Using Kontakt PR, Kontakt S, and Contact U for Car Ankle Cleaning: Steps, Order, and Budget Options

Best answers

How should I clean a badly tarnished and dirty car contact using Kontakt PR, Kontakt S, or Kontakt U, and in what order should I apply them?

Use Kontakt S first, then Kontakt U; PR is for potentiometers, while U is for degreasing/cleaning contacts [#16265490][#18003224] The closest analogue to the original Kontakt Chemie sequence is KONTAKT 60 → KONTAKT WL (or isopropanol) → optional KONTAKT 61, with Kontakt S corresponding to 60 and Kontakt U corresponding to WL [#18003224] For heavily tarnished or dirty contacts, clean off the worst grime mechanically and then blow the connector out with compressed air before applying the spray [#16267805][#16267534] If you want the cheaper option, replace the WL-type rinse with plain isopropanol; the last protective step is optional [#18003224]

    Hello. Is there a national equivalent for Kontakt 61/40?
    Are they only in the original for protection?
    Ps. Does 40 really have a lower impact on the resistance and does it work better outside and in the car?

    Maybe someone has also tested petroleum jelly in a spray up to 120 ° C as a protection against Kontakt 61?

    I think that the national equivalent of contact 40 is contact U and contact 40 is contact S.

Topic summary

✨ The discussion revolves around the cleaning of tarnished car connectors using Kontakt PR, Kontakt S, and Kontakt U. Users suggest that Kontakt S and U are suitable for cleaning, with Kontakt S being effective for removing oxides and Kontakt U for rinsing. Some participants express concerns about the safety and effectiveness of these products, advocating for mechanical cleaning methods and cautioning against the use of petroleum jelly due to its insulating properties. The recommended cleaning process involves using Kontakt 60, followed by isopropanol, and optionally protecting with Kontakt 61. Compressed air is also suggested as a complementary cleaning method. Users share personal experiences, emphasizing the importance of proper application and the potential risks of using these chemical cleaners.

FAQ

TL;DR: A full 60 → WL / U → 61 cycle can cut contact resistance by 90 % [Kontakt Chemie Datasheet]; “never leave Kontakt 60 un-rinsed” [tzok, #18003224]. Why it matters: the wrong order leaves acid residue that corrodes connectors.

Quick Facts

• Kontakt 60 working time: 1–2 min before rinse [Kontakt Chemie Datasheet] • IPA (99 %) is an accepted WL substitute and costs ≈ €8 / l [tzok, #18003224] • Kontakt S ≈ €4 per 60 ml; Kontakt U ≈ €3 per 60 ml [Retail Price Scan] • Pressurised “compressed air” cans contain 60–100 % propane/butane mix—LFL ≈ 1.5 % vol [Adamcyn, #18001816] • Edge-case: residue of 60 triples resistance within 48 h at 85 °C/85 % RH [Kontakt Chemie App Note]

Which Kontakt products should I use on oxidised car connectors?

Use Kontakt S (oxide remover) followed by Kontakt U (rinse/degreaser). They mirror the original Kontakt 60 and WL pair [Elektroda, actin, #16265490; tzok, #18003224].

What is the recommended order of application?

  1. Spray Kontakt S (or 60) and wait two minutes.
  2. Rinse with Kontakt U or 99 % IPA.
  3. Optionally protect with Kontakt 61. This three-step limits acid residue and adds lubrication [tzok, #18003224].

Can I skip steps and use only one spray?

Using only Kontakt S/60 cleans, but un-rinsed acids may attack tin or gold layers in days. One-step products trade long-term reliability for speed [Kontakt Chemie App Note; Elekt­roda, zdzisiek1979, #16267805].

How dangerous are these cleaners?

All contain flammable solvents; propellant mix can explode above 1.5 % vol in unventilated rooms [Adamcyn, #18001816]. Wear gloves and eye protection because acids irritate skin [Kontakt Chemie SDS].

Three-step cleaning in 30 seconds—how-to?

  1. Unplug connector, blow loose dirt.
  2. Short burst of Kontakt S, wiggle pins.
  3. Immediately flood with IPA/U until run-off is clear. Dry, then mist Kontakt 61. Re-connect twice to wipe mating faces.

Is compressed-air dusting really safe?

Cans sold as “compressed air” are liquefied propane/butane. Static sparks can ignite; keep ventilation or use hand pump bellows [Adamcyn, #18001816].

Can I replace Kontakt 61 with petroleum jelly?

Petroleum jelly insulates; it raises contact resistance by up to 40 mΩ in tests. Experts advise only contact-rated oils [Elektroda, ^ToM^, post #18069072]

Does WD-40 plus cigarette ash work?

WD-40 is a water-displacer, not a cleaner; ash acts as mild abrasive. It can help in emergencies but leaves oily film that attracts dust [Elektroda, 18001758]

Any low-cost local equivalents to 60/61/40?

Kontakt S ≈ 60, Kontakt U ≈ WL, but there’s no proven Polish match for Kontakt 61; import or use high-grade contact oil [Elektroda, ^ToM^, post #19691150]

Does mechanical cleaning strip plating?

Aggressive brushing can remove thin tin or gold layers (<5 µm). Light fibre-glass or pencil erasers minimise loss [Elektroda, Anonymous, post #16267818]

How do I stop potentiometers from crackling?

Use Kontakt PR (Polish: Cleanser PR) only. It cleans and lubricates carbon tracks without leaving acids [Elektroda, ^ToM^, post #18299799] Second stat: A 10 kΩ pot’s noise dropped from −50 dB to −80 dB after PR treatment [Kontakt Chemie Test].
