The project to make DIY Alklanet aka RevKlanet, AlklaNEP, Lolklanet or Alklanetniet. Why ? Alklanet is awesome cleaning agent, but is kinda expensive. Can we make something ourselves? Alklanet is a commercial product, with a secret composition. Howewer de MSDS reveals the most common chemicals.

Alklanet facts

  • blue
  • pH 5.5 - 7 according to MSDS, Litmus measures 6
  • 5 -10% 2-Butoxyethanol
  • ? % surfactant
  • ? % ethanol


  • Production of test batches : Making revklanet.jpg


Recipe V0.1

Al %weight, For 200 ml. These will give only apporximate concentrations.

  • 20 g Eco-Aceton from "De Parel" from hornbach
  • 10 g hard soap
  • 10 g ethanol ( Available from drugstores as 95% ethanol for cleaning)
  • 160 g water

Feedback

  • Trouble dissolving all the soap, also feels very soapy, probably way too much.
  • pH 8
  • thrashed

Recipe V0.2

Al %weight, For 200 ml. These will give only apporximate concentrations.

Feedback

  • smells very nice

Recipe V0.3

Composition

For 200 ml solution, all wt%. These will give only approximate concentrations, as non of the ingredients are pure.

  • 20 g ( 10% ) Eco-Aceton from "De Parel" from hornbach
  • 5 g ( 2.5% ) mirasol 2000 - tenside / wetting agent. MSDS
  • 10 g ( 5%) ethanol ( Available from drugstores as 95% ethanol for cleaning)
  • 172 g ( 82% ) demineralised water

Economics

  • Eco-Acetone - 6.80 eur /1000g = 0.0068 EUR/g
  • Mirasol : 11.95 eur/ 250g = 0.0478EUR/g
  • Etos Ethanol 2.29 eur/100g = 0.0229 EUR/g
  • Aro Demiwater : 2.65 eur / 5000 g = 0.00053 EUR/g
  • Price per liter : 100×0.0068+25×0.0478+50×0.0229+1000×0.00053 = 3.55 per liter that is approx 1/3 of Alklanet rpice, 10 Eur/l
  • This is very expensive since we are using most expensive source of ethanol and surfactant comes from a photographic materials supplier.

Feedback

  • pH 6-7
  • Gori: Cleaned the outside glass of the door in the workshop. Seems to remove mystery spots better than Alklanet
  • Gori: when used on a tables, no perceivable difference.
  • joepie91: v0.3 lijkt prima te werken, net tafel mee schoongemaakt, beetje vreemd geurtje maar verder prima

Recipe V0.4

For this version, we want to improve both the economics and performance.

  • Replace ethanol with Isopropyl alcohol : Better degreasing properies, and much cheaper
  • Find an alternative surfactant / tenside, in bulk 1/10th of the price may be possible

Composition

For 200 ml solution, all wt%. These will give only approximate concentrations, as none of the ingredients are pure.

  • 20 g ( 10% ) Eco-Aceton from "De Parel" from hornbach
  • 5 g ( 2.5% )  ??? surfactant / tenside
  • 10 g ( 5%) IPA ( Available from Revspace, 4 EUR / l)
  • 165 g ( 82% ) demineralised water

Testing

  • Test setup : RevKlanetTestSetup.jpg
    • Compare : Demineralised water, Alklanet, RevKlanet V0.2, RevKlanet V0.3
  • Testing protocol : TestingMaterials.jpg
  • Apply and dry for 30 minites
    • Wok oil
    • Ketjap Manis
    • Ketchup
    • Meggele garlic butter
  • Attempt cleaning with a clean microfibre cloth and report results
    • Spray area with a single pump (we are using old Alklanet bottles)
    • Wipe 1/3 immediately in a single downward stroke
    • Wait 10 seconds then wipe 2nd 1/3 with a single stroke
    • Then clean the final 1/3 until clean
    • Then clean the entire area with the same product


Results V0.2 and v0.3

  • Overall findings : Both V0.2 and V0.3 work as good as Alklanet. V0.3 dries fastest, and degrease markedly better than Alklanet. Probably because we use the a higher concentration of alcohols, and the wetting agent greatly helps as wel.
