Frequently Asked Questions
Is pressure washing safe for classics?
Yes with low pressure and good technique, but avoid chipped paint, seals and fragile trim.
What PSI is safe?
Lower is safer, and wide-angle nozzles keep pressure on the paint gentle.
Do I need a foam cannon?
Not required, but it makes pre-washing noticeably more effective.
Let the foam and water do the work. The less you touch the paint, the longer it stays flawless.
