TFR Degreaser or Detergent?
« on: May 09, 2008, 09:44:35 pm »
Customer asked me which it is?

I said it's both.  He said it can't be, it's one or the other.

I dunno, I'm just a windowcleaner, it works so I use it.

I would see a degreaser.

Start a poll on it  ;) it is a good question, and one I have never come across myself.

What's the difference?

Detergent is a compound, or a mixture of compounds, intended to assist cleaning. The term is sometimes used to differentiate between soap and other chemical surfactants used for cleaning purposes.

this is what come up for degreaser:

Parts cleaning is essential to many industrial processes, as a prelude to surface finishing or to protect sensitive components. Electroplating is particularly sensitive to part cleanliness, since molecular layers of oil can prevent adhesion of the coating. ASTM B322 is a standard guide for cleaning metals prior to electroplating. Cleaning processes include solvent cleaning, hot alkaline detergent cleaning, electrocleaning, and acid etch. The most common industrial test for cleanliness is the waterbreak test, in which the surface is thoroughly rinsed and held vertical. Hydrophobic contaminants such as oils cause the water to bead and break up, allowing the water to drain rapidly. Perfectly clean metal surfaces are hydrophilic and will retain an unbroken sheet of water that does not bead up or drain off. ASTM F22 describes a version this test. This test does not detect hydrophilic contaminants, but the electroplating process can displace these easily since the solutions are water-based. Surfactants such as soap reduce the sensitivity of the test, so these must be thoroughly rinsed off.


degreaser comes up with simalar to the above  but covers the above so imo i NOW DO NOT HAVE A CLUE WHAT TO SAY BUT i AM WORKING ON THE ANSWER

Anything that shifts dirt is a detergent, anything that shifts grease/oil is a degreaser.

Fairy is a hard one really. Any detergent that removes oil or grease could be classed as a degreasant but if it just moves the oil around without lifting it then it's still a detergent.

Ian, I know exactly how long any length of string is if anybody ever asks me. 

Answer: Twice it's length from it's centre to it's end, lol

you did not answer the question Wayne, it is a hard one, and a very good post IMO, I thought degreaser first off but can it be both ?

www.nfsmi.org/Information/adult_resource/lessons/lesson11.pdf

Definitions:-   
Degreaser: Substance that dissolves grease
Detergent: Substance that loosens soil from the surface

So to me that means that a detergent loosens the grease enough for it to be free to float on the surface of water where as a degreaser will actually disolve the grease in to the solution.

Very interesting so far guys.

So why do we use a Degreaser (which dissolves oil and grease) to clean dirt (which a detergent will lift) from conservatory roofs etc.
