1 Prepare safe work
Photograph the item, check its stability and value, and first test the process on a hidden spot. Work with ventilation, gloves, and eye and breathing protection.
⚠ Warning: Old finishes can contain lead, and a valuable antique can lose value through unskilled cleaning. Have an unknown finish and serious structural damage assessed by a restorer first.
2 Determine the condition and cause
Check the load-bearing joints, welds, and legs. Deep corrosion, a crack, or a thinned tube require repair before cosmetic work.
3 Perform the key check
Use a wire brush and sandpaper to remove loose rust and paint down to a solid base, then degrease and dry completely.
4 Do the repair or maintenance
Apply an anti-corrosion primer and thin coats of exterior paint, respecting the drying time between coats and curing before use.
? Tip: Photograph the initial condition and change only one thing at a time. That makes it easier to tell what actually solved the problem.
5 Test the result
Let the glue, coating, or finish dry completely according to the manufacturer, then gradually load the item and inspect the joints in good light.
