Anthony,
If I understand your question, you are asking if washing your car after using wax or sealant, does the soap wash the wax off the wax or sealant off. If this is what you are asking, the answer, in my opinion is both yes and no. If you use a high quality soap such as Adams, the ph is properly balanced and it will not wash the wax or sealant off. If you use a low quality soap or a harsh soap such as a dish washing soap, then yes it will. I hope that helps.
