Published on

Detergents with the right chemistry can reduce the corrosive effects of magnesium chloride and calcium chloride and add additional protection. Are an economical solution to enhance the protective qualities of coatings and can easily be integrated into routine maintenance. Need to be applied to the undercarriage to maximize the anti-corrosion benefits.

Cleaning in the Age of Magnesium Chloride

  1. 1. CLEANING IN THE AGE OFMAGNESIUM CHLORIDETony VertinVer-tech Labs, Rockford, MNwww.ver-techlabs.comwww.vtlvehiclecare.com
  2. 2. The Corrosive Effects of Magnesium and Calcium Chloride• Protective coatings are a widely used corrosion control solution and are generally applied at point of manufacturing• An alternative solution to reducing the effects of corrosion can be the integration of a cleaning product into routine maintenance regimen
  3. 3. Cleaning large vehicles Photos courtesy of Belanger, Inc.
  4. 4. Temperature Time Mechanical Action Water Quality Chemical ActionThe five factors of cleaning are like pieces of a pie. Adecrease in one of the factors means that anotherfactor(s) will have to be increased to compensate andprovide the desired cleaning results.
  5. 5. Time• in general, soaking time increases cleaning ability• point of diminishing return• soils and oil may redeposit on surface• optimum dwell time for: presoaks = 30-45 seconds bug remover = 1-2 minutes
  6. 6. TemperatureThree Types • Ambient • Vehicle • Chemistry (product & water)Effects of temperature on cleaning • Temperature = Activity (atoms get more “excited” when heated) • Some Limitations • General Guidelines are 110 - 120 F on vehicle surface
  7. 7. Mechanical Action• Friction • Cloth, brushes, bristles, foam fabric• Touch-Free • Water Pressure (psi) • Water Volume & Impingement • Speed of Cycle
  8. 8. Chemical Action• Reduce static charge to release certain soils• Break down soil physical bonds to the vehicle surface• Solubilize/disperse road film
  9. 9. Water Quality• Water hardness• Total Dissolved Solids (TDS)• pH• Total Alkalinity• Metals (Iron, Copper, Manganese)• Water treatment - RO, DI, Reclaim
  10. 10. Do we need to consider a Sixth Factor? “Desaltification”
  11. 11. Detergent Components • Acids • Alkalis • Surfactants • Conditioners • Solvents
  12. 12. Functions of Acidic Detergents Low pH or pH<7 •Water hardness compatible •Cleans and brightens chrome and glass •Excellent for most inorganic soils •Buffers the next step •Excellent rinsing properties •Aids in drying
  13. 13. Functions of Alkaline Detergents High pH or pH>7 •Effective against particulate and oily soils •Detergency •Saponification •Break down organic soils •Acid soil neutralization
  14. 14. Functions of Surfactants• Solubilization and emulsification of soil• Enhance rinsing• Wetting of surfaces• Penetration of soil• Displacement of soil• Foam or defoam• Antimicrobial – limited
  15. 15. Functions of Conditioners• Prevent calcium and magnesium salts from precipitating and/or adhering to surfaces.• Chelate • “Claw” for metal ions like Mg or Ca• Crystal modifier • Functions like a chelate • Prevents metal ion precipitation or scale formation at extremely low dilutions
  16. 16. So back to the typical washing of alarge vehicle…generally a neutraldetergent and/or an alkalinedetergent is used.Why is it not effective todayagainst magnesium and calciumchloride?
  17. 17. The Neutral Detergent • Neutral Foam Shampoo • Similar to Pot and Pan Dish Soap • Used in friction washes • Provides lubricity and detergencyPhoto courtesy of Belanger, Inc.
  18. 18. Neutral Detergent added to Calcium Chloride Solution
  19. 19. Incompatibility
  20. 20. Neutral Detergent and Chlorides• Incompatible with Magnesium or Calcium Chloride.• May create very small particulate in the brushes and cloth of the wash resulting in abrasion to surface of vehicle
  21. 21. The Alkaline Detergent Alkaline Detergents (pH >7 or High pH) • Saponification • Effective against particulate and oily soils • Acid rain • NeutralizationPhoto courtesy of Belanger, Inc.
  22. 22. Alkaline Detergent added to Calcium Chloride Solution
  23. 23. Insoluble chlorides forming
  24. 24. Alkaline Detergent and Chlorides• Shocks the chlorides out of solution similar to how a water treatment facility reduces water hardness• Creates insoluble magnesium or calcium chloride that is more difficult to remove from vehicle
  25. 25. The alternative solution – Low PH detergent• Discovered as part of the touchless car wash two step cleaning process.• Total desaltification of metal and painted surfaces• Can be used as a one step detergent in a friction wash or as step 1 in a two step touchless wash
  26. 26. Low pH Detergent added to Calcium Chloride Solution
  27. 27. Solubilizing
  28. 28. Low PH Detergent and Chlorides• Solubilizing both calcium and magnesium chloride to aid removal and prevent subsequent corrosion
  29. 29. An additional benefit?• Surfaces cleaned using the Low pH approach have been very resistant to subsequent corrosion• Un-rinsed Low pH detergent on bare metal provided additional protection• Tests reveal that the correct Low pH detergent applies a conversion coating to the metal
  30. 30. Conversion CoatingA conversion coating is the result of thereaction between a metal surface withanother chemical that provides a greaterprotection against foreign corrosivesubstances than that provided for by themetal itself.
  31. 31. an example of conversion coating• Plate treated with low • Reverse side of plate – pH detergent no treatment
  32. 32. The Result This truck based in Michigan has been washed for the last two years with a Low PH detergent

  40. 40. Detergents with the rightchemistry can work for you –but only if the detergent isapplied where it counts
  41. 41. Detergents with the right chemistry… • Can reduce the corrosive effects of magnesium chloride and calcium chloride and add additional protection • Are an economical solution to enhance the protective qualities of coatings and can easily be integrated into routine maintenance • Need to be applied to the undercarriage to maximize the anti-corrosion benefits
