You run a bigger motor, or you service a few boats, and a single-litre bottle means you're mixing and topping up mid-flush. The 4-litre Salt Off SX50 concentrate gives you enough in one jug to get the job done in one go. Same chemical action as the smaller bottle – it lifts the salt residue that plain fresh-water rinses leave behind in the cooling passages. Mix it into your flush cycle, run the motor out of gear, then rinse clean. One bottle, one proper flush, no half-measures
