Hi,
A newbie on here but rather more experienced on the detailing world forum (if you want to see just how awesomely cars be be "cleaned" pop along to the detailing world site
Have a look at CarChem - a small company in Nottingham who are manufacturers rather than resellers. Their 1900:1 shampoo is one of the "benchmark" shampoos (obviously there are others) and is a pure shampoo so doesn't add any "wax" or anything else - it cleans. They have a whole range of products and their customer service is superb - you're dealing directly with the company.
Similarly have a look at Bilt Hamber. Many may well have come across their superb anti corrosion products and they have an extensive and hugely respected range of "cleaning" products also. Their quick detailer (Auto QD) is very good.
As with most things there's dozens of possible alternatives and everyone has their favourite "go to" products. But you can do far worse than washing in 1900:1 and then applying Auto QD.
Simple, quick and very effective.
Happy car cleaning.
Andy.
PS I'm not connected to either CarChem or Bilt Hamber. Just a very happy customer who purchases many of their products.
PPS I would have put the internet links in but they don't seem to be working.
