Material Showdown: 304 vs 430 Stainless

Property 304 430
Nickel Content 8-10.5% 0%
Salt Resistance Excellent Poor
Price Point $$$ $

5-Step Defense Protocol

  1. Use volcanic rock base layer (2-3cm depth)
  2. Apply marine-grade wax every 90 days
  3. Install stainless steel flowerpot thermal pads in winter
  4. Rotate 45° weekly for even sun exposure
  5. Deep-clean with citric acid monthly

⚠️ Critical Mistake Alert!

Never use table salt for ice removal – it creates micro-cracks. Instead, try crushed walnut shells as eco-friendly traction material.

Seasonal Maintenance Checklist

  • ☑️ Spring: Check weld seams for salt residue
  • ☑️ Summer: Apply UV-protective coating
  • ☑️ Fall: Clear leaf acid buildup
  • ☑️ Winter: Insulate bottom with cork mat
