When washing coils, we use Refrigeration Technologies Viper cleaners (especially Venom Packs) when we actually need cleaners. No matter which cleaner you use (or if you don't), you want some pressure and a high flow rate when rinsing, but keep in mind that some pressure-washers may produce too much pressure and too little flow; the sweet spot is around 300 PSI, and microchannel coils require extra caution.
