THIS is how you wash a Porsche!

To understand the full thing, start the thread at post #2. More detailing in there.

The answer is to take your Macan directly to a Professional Detailer.

Have them wash, clay and prep the paintwork prior to them applying a coat of Gtechniq Crystal Serum Black topped off with a coat of EXO.

They can also prep the wheels and apply a coating of Gtechniq Wheel Armour.

When finished your Macan will have sealant coatings that do not need waxing ever.

As for look, it will be stunning with a mirror quality of finish.

A quick wash will mostly remove dirt and grime, spray with fall out remover, then snow foam, lance wash off everywhere and rinse with water that has been through a softener/filter and you are good to go, no need to dry as this quick wash is no contact.

When required a standard two bucket wash will restore the finish.

Quick wash on my Macan 20 minutes including 2 off 5 minute dwell times for the fall out remover and snow foam. Thorough wash 2 hours.

A more detailed response is the system I suggest, it has worked well for me here is the text I post on a few forums.
.
.
There have been quite a few seperate posts asking the same question, should I get my car detailed?

It all depends on how fussy/OCD you are about your Macan, so if your are not bothered move on to another thread, if you are fussy/OCD read on.

OPC offer of Swissvax, Lifeshine or other wax based product
An offer by the SE at your OPC will and there is no doubt about it offer a treatment like Swissvax, Autoglym Lifeshine or a Gtechniq Light which would be a wash, dry and apply the sealant and buff it up when cured. The car will look excellent but they will not undertake correction to paintwork and they will only wash, dry and apply the treatment which will take 4 hours labour (£60) and a probable £20 in materials yet they will charge you between £300 and £600+VAT.

Wax based products
Waxing a car provides a sacrificial layer on top of the paintwork, as the car is washed this layer wll gradualy reduce until a reapplication is required. There is no doubt that wax based products give a superb finish, they are however labour intensive to maintain the finish. The cleaning technique will be similar to that described below and the equipment needed the same.

If professionally applied the paintwork cleaning technique will involve a Claying process to thoroughly remove surface contaminants. Then paint correction may be undertaken however this will be depending upon cost. Once the wax is applied the Claying and correction process will then only be required occasionally to essentially retreat the car. I have seen on other sites that Carnuba wax is a highly used product for a concours finish.

Pro Detailing
To get the best paint finish on your Macan I suggest that you consider getting it Professionally Detailed, and not a treatment offered by your OPC, discuss your requirements with the Pro Detailer and they will recommend a product like Gtechniq, which is a sealant and not a wax product. Depending upon the finish chosen the guarantee on these treatments can be up to 7 years.

The Pro Detailer will also recommend how they would like to receive the Macan, probably unwashed and direct from your pickup.

A Professional Car Detailer will follow a process something like:-

Wash and dry the car
Clay the car
Paint correct, note that this is the labour intensive element
Apply Gtechniq Crystal serum
Apply Gtechniq EXO top coat
Clean and apply G4,G6 and G1 treatment to glasswork
Remove wheels
Wash and dry them
Correct finish
Apply Gtechniq wheel armour
Let all coats cure for at least 24 hours
Refit wheels
Collection

Note that this is just the exterior there is also the interior and glass that can be protected

Now if you go to the Gtechniq website you can build up your own cost for the work you want doing and then use this figure to negotiate a fixed price from your chosen detailer, they may want to see the car first to access the amount of pain correction they need to do.

My Pro Detailer had my car for three full days and it took all of day 1 to wash, dry, clay and paint correct my Macan. Day 2 was applying the sealants and doing the wheels. Day three the car just stood there curing and They put the wheels back on first thing on day 4 when I collected it at 09:30.

Paintwork correction
A new paint finish will have an irregualr surface and light swirls and very fine scratches. These may be difficult to see but they will probably be there on all new cars. The paint correction process involves decontaminating the car via washing and claying (Youtube ...... claying ...... to see the process) and then with the aide of a task specific polishing machine cutting and polishing compounds are used to buff the paintwork to a mirror finish. This element will account for the Lions share of the labour costs associated with the treatment.

