So far, I can get this:
- a generic (presumably Kontakt-U) from online order in Romania (mivarom)
- G-22 from local (in my town)
- WD-40 (from anywhere, you practically stumble on it) - but I thought this is used in stuck mechanical joints, I had one when I had my last car. Not sure if it's good for my job.
I am not cheap, but I can't afford to invest too much money (bear in mind in Romania salaries are very low) on something that has close to 0 percentage of success. I thought of spending (with air can, cleaning clothes and cleaning solution) about 10 euros (which is about 5% the price of a good card that will solve the problems close to 100%). With online shopping, transport is quite expensive here, especially from abroad, so it could end me spending 20-30 euros, and this is too much in my opinion.

WD-40 I thought is a water displacement solution. It contains a greasy substance and isn't it something we try to avoid and displace, grease (along with corrosion) ? I don't smoke

, I don't know how is it in your country, but here the smallest can of WD-40 is the price of 5-6 packs of cigarettes. If cigarettes are bought from black market (since again, few money here), price of the smallest WD-40 is about 20 packs of cigarettes.
I don't know where I can buy Isopropyl 90. I found this from internet
http://www.elfast.ro...-ipa-200ml.html , but it costs about 16 euros with transport included, too much. Are you sure this solution can be found on pharmacies ?
Thank-you all. I will buy what I can find, I wasted a lot of your time already. Anyway, not matter what I will buy and do, I am sure plenty will say I bought the wrong thing and did everything wrong.
