Blue Fire Ultrasonic Cleaner is a phosphoric acid concentrate for ultrasonic parts cleaning tanks, sold in 1L (lots of 12), 5L (lots of 4) and 20L packs.

What it does

Blue Fire is Sierra's concentrated solution for ultrasonic cleaning tanks, normally mixed at about 10:1. The SDS lists orthophosphoric acid at over 40% with a surfactant blend under 3%, a pH of about 1 and a specific gravity of 1.38. In the tank, the acid and surfactants work with the ultrasonic action to lift grime and deposits from small parts. As a strong acid it is corrosive to skin and metals, a Class 8 dangerous good and a Schedule 6 poison.

Where to use it

Mechanical, small engine and parts reconditioning workshops that run ultrasonic tanks. Sierra rules out magnesium. For spin washers, see Turbo Spin Wash Parts Powder, or browse all degreasers.

How to use

1. Gear up with goggles, a face shield, gloves to the elbow, an apron and rubber boots.
2. Fill the tank with water first, then add Blue Fire at around 10 parts water to 1 part concentrate.
3. Run the cycle to the tank maker's instructions.
4. Rinse the cleaned parts in clean water.
5. Send spent solution to a licensed waste contractor, or treat it as your local authority directs.

Safe on / avoid

Never use it on magnesium. The SDS also lists alloys, glass, leather, natural rubber and strong caustics as incompatible, and warns it reacts with metals to release flammable hydrogen. Test any alloy part first, and never mix it with alkaline degreasers. Read the Safety Data Sheet before use.
