FLUSH Premix is compatible with both ENVIROLife Heavy Duty Engine Coolant and other proprietary engine coolants. It is non-toxic, readily biodegradable, nitrite, amine and phosphate (NAP) free, and contains a mixture of highly efficient organic corrosion inhibitors and dispersant/detergent agents that will remove mineral scale and oxide deposits.
FLUSH Premix can be used for up to 30 days in the cooling system without damaging the cooling system components, following which it must be drained out and the cooling system thoroughly flushed and rinsed out with clean and fresh water.
