Diamond Performance 2in1 Car Shampoo is a concentrated wash and wax shampoo, diluted at a stated 200:1 ratio so a small measure covers a full wash. The mild, pH neutral formula is designed for hand washing painted bodywork and works with a standard wash mitt or sponge as part of a two bucket routine. Because it combines cleaning and a wax finish in a single step, it suits a routine weekly wash rather than a full decontamination stage. It pairs well with a dedicated pre-wash or snow foam to lift loose dirt first, a soft wash mitt, a grit guard bucket, and a microfibre drying towel to finish. It sits within the wider Diamond Performance car care range.
