Turtle Wax Ice on my mustang for precisely this reason. Lot of plastic on our cars and this product really works incredibly on my car.

I've seen a drop of motor oil on a rag used to polish the wax off.

You dash is already cracking? You need one of those dash mats to keep the sun damage at bay.

Oops, my bad...thought it was a Meguiars thingy (back to black)

I usually use "Trim Shine" made by Stoner to clean or brighten up the black plastic on my car. I also use "Invisible Glass", also made by Stoner. I was told about both by a local shop that does a lot of detailing. They also said to use lemon pledge on the dash and door panels instead of Armorall, so that there isn't a greasy buildup on the glass from product being exposed to heat. I like to use leather wipes made by "Weinman" company, they are meant for topgrain leather furniture, but says it's suitable for automotive interiors, and so far it's worked awesome.

Mequiars has a product of vinyl and rubber. I've been using if or a long, long time. The rubber vinyl parts on my 27 year old car still look and feel just like new. Not only does it take off the white, but, it makes vinyl rubber look and feel just like new without any phony shine or sticky residue.

I use eagleone nano wax it's a clear liquid and does not leave any white goes on very nice and even comes off nice and looks great. The Turtle Wax Ice is a polish not a wax job and it does work great on plastic and inbetween washes and used with a Duster works great.

You can also use Kerosene (Fuel Oil). It won't hurt the paint and is great for removing tar. I've been using this cheap alternative cleaner for years to remove wax residue from textured black plastic and matt black painted surfaces. I then use a protectant as a follow up.
