I have to admit to being a fan of Autoglym, and have used their products for many years, especially Autoglym Bodywork Shampoo Conditioner. This particular product comes in various sized containers. I received my latest batch as a Christmas present this year, something which is becoming rather a habit, so I have lost touch with the prices being charged. I have however, looked up costs online, and you will find the cheapest is £5.10 for the half litre, £7.64 for the one litre, the more cost effective size of two and a half litres will set you back £16.33, and if you can justify it, buying a five litre drum would be £24.50, a bargain if you want to share with friends, for example! To be honest you will get even better value buying these products at car shows, where they are available at discounted prices.
The most economical way to buy is to go for the biggest you can afford. These white containers have a screw cap, which in turn have a flip top lid. This is a very practical idea, as you can flip open the cap, squirt a little into your bucket, then flip the top closed, even with wet hands.
The product itself is called Autoglym Bodywork Shampoo Conditioner, and is concentrated. As the title suggests, it's a shampoo plus conditioner, which will clean off road grime, and leave a thin protective film on your vehicle, even when rinsed off. This is pH neutral, and you need to pour two caps full (20 ml) of the shampoo into ten litres of warm water in a bucket. The vehicle should have been hosed down before you start. I find it easiest to wash one half of the car, then rinse, before doing the other side. You should wash with a circular motion, using a soft clean sponge. Try not to allow the solution to dry on the car, and keep the sponge clean. Rinse well, making sure all the solution is rinsed from nooks and crannies, then either dry with a wash leather, or use a rubber blade.
After the car is dry, it is recommended you apply a good quality car polish. I personally use one by Autoglym, but the choice is yours. You can use this shampoo on all car surfaces, including alloy wheels, glass, and tyres, although I leave wheels and tyres until last, and then use a soft brush.
Autoglym Bodywork Shampoo Conditioner is a British product, produced in Letchworth, and is by Royal Appointment to both Her Majesty the Queen, and HRH The Prince of Wales. The company has a website.where you can see all the product range, and there is even a section where you can ask the experts questions! See it at Autoglym.
I will just mention a small safety note, it is recommended that if you have sensitive skin, you should wear PVC gloves, and as usual, if any gets into the eyes, flush with plenty of clean water.
This shampoo is selected by Aston Martin Lagonda Ltd, Jaguar cars Ltd, and also Morgan Motor Company Ltd.
I would say this is one of the easiest products of it's type to use, and probably one of the best. I do however, believe that regular cleaning with average product, will be more beneficial than an occasional use of a good one. Little and often is the best way.
