Wiper blades that are in perfect condition are vital for a clear view.
If the wiper blades rub or squeak, this can be as a result of the following:
– If the vehicle is washed in an automatic car wash, residues may adhere to the windshield.
These wax residues can be removed only by using window cleaner concentrate.
– The wiper blades may be damaged or worn.
– Replace damaged or worn wiper blades immediately.
As it is not possible to exclude the risk of damage to this protective coating in day to day driving, it is advisable to have the underside of the car inspected at certain intervals – preferably before the start of winter and again in spring – and the undercoating restored as necessary.
Your authorized Porsche dealer is familiar with the bodyseal treatment procedures and has the necessary equipment for applying factory approved materials. We recommend that you entrust them with such work and inspections.
Unlike conventional spray oils, undercoating and rust-proofing compounds based on bitumen or wax do not attack the sound-proofing materials applied at the factory.
Exhaust System Fire Risk
The exhaust system becomes very hot when the engine is running. Flammable material close to the exhaust system could ignite. Additional undercoating or rust protection agents on or near the exhaust system can become too hot when driving and ignite.
Effective rust-proofing is particularly important during the cold weather season. If your car is driven frequently in areas where salt has been spread on the roads, the whole engine compartment should be cleaned thoroughly after the winter to prevent salt from causing any lasting damage. A full under-body wash should also be performed at the same time.
Stainless steel exhaust tailpipes
Stainless steel exhaust tailpipes can discolor due to soiling, strong heat, and combustion residues. The original polish can be achieved again using commercially available metal polishing paste or metal polish.
Light alloy wheels
Cleaning Agents on Brake Disks
If cleaning agents (e.g. wheel cleaning agents) come into contact with the brake disks, the resulting film on the brake disks can impair braking performance.
Metal particles (such as brass or copper in brake dust) must not remain too long on alloy wheels. Contact corrosion can cause pitting.
Cleaners with an oxide-removing effect or the wrong pH value, as are commonly used for other metals, as well as mechanical tools and products, will damage the oxide layer and are therefore unsuitable.
