Are Grant’s Microfiber Towels Safe on Black Paint?
Grant’s microfiber towels from Harbor Freight are cheap, easy to find, and wildly popular with beginners. But are they actually safe on black paint, the softest and most scratch-prone color? We put Grant’s towels through a full paint-safety torture test to find out.
Estimated Reading Time: 12 minutes
30-Second Verdict
No — Grant’s microfiber towels are not safe for black paint. They are low GSM, have stiff fibers, and use a stitched edge that creates micro-marring, especially on soft or dark paint.
They’re great as interior towels, jamb towels, or wheel towels — but not as paint-contact towels.
If you want swirl-free black paint:
Use Softer Than Soft Towels or Everyday Microfiber Towels.

Introduction: Why Black Paint Exposes Every Flaw
Black paint is beautiful — but it’s also extremely unforgiving. Even the slightest drag, lint, or micro-friction will show instantly under direct sunlight.
This is why the quality of your microfiber towel matters more on black paint than any other color.
Grant’s towels are budget-friendly and useful, but they simply aren’t engineered for delicate or dark paintwork.
1. Fiber Quality Test: Why Grant’s Towels Scratch Black Paint
Grant’s towels use short, stiff fibers that feel “grabby” on soft paint. Under magnification, these fibers have rougher edges than premium microfiber.
The problems:
- Low GSM → less cushion between dirt and paint
- Stiff fibers → increased drag
- Less splitting → less softness
- Cheaper polyester blend → less refinement
On black paint, this combo creates micro-marring very quickly.
2. GSM Comparison: Why Cheap Towels Struggle on Black Paint
GSM = grams per square meter → a measurement of towel thickness & plushness.
Black paint prefers:
- High GSM (320–550 GSM)
- Edgeless
- Very soft, long pile microfiber
Grant’s towels are around **200–250 GSM**, which is simply too thin.
| Towel Type | GSM | Safe for Black Paint? |
|---|---|---|
| Grant’s Towels | 200–250 | No |
| Everyday Microfiber Towels | 320 | Yes |
| Softer Than Soft Towels | 550 | Best |
Low GSM = low safety on black paint.
3. Edge Safety Test: The Stitched Edge Is the Real Danger
Grant’s towels use a traditional stitched edge — a known scratch risk on delicate paint. Even when the fibers soften, the edge remains firm.
Under testing, the stitched edge caused:
- Linear micro-scratches
- Drag marks
- Edge-induced swirls
- Visible marring under sun
4. Linting Test: Cheap Towels Leave Fuzz on Black Paint
Black paint makes lint extremely visible. After several washes, Grant’s towels begin to:
- Lint heavily
- Shed fibers
- Leave residue behind
- Trap dirt inside the low pile
This makes every wipe riskier.
5. Drag Test: How Grant’s Towels Actually Feel on Black Paint
We tested Grant’s towels on a polished black test panel using lubrication spray.
Results:
- Noticeable drag, even when freshly washed
- Micro-marring visible immediately under LED light
- Stitched edges caught on the paint
- Fuzz buildup after 2–3 wipes
Premium edgeless towels glide; cheap towels fight you.

| Fiber Softness | Low–Medium | High |