Equipment and products suggested to maintain the finish (applicable to wax and sealant coatings)
The kit you will need:-

- Power washer, a Nilfisk 150 is the recommended unit
- Snow foam lance, compatable with the fittings on your powerwasher
- Two Fleece wash mitts (one long fleece for upper and one short fleece for lower body panels)
- A set of "Wheel Woolies" wheel brishes, Google the name to find suppliers
- A microfibre wash mitt specifically for the wheels
- Drying towels (no chamois is allowed near your car), do buy good quality ones with Waffle Weave for best drying. I can recommend Meguirar's Water Magnet Drying Cloths, at least 2 of them
- Cleaning microfibre cloths (for glass and internals), do take note that not all microfibre cloths work effectively. - 0ppm water softener/filter (Raceglaze or Aqua Gleam or similar) plumbed into your water supply if possible
- A TDS water test meter will show the effectiveness of the water softener/filter by giving a readout of the ppm as it leaves the unit, Kasfranks99 writes in a later post that he using a TDS-3 which will cost around £15-£20.
+
- Sealant maintenance products
- Snow Foam or/and Citric Wash, recommended products are Valet Pro PH Neutral and Ultimate Finish Snow Foam

Washing your car
QUICK WASH
Spray fall out remover on car
Leave 5 minutes
Power wash off
Spray snow foam onto car
Leave up to 10 minutes
Power wash off
Hose off all car with the softened filtered water nb this step is vitally important to avoid water spots.
Put kit away and brew up

The process below uses the two bucket cleaning method, and requires that at the first sign of debris suspended in the wash and/or rinse water the buckets are emptied and refilled.

THOROUGH WASH
Spray snow foam onto car wheels
Leave 10 minutes
Power wash off
Two buckets, one with just water (Rinse) and one with the shampoo (Wash) that is mixed in the correct ratio to water
Using wheel woollies clean each wheel, once in contact with a wheel the wheel woolie is rinsed and shaken before it goes back into the shampoo bucket for the next bit of cleaning
Once each wheel is clean hose it off with the softened/filtered water before moving on to the next wheel
Wheels done for now
Spray snow foam onto car body
Leave 10 minutes
Power wash off
If there is still visible dirt residue repeat three prior processes
Clean out bucket and refil with fresh water and shampoo
Using a wash mitt clean bodywork from top down only working in straight lines, but once the mitt has been on the body it goes into the Rinse bucket and given a shake, then shake it again out of the Rinse bucket and put it in the Wash bucket, (the one with the shampoo)
Repeat this until the whole car is clean, using the second wash mitt on all body panels below the sideblades.
Hose off car including the wheels with the softened/filtered water, this will limit water spot formation in locations that are difficult to dry.
Towel dry by patting.
You can then apply a Quick Detailing spray and lightly dry the surface to maintain the sealant product.
Stand back and admire your labours

General Notes
A domestic power washer is not likely going to achieve a thick foam, the foam applied by these models may function OK and as a consequence a second application may be necessary.

Water filters/softeners are useful and if you are sparing in the use of the water they should last a reasonable amount of time. These units undertake a chemical Ion Exchange process between the water and resin. With usage the resin becomes less effective and requires replacement or replenishment, as the resin is quite dense it will also act as a filer to remove the debris that is present within the water supply. I have costed both the Raceglaze and Aqua Glram units and for my useage and location the Aqua Gleam is more economical but only just, in a harder water area and the economica spin around to the Race Glaze unit.

I suggest that you only use the filtered/softened water to rinse off the car, using it via the power washer will considerably reduce
the life of the filter material.

Do take note regularly of the colour of the water in the buckets and change it at the first sign of any quantity of dirt in the water, especially change the rinse water 2 or 3 times during the washing process.

A "Thorough Wash" on my Macan takes about an hour and a half but I do a "Quick Wash" weekly or if it looks grubby or has bird droppings it on it.

