Dilution of pushsalo with white spirit: proportions, technique and errors

What is pushsalo and why dilute it with white spirit?

Pussalo (or cannon fat) is a thick preservative lubricant based on petroleum oils, widely used in auto repair to protect metal surfaces from corrosion. Its unique composition allows you to create a long-term protective layer that is resistant to moisture, salt and mechanical stress. However, due to its high viscosity, it can be difficult to apply push salo in its pure form, especially on vertical surfaces or in hard-to-reach places.

This is where it comes to the rescue white spirit - a universal solvent that not only reduces the thickness of the lubricant, but also improves its penetrating properties. A diluted pushsal is more easily distributed with a brush, spray or swab, and after the solvent evaporates, it retains all its protective characteristics. But here lies the main danger: Incorrect proportions or dilution technique may negate benefits.

In this article we will look at how to mix components correctly, what proportions to use for different tasks (from anti-corrosion treatment to preservation of parts), and also reveal critical errors that lead to deterioration of the protective properties of the mixture.

Composition and properties of pushsalo: why it needs to be diluted

The classic pushsalo consists of:

• 🛢️ Mineral oils (up to 90%) - a base that provides lubricating and protective properties.
• 🧴 Thickeners (paraffins, ceresins) - impart thickness and heat resistance.
• 🔬 Antioxidant additives — extend the service life of the lubricant.
• 🛡️ Corrosion inhibitors - active components that block rust.

Thanks to this composition, pushsalo can withstand temperatures from -50°C up to +50°C, does not drain from vertical surfaces and retains its properties for up to 2–3 years. However, high viscosity creates problems:

• 🖌️ Difficult to apply to ribbed surfaces (e.g. spars or rapids).
• 🕳️ Does not penetrate microcracks and welds.
• 🚫 Forms a thick layer that can peel off during vibrations.
• ⏳ Increases processing time (requires heating or mechanical distribution).

White spirit (nefras-S4-155/200) solves these problems by temporarily reducing viscosity. But it's important to remember: the solvent evaporates, and it is the push salo that provides the protective properties. Therefore dilution by more than 30% leads to the formation of a porous film, which provides poorer protection against moisture.

Dilution proportions: table for different tasks

The optimal ratio of pushsalo/white spirit depends on the purpose of use. Below is a table with proven proportions and areas of use:

Ratio (pushsalo: white spirit)	Mixture viscosity	Scope of application	Application method
100 : 0	Very thick	Preservation of threaded connections, processing of thick metal sheets	Brush, spatula (heated)
90 : 10	Thick but flexible	Anti-corrosion treatment of thresholds, side members, bottom	Brush, swab
80 : 20	Average	Processing of welds, internal cavities, wheel arches	Sprayer, brush
70 : 30	Liquid	Penetration into microcracks, treatment of rusty surfaces before painting	Sprayer, immersion
50 : 50	Very runny	Washing parts from old grease, temporary protection (up to 3 months)	Immersion, spray

⚠️ Attention: Ratio 50 : 50 and higher is considered emergency and is used for cleaning or short-term protection only. For long-term preservation, the maximum permissible dilution is 70 : 30.

When working with a sprayer, it is recommended to first strain the mixture through metal sieve or nylon stockingto avoid nozzle clogging. Also note that at temperatures below +10°C the viscosity of the mixture increases - in this case, you can temporarily increase the proportion of white spirit by 5–10%.

Step-by-step instructions: how to properly dilute pushsalo

The dilution process requires care, as improper mixing can lead to separation of components or the formation of lumps. Follow this algorithm:

1. Preparing pushsalo.

   If the lubricant was stored in the cold, move it to a warm room (+18...+25°C) for 12–24 hours. To speed up you can use water bath (do not heat above +40°Cso as not to destroy the additives!).

2. Choosing white spirit.

   Use only pure solvent (GOST 3134-78). Check for sediment: if there is a cloudy layer at the bottom of the canister, drain the top or strain through a filter.

3. Mixing.

   Add white spirit to the pushsalo in small portions (5–10% of volume), stirring thoroughly after each addition. Optimal use paint stirrer or a drill with an attachment at low speed.

4. Checking consistency.

   The finished mixture should flow from the brush slow jetwithout forming drops. If the mixture is too liquid, let it sit for 1-2 hours - some of the solvent will evaporate.

⚠️ Attention: Never mix pushsalo with gasoline, acetone or solvent! These solvents destroy the structure of the lubricant, depriving it of its protective properties. Also avoid metal containers - reaction with additives can lead to oxidation.

To check the quality of the mixture, apply it to a test surface (for example, scrap of tin). After drying (24 hours), try scraping off the layer with a spatula - if it sticks tightly and does not crumble, the proportions are chosen correctly.

Mistakes when diluting: what impairs the protective properties

Even experienced craftsmen sometimes make mistakes that negate all the advantages of pushsalo. Here are the most common of them:

• 🌡️ Overheating was a problem.

  Heating is higher +50°C destroys corrosion inhibitors. The lubricant loses up to 40% of its protective properties, and cracks may appear on the surface after drying.

• 💧 Using low-quality white spirit.

  Solvent with impurities (for example, technical kerosene) leaves micropores on the metal through which moisture penetrates. Check the quality certificate!

• ⏳ Application on a rusty surface without preparation.

  Pussalo does not remove rust, but only preserves it. Before processing, be sure to clean the metal to "white shine" (use a metal brush or sandblast).

