Using washing up liquid to wash a car!

There are a surprising amount of people who think that its a waste of time buying special car shampoo, when you have washing up liquid to hand. This is a huge mistake to make!

Yes you may use it, and the car may look clean - but the contents of washing up liquid is actually harmful to car paint. Not only will you be taking off any wax or polish that's on the paint surface, the washing up liquid will react with the paint and in a few years time will basically be ruined. The bodywork may even start to corrode as a result of not having decent paint protecting it.

It could look like this if you continue this shocking behaviour:

So - don't risk it and don't be a cheap arse.  Buy some proper car shampoo and ensure your car paintwork is protected for as long as possible!
