(Note the same material-CAB- and instructions apply to the Yellow/amber translucent handle tools made by Xcelite that were really popular back in the day. LC)
Those Craftsman acetate-handle screwdrivers (clear with red flutes/stripes) are made from cellulose acetate butyrate (CAB). Over time they can:
The hazing is usually one of two things:
The good news: mild to moderate haze can often be improved.
Step 1 – Clean First (don’t skip this)
Try the least aggressive method first.
If still hazy:
⚠ Avoid acetone, lacquer thinner, MEK — they will permanently damage the plastic.
Step 2 – Polish the Surface (Most Effective Fix)
If haze remains, it’s usually surface oxidation. Option A – Plastic Polish (Best Method)
Use:
Rub with a microfiber cloth for several minutes.
Buff clean.
This often restores 80–95% clarity.
Option B – Wet Sand + Polish (For Heavy Haze)
If they’re badly cloudy:
This removes the oxidized outer layer and restores transparency.
Do NOT sand aggressively — the handles are not very thick.
Step 3 – Restore Gloss
After polishing:
This improves clarity and slows future oxidation.
What You Cannot Fix
If you see:
That’s internal polymer degradation. Polishing won’t fix it.
Why This Happens
Cellulose acetate:
That’s why some stay crystal clear and others haze badly.

(Note the same material-CAB- and instructions apply to the Yellow/amber translucent handle tools made by Xcelite that were really popular back in the day. LC)
Those Craftsman acetate-handle screwdrivers (clear with red flutes/stripes) are made from cellulose acetate butyrate (CAB). Over time they can:
- Turn hazy or cloudy
- Develop a whitish “fuzzy” bloom
- Feel slightly rough
- Sometimes shrink or crack (more serious aging)
The hazing is usually one of two things:
- Surface oxidation / micro-crazing
- Plasticizer migration (“bloom”)
The good news: mild to moderate haze can often be improved.
Step 1 – Clean First (don’t skip this)
Try the least aggressive method first.
- Wash with warm water + dish soap
- Scrub gently with a soft toothbrush
- Dry completely
If still hazy:
- Wipe with isopropyl alcohol (70–90%)
- Or a light wipe with naphtha (lighter fluid)
⚠ Avoid acetone, lacquer thinner, MEK — they will permanently damage the plastic.
Step 2 – Polish the Surface (Most Effective Fix)
If haze remains, it’s usually surface oxidation. Option A – Plastic Polish (Best Method)
Use:
- Novus #2 Plastic Polish
- Meguiar’s PlastX
- Or automotive headlight polish
Rub with a microfiber cloth for several minutes.
Buff clean.
This often restores 80–95% clarity.
Option B – Wet Sand + Polish (For Heavy Haze)
If they’re badly cloudy:
- Wet sand lightly:
- 1000 grit
- 1500 grit
- 2000 grit
- Then polish with plastic polish
This removes the oxidized outer layer and restores transparency.
Do NOT sand aggressively — the handles are not very thick.
Step 3 – Restore Gloss
After polishing:
- Apply a thin coat of paste wax or car wax
- Buff lightly
This improves clarity and slows future oxidation.
What You Cannot Fix
If you see:
- Deep internal whitening
- Cracks inside the handle
- Severe shrinkage pulling away from the shaft
That’s internal polymer degradation. Polishing won’t fix it.
Why This Happens
Cellulose acetate:
- Absorbs moisture
- Releases plasticizers over decades
- Oxidizes under UV light
- Reacts with oils from hands
That’s why some stay crystal clear and others haze badly.
Prevention After Restoration
- Store out of sunlight
- Avoid high humidity
- Light wax coat every few years
- Don’t soak in solvents