• 🌀 Insufficient mixing.

  If the mixture is not homogenized, there will be thick lumps at the bottom and liquid solvent on top. This leads to uneven protection.

• ☁️ Work in high humidity.

  At humidity levels above 70%, white spirit evaporates more slowly and microbubbles may form in the mixture, which turn into pores after drying.

Another critical error - storage of diluted mixture. White spirit evaporates even in a closed container, changing the proportions. The finished mixture should be used within 24 hours. If long-term storage is required, dilute the pushsalo immediately before use.

What happens if you dilute the pushsalo with gasoline?

Gasoline destroys the paraffin components of the lubricant, which is why the lubricant loses its heat resistance and begins to drain when heated above +30°C. In addition, gasoline leaves a sticky film on the metal, which attracts dust and accelerates corrosion in the long term. In some cases, such a mixture may even dissolve factory primer on the body of the car.

Safety precautions: how to work with fluff and white spirit

Both components belong to flammable substances (hazard class 3 according to GOST 12.1.007-76), therefore compliance with precautionary measures is mandatory. Main risks:

• 🔥 Fire danger. The steam-air mixture of white spirit ignites at a concentration of 1.4–6.0%. Spark sources can be static electricity, open flames or heated surfaces.
• 😷 Toxicity. White spirit vapors irritate the respiratory tract, and prolonged contact with skin causes dermatitis.
• 🌫️ Explosion hazard. When diluting in a closed container, excess pressure may form.

Minimum set of protective equipment:

• 👓 Glasses with side protection (from splashes).
• 🧤 Nitrile gloves (rubber dissolves with white spirit!).
• 😷 Respirator with filter A1 or A2.
• 👕 Cotton clothing (synthetics accumulate static electricity).

⚠️ Attention: If the powder gets on your skin, wash it off warm water and soapand then apply fat cream (for example, "Silicone" or "Protective"). In case of contact with eyes, rinse them 15 minutes running water and consult a doctor.

Should work in well ventilated area or outdoors, away from sources of open flame. If processing is carried out in a garage, use exhaust fan or leave the gate ajar.

Alternative solvents: can white spirit be replaced?

White spirit is not the only solvent compatible with pushsalo. In some cases it can be replaced, but with reservations:

Solvent	Pros	Cons	Recommended proportion
Nefras-S2-80/120 (gasoline galoshes)	Evaporates quickly, cheaper than white spirit	Aggressive to rubber seals, strong odor	85 : 15
Solvent	Dissolves thickeners well, suitable for cleaning	More toxic than white spirit, may leave a film	90 : 10 (for rinsing only!)
Kerosene for lighting	Less volatile, suitable for long-term protection	Takes longer to dry, may leave greasy stains	70 : 30
Solvent 646	Fast evaporation, suitable for spraying	Contains acetone, which destroys fluff at concentrations >10%	95 : 5

⚠️ Attention: Replacing white spirit with acetone, toluene or methyl ethyl ketone unacceptable! These solvents destroy the paraffin base of the pushsalo, turning it into a shapeless mass without protective properties.

If you must use an alternative solvent, test the mixture on a small area of metal first. After drying, check:

• 🔍 No cracks or peeling.
• 💧 Water-repellent properties (drop water - it should roll off).
• 🔥 Heat resistance (check with a hairdryer when +50°C).

FAQ: Frequently asked questions about diluting pushsalo

Is it possible to dilute pushsalo with diesel fuel?

Technically possible, but not recommended. Diesel fuel (especially summer fuel) contains sulfur compounds that accelerate metal corrosion. If there is no alternative, use winter diesel fuel in proportion 90 : 10 and only for short-term protection (up to 6 months).

How long does it take for diluted pushsalo to dry?

Drying time depends on proportions and conditions:

• 🌞 When +20°C and humidity up to 60%: 70 : 30 — 6–8 hours, 80 : 20 — 12–16 hours, 90 : 10 - 24 hours.
• 🌡️ When +5°C time increases by 2–3 times.
• 💨 Forced drying (fan) reduces the time by 30%, but can lead to cracking of the layer.

Complete polymerization takes up to 72 hours.

How to remove dried fluff from the body?

To remove use:

1. Mechanical method: plastic spatula + metal brush (for a thick layer).
2. Chemical method:
   • 🧴 White spirit or nefras - for a fresh layer (up to 1 month).
   • 🧪 Special washes (for example, "Abro PR-600") - for the old pushsalo.
   • 🔥 Steam generator — softens the grease for easy removal.

⚠️ Do not use acetone or gasoline - they can damage the paintwork!

Can diluted pushsal be applied to painted surfaces?

Yes, but with reservations:

• ✅ Suitable for primed or powder-coated surfaces.
• ❌ Do not apply to acrylic or nitro enamels - White spirit may cause clouding.
• 🔍 Pre-check on a small area: if after 24 hours the color has not changed, you can treat the entire surface.

For painted parts it is better to use the ratio 85 : 15 and apply in a thin layer.

How to store diluted pushsalo?

Store the finished mixture in:

• 🏺 Airtight glass or metal container (plastic may dissolve).
• 🌡️ Cool place (+5...+15°C, but not in the refrigerator!).
• 🕒 No longer 24 hours - after this, the proportions are violated due to the evaporation of the solvent.

For long-term storage, dilute the push salo immediately before use.
