what is the deal with water spots? i have been washing my car with my powerwasher, i have the brush and all that. im using powerwasher car wash soap. i still get major water spots. do the car washes add something to there water or what am i missing?
Usually the carwashes use either RO water or Deionized water to rinse your car. You are ina hard water area so the inorder for your car to dry spot free it will need to go through some sort of demineralization process.
