I currently use DG #901 and absolutely love it. I'm running low on the product and thinking about either picking up another bottle or trying out Optimum Car Wash. Price wise they are almost identical so that is not the issue. Has anyone used both products? If so, which did you prefer? Are there any cons with using Optimum? I've been using DG for a couple of months now and wouldn't mind trying out a new shampoo. Any input would be appreciated.
