summary: This note details how to create an enhanced rust removal soak by adding specific
|
||||
chemical boosters (sodium gluconate, ascorbic acid, triethanolamine, isopropyl alcohol,
|
||||
and heat) to a basic chelator solution (EDTA, citrate) to improve rust penetration,
|
||||
prevent redeposition, speed up reaction, inhibit flash rust, and increase effectiveness.
|
||||
The key optimized "Pro" formula combines 1L water with 50g EDTA, 30g sodium citrate,
|
||||
10g sodium gluconate, 5g ascorbic acid, and a drop of dish soap for superior rust
|
||||
removal.

title: Derusting Solution
|
||||
---
|
||||
|
||||
1 liter water
|
||||
100 g citric acid
|
||||
40 g washing soda or 63 g baking soda
|
||||
|
||||
To turn your soak into a professional-grade "super chelator," you can add specific boosters that improve penetration, speed up the chemical reaction, or prevent the solution from getting "tired."
|
||||
|
||||
1. Sodium Gluconate (The Synergy Booster)
|
||||
|
||||
Adding **Sodium Gluconate** creates a "triple-threat" chelating system. While EDTA and Citrate work at neutral pH, Gluconate is exceptionally effective at holding iron in solution even as the pH fluctuates. This prevents the rust you just dissolved from "re-depositing" back onto the part.
|
||||
|
||||
- **Amount:** 10–20g per liter.
|
||||
|
||||
2. Ascorbic Acid (The "Iron Reducer")
|
||||
|
||||
Rust is Iron(III), which is hard to dissolve. **Ascorbic Acid (Vitamin C)** acts as a reducing agent that converts Iron(III) into Iron(II). Iron(II) is much more soluble and "pre-chelated," making it significantly easier for your EDTA and Citrate to grab and pull away.
|
||||
|
||||
- **Note:** This will lower the pH, so you may need to add a pinch of baking soda to bring it back to neutral.
|
||||
|
||||
3. Triethanolamine (TEA) (The Corrosion Guard)
|
||||
|
||||
TEA is a common additive in industrial rust removers like Evapo-Rust. It serves two purposes:
|
||||
|
||||
- **pH Stabilizer:** It keeps the solution alkaline (around pH 8–9), where EDTA is most powerful.
|
||||
- **Flash Rust Inhibitor:** It leaves a microscopic film on the metal that prevents it from rusting the second you take it out of the bath.
|
||||
- **Amount:** 1–2% of the total volume.
|
||||
|
||||
4. Isopropyl Alcohol (The Penetrant)
|
||||
|
||||
If your item has tight crevices, bolts, or textured surfaces, adding a small amount of **70% or 91% Isopropyl Alcohol** lowers the surface tension of the water even further than soap alone. This allows the chelators to "wick" into microscopic cracks where rust is hiding.
|
||||
|
||||
- **Amount:** 5% of your total liquid volume.
|
||||
|
||||
5. Heat (The Speed Multiplier)
|
||||
|
||||
While not a chemical additive, **temperature** is the single most effective way to boost this mixture.
|
||||
|
||||
- Raising the temperature to **120°F–140°F (50°C–60°C)** can make the chelation process happen **2 to 4 times faster**. Use a cheap "crock pot" or a sous-vide immersion circulator to keep the bath warm.
|
||||
|
||||
Summary "Pro" Formula:
|
||||
|
||||
- **1L Water** (Distilled is best)
|
||||
- **50g EDTA** (Chelator)
|
||||
- **30g Sodium Citrate** (Chelator/Buffer)
|
||||
- **10g Sodium Gluconate** (Synergy)
|
||||
- **5g Ascorbic Acid** (Reductant)
|
||||
- **1 drop Dish Soap** (Surfactant)
|
||||
|
||||
|
||||

### Full Suggested Final Concentrations for 1 L Soak
|
||||
|
||||
These are practical, balanced starting points based on your ingredients (scale/test and adjust pH to ~5–7.5 for best chelation + reduction). Total actives stay moderate (~10–20%) to avoid saturation issues.
|
||||
|
||||
- **Ascorbic acid**: 30–50 g (3–5%) — reduction of rust (Fe³⁺ → Fe²⁺).
|
||||
- **Sodium citrate** (trisodium, anhydrous or adjust for dihydrate): 20–40 g (2–4%) — chelation + buffering.
|
||||
- **Sodium gluconate** (or potassium if swapping): 20–50 g (2–5%) — strong iron chelation.
|
||||
- **EDTA** (disodium or tetrasodium): 10–25 g (1–2.5%) — broad heavy metal chelation.
