Q We have a permanently installed gas grill that is about 30 years old. It does not get a lot of use. For a number of years, the interior paint on the lid has had flakes and chips. I scrape it, use a wire brush and steel wool to clean it, and rinse it with water. After a few days of drying, I spray it with black heat-resistant paint.
It looks good for a year or so, then the flaking starts again.
Is there something you can recommend for a cleaner (for the smoke and grease) or primer, or can you tell me what I might be doing wrong so that my attempts at refurbishment will last longer?
A Have you used a degreaser on the interior to prep for painting? Sometimes a buildup of grease will prevent paint from adhering to the interior surface of a grill. Rinsing with water isn't a good substitute.
Some experts recommend several thin coats of heat-resistant paint, with proper drying and light sanding between coats, rather than one thick coat, for a longer-lasting finish.
Once you finish painting and the final coat is dry, turn up the heat full blast to cure the new coating. The experts also suggest a quick touch-up coat periodically, perhaps once a year, whether the grill needs it or not.
Thirty years is a long time for anything to remain fresh and good-looking — people as well as gas grills. The fact that you've kept it running this long is a tribute to your care and diligence.
