RE: Newbie to Z3's and cleaning properly

Dear all,

I recently purchased a 99 2.0 Z3 for my better half. We were looking for something cheap to run and after looking and hating everything I asked what she wanted and she said a Z3 as she always wanted one.

Last weekend I washed and polished it with autoglym products and I overheard someone at the gym on about claying. he same person is lending me a full detailing kit by Maguiers.

Do I need to use a detergent that will take the polish off the paint that I applied last weekend to get the benefit of the clay removing the dirt from the actual paint underneath? Or do I just wash it with the shampoo meant to preserve finishes and clay the polish.

If I need to remove the polish can someone recommend a dedicated shampoo please.

Great forum by the way, I gleaned lots of knowledge about buying a Z3 from here leading to an informed and v happy purchase. My GF has told her freinds that she thinks I love the car more than her since we bought it! :o

Thanks in advance

Claying will remove any surface contaminants including polish so just wash then clay, polish and wax in that order. If you use a durable wax such as Collinite 476 or Meguiars 3 stage wax you'll find you won't have to re-clay or polish the paintwork for several months, and you can use a lightly concentrated shampoo/water mix to remove grime that builds up on the wax without removing the wax layer itself.

Welcome to the forum. :)

I would wash with a very diluted "fariy liquid" to strip the wax (this is the only time you should ever use a household detergent on car as it contains soooo much salt :wink:), clay and then rewax (you don't need to polish unless you want/need to remove some swirls so for a first go I would skip this step).

You need to use a lubricant with the clay so make sure you get that as well :wink:

Thanks for the tips people. As I thought Jonttt, I need to remove the Autoglym SRP first otherwise my clay will get full of the poish/wax before I got down to the contaminants.

I have read many websites and all guides seem to assume there is no wax or polish on already.

I think I'll wash it with a light solution of fairly liquid to remove the wax and rinse thoroughly, then wash it with a decent maquiers cleaner to prepare the surface and remove any residue, clay it, polish out any imperfections then apply a protective layer of wax.

I've been givven a bag full of meguiers car detailing stuff. Though the car shampoo seems to prtotect layers of wax etc, hence my question.
