In everyday life, this drug has found wide use after it was discovered that it perfectly revives rusted and frozen locks. It easily penetrates into hard-to-reach places and the smallest cracks and crevices. And for all its popularity, it is also not cheap.
The composition that we are considering today is an experimental version of WD 40. The proposed proportion of chemical elements may change, and is not the final version, since the original composition of the “WD” remains a secret. Based on the known components, the author of the video proposes to make a mixture similar in characteristics to the known drug.
Where did the idea come from?
This is all due to the considerable price of the original WD 40. A small bottle of 100 ml will cost about 200 rubles, and a large bottle of 400 ml will cost up to 400 rubles. Thanks to the aerosol, the consumption of the drug is quite high.
For rare home use, such expenses will not burden the budget. Motorists often have to resort to its help, and for mechanics from a car repair shop, where they use it in liters, this is quite an impressive load.
The approximate composition, known from the American Chemical Safety Data Sheet, includes:
- 50% - solvent (white spirit);
- 25% - displacer (carbon dioxide or carbon dioxide);
- 15% - mineral oil.
The last 10% comes from secret ingredients called inerts. There is an assumption that these are wax-containing substances.
Let's try to repeat the wonderful WD (Water Displacement) water “displacement” solution.
Required Ingredients
- White Spirit;
- Refined gasoline;
- Mineral oil;
- Paraffin.
For the mixture you will need a 0.5 L plastic container with an air freshener spray or for watering flowers.
Preparing WD-40
We buy nephrases or petroleum solvents (White spirit and purified gasoline) at a hardware store or supermarket. They are inexpensive, around 50 rubles. Galosha gasoline is suitable as an active solvent with a low octane number.
As for the oil, you only need 75-100 ml. On occasion, you can ask your neighbor in the garage for this amount, because every motorist has a “duty” canister for refilling. Based on experience, mineral oil is the best option.
Paraffin, also a product of petroleum refining, is necessary as a water-repellent element that creates a film on the treated surface after applying the drug. Melt a small amount of it and add it to white spirit. Do not overdo it with the quantity, since in the cold it can lead to thickening of the entire composition.
Advice!
If the drug is used for automotive needs (loosening bolts, clamps, clamps, terminals, gaskets, etc.), paraffin does not need to be added. And for home use, for example, to clean dried or frozen keyholes, hinges, deadbolts, this ingredient will provide additional protection against moisture and corrosion.
A plastic bottle with a removable sprayer is ideal for applying the solution. Today they sell air fresheners, cosmetics and even medicines. You can also buy the puller separately and attach it to any suitable bottle.
Pour the oil into a bottle, followed by white spirit with or without paraffin and purified gasoline. The proportion is as follows:
- White spirit – 4 mass fractions;
- Refined gasoline (“Galosh”) – 3 mass fractions;
- Mineral oil – 1 mass fraction.[list]
It is most convenient to fill the container by dosing the ingredients with a syringe. Shake the prepared solution thoroughly and use it!
Safety precautions
Before preparing the drug at home, do not forget that its main components are extremely flammable. When mixing the solution and using it, wear protective gloves.
Original WD 40 cannot be extinguished with water. The homemade mixture also contains a high content of flammable substances, which if ignited, water will not have any effect.
Therefore, it is recommended to prepare and use the solution away from open sources of fire, heating devices and powerful lamps that emit heat. Ventilation must be provided in enclosed spaces.
Otherwise, this recipe for preparing “vdshki” is quite acceptable and economical.One liter of solution costs about 100 rubles, not counting the cost of oil, which is easy to obtain, and paraffin waste (candles). And there are probably spray bottles in every household. A store-bought version in this volume will cost 1200-1500 rubles. There is something to compare and something to strive for!
