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
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.
- 20 g Eco-Aceton from "De Parel" from hornbach
- 2 g hard soap (Nivea creme soft)
- 10 g ethanol ( 96% ethanol from Etos)
- 168 g water
Feedback
- smells very nice
- cleans well, but less than Alklanet or 0.3
- leaves a bit more streaks than Alklanet
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
Product | Price per unit (€) | Unit (g) | Price (€/g) | Amount in recipe (g/l) | Costs (€/l) | link |
---|---|---|---|---|---|---|
Eco-Acetone | 6.80 | 1000 g | 0.0068 | 100 | 0.680 | https://www.pearlpaint.nl/nl/merken-producten/eco-line/aceton-eco_586/ |
Mirasol | 11.95 | 250 g | 0.0478 | 25 | 1.195 | https://www.macodirect.de/en/chemistry/machine-chemistry/4690/tetenal-mirasol-2000-antistatic-wetting-agent-250ml MSDS |
Ethanol | 2.29 | 100 g | 0.0229 | 50 | 1.145 | https://www.boodschappenbestellen.com/bestel/etos-alcohol-96/ |
Demiwater | 2.65 | 5000 g | 0.00053 | 1000 | 0.53 | https://www.makro.nl/cat/nl/products/product/1522040001001 |
TOTAL | - | - | - | >1000?? | 3.55 |
- 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
- Cleans very well, but leaves slightly more streaks than 0.2
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 :
- Compare : Demineralised water, Alklanet, RevKlanet V0.2, RevKlanet V0.3
- Testing protocol :
- 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.
