Baseboard Cleaner! First vacuum around them, then use: 1/4 cup of fabric softener 1 gallon of water A microfiber rag With this method, you can easily clean any leftover dust or grime and repel any future dust since the fabric softener naturally repels static electricity (which attracts dust).
Ammonia for cleaning burners: Put a little ammonia and one of the removable burners in a ziplock bag and leave them overnight. The fumes from the ammonia will loosen the gunk, and you can wipe them down in the morning. I have done this and it works great!
