Why Proper Cleaning Matters for 430 NO.4 Stainless Steel Plate

The NO.4 finish on 430 stainless steel is created by directional brushing with 150–320 grit abrasives, producing a fine satin texture that beautifully hides fingerprints and minor scratches. However, the brushed lines can trap dust, grease, and fingerprints if not cleaned regularly. Proper cleaning preserves the elegant appearance, prevents surface dulling, and maintains the excellent corrosion resistance of the 16–18% chromium alloy.

Recommended Daily and Weekly Cleaning Routine

Daily cleaning (most common for high-touch areas)

1. Wipe with a soft microfiber cloth slightly dampened with warm water.
2. For light fingerprints or marks, use a 1:10 solution of mild dish soap and warm water.
3. Wipe in the direction of the brush lines (never across) to avoid creating new swirl marks.
4. Dry immediately with a clean, dry microfiber cloth to prevent water spots.

Weekly deep cleaning

1. Apply a small amount of stainless steel cleaner formulated for brushed finishes (e.g., 3M Stainless Steel Cleaner or Weiman Stainless Steel Cleaner & Polish).
2. Spray lightly and wipe gently along the grain with a soft cloth.
3. Rinse with clean water if the product requires it.
4. Buff dry for a renewed satin sheen.

DOs and DON’Ts for Cleaning 430 NO.4

For Chinese-standard projects, the identical material is also available under GB/T 10Cr17 1Cr17 stainless steel sheet.

Chemical Composition & Why It Affects Cleaning

The chemical composition of 430 NO.4 remains the same as standard 430:

The high chromium content provides natural corrosion resistance, so aggressive cleaners are unnecessary and can actually damage the passive layer.

Mechanical & Surface Properties That Influence Cleaning

The satin texture makes cleaning easier than mirror BA because marks are less visible, but you must always follow the grain direction.

For Japanese-standard requirements, please see our JIS G4305 SUS 430 stainless steel sheet.

Long-Term Maintenance Tips

• Apply a light coat of stainless steel protectant spray (oil-free) every 3–6 months to reduce fingerprint attraction.
• For outdoor architectural use, rinse with clean water every 3 months to remove airborne contaminants.
• Avoid contact with chlorine-based cleaners, hydrochloric acid, or ferric chloride.
• In food-processing environments, use only NSF-approved or food-grade neutral cleaners.
