Our cars are parked outside for the majority of the time and as such a result are bombarded by a plethora of harmful substances. These can include dirt, ferrous particles (containing iron), industrial fallout, contaminants, bird mess, acid rain, road tar, tree sap, brake dust and more. These embed themselves into the paint and clear coat and over time become harmful and discolour and diminish your paints shine.
Simply washing your car will not remove all of these harmful substances and, whilst your car may look clean, deep down it is far from it! Adding a layer of wax onto this contaminated surface will provide much less protection and shine than the product was designed to achieve and you will find it much harder to apply, remove and subsequently maintain thereafter.
A ’clean surface’ is therefore defined as both above and below surface contaminants having been removed and a chemical cleaner been applied to the paint in order to remove all harmful substances.