The kit needed may seem excessive but the water from the softener/filter will stop water spots forming on the paintwork, the sealant coating will enable a quick wash with no drying being required.

This is not a definitive method but a process that works for me.

Also read up on the washing process related to the product applied to your car so you can follow the manufacturers recommendations.

Join the "detailing world" forum where more definitive advice can be found.

HARD WATER AREAS
If you live in a hard water location then a professionally installed system with a brine backflush may well be more economical over the course of a few years and you would have the benefit of softened water in the household. and softened/filtered water for all car washing. The only costs involved in these pro units are for bags of salt and an occasional resin change. I have installed quite a few of these within industrial situations where the water is intended to be used in steam boilers and as you can image hard water scale and a steam boiler are not ideal companions.

Wow, before reading that I thought I had adequate car washing skills. I'd better get with the program and relearn my washing technique, seems I am missing a few steps, make that many steps!
@TheBrit: If your ever in the States drop over and show me how to do all this? I'll have a cooler full of beer and other thirst quenching refreshments!

That is the best and quickest way to wash the exterior of the car. Touchless method. Safest way as well. That's what I do and the car stays pretty clean until next wash. Least amount of work and pretty effective level of up keep exterior wise.

Here is a good resource if you like YouTube videos. Love his videos and products.

You've got plenty of info to digest here. Larry, of Ammo, is really good and a true pro, but his products are way overpriced.

Go on Youtube and subscribe to Matt Moreman of Obsessed Garage. He has a Porsche GT3 and a Raptor and a Honda S2000, used to have an M3.

He is really good, sells lots of car wash packages with little to no markup, but puts together the things he's learned are the best, in his opinion, with no association to the product manufacturers.

When I pick up my Macan tomorrow and what I typically did to my previous cars is to first apply CQuartz ceramic coating.

Then my weekly wash is this:
- 2 bucket ONR wash (with ONR in both buckets to keep the ratio on water to ONR consistent throughout the entire process)
- I use The rag company mitts and clean 1 panel at a time.
- I then dry each panel using the rag company waffle weave towel and blotting the wash solution off. No rubbing!
- after every panel is clean I then mist with quick detailer, and buff dry with a rag company edgeless towel.
- second to last step is to use a separate mitt to clean the wheels and dry with an old microfiber.
- Finally I apply tire shine.

Every few weeks or after a road trip I will go to a coin operated wash bay and do a traditional 2 bucket soap wash. After rinsing the car after the soap I will mist with ONR before drying to keep any friction to a minimum.

Also, I never use quick detailer on a dusty car as I figure an ONR wash is just as simple. If I catch a bird bomb I typically wash that affected panel with ONR.

To those who watched the video grim posted in the first post, money aka Matt has come a long way. Besides being a successful money manager, he has Obsessedgarage.com from which he sells all things car and garage and states he’s grossing quarter mil a month. He has done countless helpful videos on YouTube covering a myriad of topics.

Living in NYC without access to an outdoor faucet to hook up a hose, what would people recommend as a minimum washing routine between visits to a hand wash? After reading all the great posts in this thread I’m now paranoid our new Macan is disintegrating in the basement garage as I type. Part two: any good recommendations for hand washes in Brooklyn? Williamsburg Car Spa looks an option but the lack of a price list on their website leads me to conclude it may be a once a quarter treat for our new baby.

Have you found any touchless car washes in your area? There are pretty common in the Philly suburbs. Many also have monthly subscription apps for unlimited washes (one per day). At the place I uses its $29 for their best touchless wash. Its not perfect but much better than washing by hand in the winter. Even during the summer if its really dirty I'll take it through the touchless first then rewash by hand.

Mahogany metallic. I absolutely love the color, but it’s not one I probably would have considered if I wasn’t buying used ( I bought it with 10k miles coming off lease). It basically looks black when it gets a bit dirty, but it does have some of the black issues with showing any imperfection. At some point I need to have swirl marks corrected and there are a couple small scratches I need to sand out
