How to Choose the Right Clay Mitt Grade (Fine / Medium / Heavy)

Every clay mitt comes in three grades：

1️⃣ Fine
2️⃣ Medium
3️⃣ Heavy

But beginners always ask：

“Which one should I buy?”

The answer depends on：

• paint softness

• contamination level

• user skill

• safety priority

Let’s break it down clearly.

What “Grade” Actually Means

Grade = abrasiveness

So:

• Fine → very gentle

• Medium → balanced

• Heavy → very aggressive

Think of it like sandpaper:

• fine → polishing

• medium → correction

• heavy → restoration

Fine Grade — Best for Safe, Daily Use

Uses:

• new cars

• soft paint (Toyota, Mazda, Honda)

• ceramic coating

• DIY beginners

Advantages：

✅ extremely safe
✅ very low scratch risk
✅ great gloss

Disadvantages：

❌ cannot remove extremely heavy contamination

Recommended users：

• beginners

• cars with ceramic

• soft paint owners

Medium Grade — Best Overall Choice

Uses:

• normal contamination

• daily drivers

• normal environmental fallout

Advantages：

✅ strong enough
✅ still safe
✅ balanced performance

This is the MOST POPULAR grade.

Recommendation：

If you only buy ONE mitt → choose medium.

Heavy Grade — Only When Necessary

Uses:

• industrial fallout

• heavy rail dust

• old paint contamination

• overspray

• tree sap stains

Advantages：

✅ strongest removal power

Disadvantages：

❌ highest scratch risk
❌ not beginner-friendly

Only use when:

• contamination cannot be removed by medium

• you have experience

• you use extremely good lubrication

Which Grade for Which Paint?

Can You Use Heavy Grade on Soft Paint?

❌ NO
→ Swirl marks guaranteed.

What If You Choose Wrong Grade?

Too Fine

→ contamination stays
→ surface not smooth
→ must repeat processing

Too Heavy

→ permanent scratches
→ swirl marks
→ clear coat damage

So always start from:

Fine → Medium → Heavy

Never jump to heavy.

FAQs

❓ Can I use medium on ceramic?

Yes — but fine is safer.

❓ Does grade affect price?

Slightly — heavy usually more expensive due to material density.

❓ Can I polish out scratches?

Yes — but safer to avoid them.

Conclusion

The safest rule：

Always choose the least abrasive grade that gets the job done.

Summary：

• Fine → safe / new / ceramic / soft paint

• Medium → most cars / best value

• Heavy → professionals / extreme contamination

Correct grade = safe paint + faster results + better gloss.
