I wonder if there is any information regarding what will each shampoo strip. Citrus wash from CG will for sure strip wax, but how about optiseal?
Any soap that claims to strip wax/sealant would likely be not good for your skin. You'd have to at least lightly polish any respectable coating to remove it.
I think he was referring to just the citrus wash. Having said that, I often use a strong mixture of citrus wash and gloss to remove waxes/sealants as per the manufacturer directions.
