Mr. Bob Edwards from A.L. Wilson Chemical explains how to remove a remaining stain with a bleach. In part 5, he wraps up this series by going over bleaching tips.
A. Oxidizing Agents
- Sodium Perborate. Alkali + RiteGo. Neutralize (sour) with Acetic acid.
- Sodium per carbonate. Alkali + RiteGo. Neutralize with Acetic acid.
- Hydrogen Peroxide. Neutral. + RiteGo. Accelerate with Ammonia. Flush
- Sodium hypochlorite. Alkali. Neutralize with DroGo B.
- Potassium Permanganate. Acid. Neutralize with Reducing Agents and hydrogen peroxide.
B. Reducing Agents
- Sodium Bisulfite / metabisulfite (ColorGo). + RiteGo. Acid. Accelerated with RustGo
- Sodium hydrosulfite (DroGo B). + RiteGo. Acid. Accelerated with RustGo
- Titanium Stripper (YellowGo). Acid + RustGo.
C. Control of bleaches
- Temperature + or –
- Soak time, or application time + or -.
D. Bleaching Tips
- Gloves and eye protection
- No metallic fibers.
- Every 15 degrees in soak temperature doubles bleaching power.
- Remove stain ingredients first.
- In a soak, keep garments covered with Terry cloth
- In a soak, move garments around periodically.
- With base colored garments test first, and when soaking, do not walk away and forget the soak.
- Never mix bleaches, flush thoroughly.
- Use reducing bleaches first, especially with dyes and ink.
- On residual tannin stains use oxygen bleaches … peroxide, perborate or per carbonate.
- Oxidized oil stains use PermaGo. (Potassium Permanganate)
- To brighten colors, use hydrogen peroxide or sodium Perborate.
- To whiten garments oxidized over time use DroGo B (Hydrosulfite based product.)
- Do not use potassium Permanganate or Chlorine bleach on wool or silk.
- Use hydrogen peroxide on wools or silk because of it neutral to acidic chemistry.
