What is best to use as a presoak before wand washing?
The best auto car washes always seem to be the ones that apply presoak before turning on the jets. This soak is a weird blue and white foam that they apply and let sit a few minutes. It seems to make all the difference in getting grime off, including
on the front end.
Auto washes? Aw man, say it isn't so.
If you have a foamer, try Meguiars Hyper Wash for great foaming as a pre soak.
For a good soaking pre cleaner before a correction to thoroughly clean the paint, I like Einszettes W99, or Einszettes Blitz APC. Both used in the foamer.
