Mild steel wall art in Indian weather — how to hang it and keep it looking sharp indoors.
Hang for masonry
Plan for concrete and brick. Use anchors suited to masonry, not drywall-only plugs.
Day-to-day care
Soft dry dust first. Use a damp wipe only if needed, then dry fully. Skip abrasives and harsh solvents on powder coat.
Monsoon and coastal homes
Treat powder-coated mild steel as indoor-default in humid climates. Wipe condensation if the piece sits near windows.
