Ive been using Chemical guys shampoo's for a long time. And I also have a gallon of there Red Citrus Wash.
Sorry to break the news, but with the current polymer sealants on the market (Menzerna, Wolfgang, Blackfire), there Citrus shampoo's will NOT remove them. Actually, in my experience, they hardly even dent them. The shampoo will remove wax and will aid greatly in getting to a stripped surface along with an APC , but they wont remove modern polymer sealants.
Not even 12% IPA will remove a sealant.
To remove a (effectively, as in remove it completely) sealant, ESPECIALLY if it is relatively fresh, you will either have to use an APC on the paint. Or my recommendation is to use a paint or pre-wax cleaner.
Ive done the whole citrus wash thing, and have washed the car twice, along with spraying APC on the panels along with the wash. And to be honest, its faster and safer to just go ove the paint , panel by panel, by hand or with a polisher, and take the 20 minutes to remove the sealant with a pre-wax cleaner or non abrasive paint cleaner.
Thats just my experience with atleast those 3 sealants.
If you are not doing some sort of polishing afterwards, its best practice to avoid using an APC to strip paint, and go for the prewax cleaner instead. APC's tend to dry the paint or even make it dull. And the ones that are paint safe, if left in spots without good rinsing will leave hazey spots in the paint until polished away.
