Dunking Biscuit's Feelin' Bubbly pH Neutral Shampoo is a high foaming wash formulated to lift and remove surface contamination without disturbing existing protection. The pH neutral, anti-marring formula is listed as safe on matte finishes and vinyl wraps, and will not compromise existing waxes or sealants, making it a sensible choice as a regular maintenance wash rather than a one-off deep clean. The maker's guidance is 20 to 30ml per 20 litre bucket, giving up to 25 washes from the 500ml bottle, and the Tutti Fruity scent sets it apart from more clinical-smelling shampoos. It works well as part of a two-bucket wash routine, alongside a clean wash mitt, a dedicated rinse bucket and a soft drying towel.
