Spitfire 1 of 5-  A common problem with the Spitfires are the rusted metal below the brake master cylinder.  This area is also hard to get at for immersion, so this is a perfect application for a continuous spray method.

Spitfire 2 of 5-  A small pump, garden hose, garden sprayer, plastic sheeting, and a caught basin.  Also, don't forget the duct tape.
 The area was taped off using the plastic and duct tape and the plastic was arranged to direct the flow of the rust remover to flow towards the catch basin.  About one gallon of RTU was placed into the catch basin and pump was turned on.

Spitfire 3 of 5-  This was taken about one hour into the removal process.   Note the rust that is mostly off the part and we're well on our way to complete rust removal.

Spitfire 4 of 5-  This picture was taken about 3 hours into the process.  The liquid temperature was relatively low at 50F to 65F.  All the rust was removed and this picture shows the setup again.

Spitfire 5 of 5-  The rust has been removed and this shows rusted and unrusted metal.  Note:  the dark spots along the front edge are spot welds, not rust.

Rifle Bluing- Rifle barrel was left in ambient temperature D-Rust-It (10%) for 15 minutes.  The right side of the barrel is the bluing and the left side is where the bluing has been removed.

Tap:   Picture of the same tap.  the top is severely rusted and was placed into D-Rust-It overnight.  The bottom picture is the resulting tap completely removed of rust.  Even the threads are sharp now.

Copper Watering Pot:   the bottom was immersed in D-Rust-It for 1-hour.  The bottom of the pot is brightened. Also notice that the top of the brass pouring spout was brightened ( separately dip in the rust remover).  The pot was made of copper and the pouring spout is brass.

1/2" Copper Water Pipe:  the left side of the pipe was immersed into D-Rust-It for 60 seconds and removed.  The immersed end is brightened.

Rusted Framing Square:  The framing square was left in the bed of a truck all summer.  It was placed in D-Rust-It RTU.  The rust was dissolved off front he square, leaving the painted marks in place.  It is completely usable now.

Honda Car Rotor: Rotor was half immersed in D-rust-It RTU overnight and the rust was dissolved off.  The non-rusted side looks great and it also removed the "glazing" that was on the pad contact areas of the rotor.

'34 Cord hubcaps:  The one on the right was immersed in D-Rust-It RTU overnight and it came out rust free.  The chrome was untouched.

Rust Removal Using Continuous Spray [Pic #1]: 
A severely rusted tractor Power Take Off (PTO) pulley (to the right of the tire).  Customer wanted to remove the rust without removing the pulley.

Rust Removal Using Continuous Spray [Pic #2]: 
A hose, garden sprayer, small circulator pump, catch bucket, and a 6'x6' tarp.  About a gallon of D-Rust-It RTU was placed in the catch bucket and they turned the pump on. The solution flowed from the bucket and sprayed out on the rusted pulley.  The solution dripped onto the tarp and back into the catch basin.  It was left on overnight.

Rust Removal Using Continuous Spray [Pic #3]: 
The next morning the pumps were stopped and equipment removed.  Notice the bright and rust free surface where the fluid was in contact.

Corroded Copper Grounding Wire: 
Customer had a very corroded wire that they could not a new one to replace.  Top picture shows the corroded wire, note the green near the lugs. 

The bottom picture shows the wire after being immersed in D-Rust-It RTU for about 1/2 hour.  Not the green corrosion is gone and the copper returned to its copper color. 

Comparison of a Competitors Product and D-Rust-It Concentrate: 
A bottle of Competitors product (yellow in color) and a bottle of D-Rust-It Industrial Concentrate (clear).  A light beam was shown through the bottles to enhance contents of both bottles.

Note the D-Rust-It is absolutely clear.  Also note that the competitors product has visible sediment on the bottom of the bottle.  [ See picture below for close-up]
 

Close-up of Above Picture's Competitors Product: 
Notice  the sediment on the bottom of the bottle.  If this is the Sulfur Product that the competitors say that is used to extend the life of their fluid, then its probably not in your tank.

The sediment indicates an unstable solution and this may not be transferred into your containers unless you thoroughly mixed before you poured it..

Think about it!!!  It can't be good and your paying a high price for their product.

You will not have this problem with our products.
