I'm in a vacation home and have encountered my first gas-operated dryer. The owner of the home told me to clean out the lint each time or the dryer was likely to catch fire. I'm cleaning out the lint each time after drying anyway but the words "catching fire" scared the hell out of me. (Fire's probably my biggest fear) So, does anyone have experience with these kind of dryers? Are they generally safe to use or do they really catch fire rather easily? Thanks!
