Cleaner & Protectant for Microchannel Coils Protect your heat exchanger coils using QwikBright instead of just cleaning them. A blocked or filthy condenser coil can lower unit performance, raise compressor pressure ratio, accelerate corrosion, and diminish sub-cooling. However cleaning microchannel coils must be done with caution. Microchannel coil manufacturers advise only using a pH neutral cleaner and never using an acidic or alkaline cleaner, since any cleaner with a pH below 6 (acidic) or over 8 (alkaline) will hasten corrosion and cause coil leaks. QwikBright is a neutral pH microchannel coil cleaning and protectant that is particularly created to swiftly penetrate and remove grease, filth, grime, lint, dirt, dust, and bugs while also imparting a protective coating. Yes, QwikBright has a molecular metal protectant to help prevent corrosion while maintaining thermal performance. QwikBright may be used indoors or outdoors on any type of microchannel heat exchanger, and it doesn't need to be rinsed when used on evaporators.
