A non-toxic, ready-to-use anti-freeze for boat engines and boat and caravan freshwater systems, providing cold weather protection down to -46°C (-50°F).
Star brite Pink Non-Toxic Anti-freeze is a ready-to-use anti-freeze for boat engines and boat and caravan freshwater systems, providing cold weather protection down to -46°C (-50°F).
Star brite Non-Toxic Pink Antifreeze is safe for use in freshwater systems during the winter, however, it is not safe to consume and must be drained from the system before using the fresh water again.
In the spring when you wish to use the water system again for drinking or washing make sure you flush the system through for at least 20 minutes with fresh water until all the coloured antifreeze has disappeared, then refill the tank with fresh water.
Before refilling the fresh water it might be a good time to use a tank cleaner such as Elsan Water Tank Cleaner or Puri Sol Water Tank Cleaner.
Star brite -46°C Burst Protection Non-Toxic Anti-Freeze provides up to -46°C based on a copper pipe filled with this anti-freeze. A PVC pipe filled with this anti-freeze is likely to burst at -23°C. If temperatures are likely to drop below minus 23°C then it is recommended to use an anti-freeze designed to protect against harsher conditions.
This antifreeze contains corrosion inhibitors which protect against rust and corrosion of aluminium, copper, solder, and brass. It will not harm rubber or other hose and gasket material.
Star brite Non-Toxic Pink Antifreeze should not be diluted and should be used neat from the bottle.

If there's a question you have about Star brite Non-Toxic Pink Antifreeze see if it has been asked already or ask us the question and we will attempt to answer it for you.
Answer: Drain down the fresh water tank and system completely. Drain and bypass any hot water calorifier tanks (connect the inlet and outlet hoses together). Pour the neat antifreeze into the empty fresh water tank. Turn on the water pump to pressurise the system. Open each tap on board starting with the furthest from the tank, running until pink fluid flows out, then turn it off. Repeat for all taps and outlets.
Answer: No. It contains built-in corrosion inhibitors designed to protect brass, copper, aluminium, and solder from rust and scaling. It is completely safe for rubber hoses, gaskets, and pump components.
Answer: Temperature protection varies depending on your pipework: Copper Pipes: Provides burst protection down to -46°C (freeze protection to -11°C). PVC / Plastic Pipes: Provides burst protection down to -23°C (freeze protection to -11°C). If you expect temperatures below -23°C in systems with PVC pipes, consider a higher-rated formula.
Answer: No. Star brite Non-Toxic Pink Antifreeze is supplied ready to use and must be used neat directly from the bottle. Diluting it with water will reduce its anti-freeze and corrosion-inhibiting properties.
Answer: Yes. It is specially formulated to be safe for winterising freshwater systems in boats and caravans, as well as engine cooling systems. While non-toxic, it is not safe to consume. In spring, you must flush the water system thoroughly for at least 20 minutes with fresh water until no pink tint remains before drinking or using the water.