|
||||
- **TEA** (triethanolamine): 10–20 g (1–2%) — pH buffer to ~6–7.5; add gradually while checking pH.
|
||||
- **Surfactant** (e.g., coco glucoside, decyl glucoside, or mild dish soap): 1–5 mL (0.1–0.5%) — wetting/penetration.
|
||||
- **Sodium silicate 40% solution**: **10–15 mL** (≈4–6 g active silicate) — corrosion inhibition + mild builder.
|
||||
- **Water**: Balance to 1 L (use distilled/deionized if possible to minimize hard-water interference in LA).
|
||||
- **Optional natural colorant** (from earlier): 0.1–0.5 g turmeric/curcumin extract or similar for subtle yellow tint.
|
||||
|
||||
### Mixing and Usage Notes
|
||||
|
||||
1. Dissolve solids in warm water (~40–50°C) first: ascorbic → citrate/gluconate/EDTA → TEA (slowly, monitor pH rise) → surfactant.
|
||||
2. Add sodium silicate 40% last (it's alkaline) — stir well; it may slightly thicken or cloud temporarily but should clear.
|
||||
3. Check/adjust final pH (strips or meter) to 5.5–7.5. If too high (TEA + silicate), add a bit more ascorbic acid; if too low, more TEA.
|
||||
4. Soak rusty tools 4–48 hours at room temp (or warm to 40–60°C for faster action). Agitate occasionally.
|
||||
5. Post-soak: Rinse thoroughly with water, then IPA dip if desired for quick dry/no flash rust, then oil tools.
|
||||
6. **Safety**: Still non-toxic overall (food-grade-ish levels), but wear gloves/eye protection—silicate can be mildly irritating in concentrate. No strong fumes.
|
||||
|
||||
This keeps the soak effective, safe, and greener than acid-based removers. If you notice gelling (rare at these low levels) or slower rust removal, reduce silicate to 5–10 mL. Share your exact amounts of the other ingredients or observed pH if you want more precise tweaks! Test on a scrap tool first.
|
||||
|
||||
### Suggested Concentrate Recipe (for Dilution to 1 L Final Soak)
|
||||
|
||||
Use **250 mL total water** as a safe starting point (4× concentrate). Scale down to 200 mL if you test and it dissolves fully.
|
||||
|
||||
- **Water**: 250 mL (warm to 40–60°C; distilled preferred).
|
||||
- **Ascorbic acid**: 30–50 g — dissolve first (acidic, helps initial mixing).
|
||||
- **Sodium citrate**: 20–40 g.
|
||||
- **Sodium gluconate**: 20–50 g.
|
||||
- **EDTA (disodium or tetrasodium)**: 10–25 g — add slowly after TEA/silicate for better solubility.
|
||||
- **TEA (triethanolamine)**: 10–20 g — add next; raises pH, dramatically improves EDTA dissolution.
|
||||
- **Sodium silicate 40% solution**: 10–15 mL — add near end; provides alkalinity and inhibition.
|
||||
- **Surfactant** (coco glucoside or mild dish soap): 1–5 mL — last.
|
||||
- **Optional colorant**: Dissolve in a bit of the water first.
|
||||
|
||||
**Mixing steps**:
|
||||
|
||||
1. Heat water to 40–60°C.
|
||||
2. Dissolve ascorbic acid fully.
|
||||
3. Add citrate, gluconate → stir until clear.
|
||||
4. Add TEA → pH rises, solution warms/clears more.
|
||||
5. Add EDTA slowly while stirring vigorously (it may clump initially but should dissolve as pH hits ~6–8).
|
||||
6. Add silicate solution → may thicken slightly but should stay fluid.
|
||||
7. Add surfactant and colorant.
|
||||
8. Cool to room temp; check for clarity/no sediment. If thick, add 50–100 mL more water. If crystals form on standing, warm and stir again.
|
||||
|
||||
**Storage**: In a sealed bottle; stable for months if pH ~6–8. Shake before use.
|
||||
|
||||
**Dilution**: Add the entire concentrate to 750–800 mL water (to make 1 L total). Stir well. Final pH should settle ~5.5–7.5—test and adjust if needed (small extra ascorbic for lower, TEA for higher).
|
||||
|
||||
If you go below 200 mL water and hit issues (e.g., paste-like or undissolved EDTA), the fix is usually more water or extra TEA/silicate to boost pH/solubility. Test a small batch first—LA's room temp (~20–25°C) helps, but warm mixing is key.
|
||||
|
||||
If you share your exact target amounts for each ingredient, I can calculate a more precise minimum water volume!
