Air-fresheners
Personally, I miss the fresh 'Pine' fragrance that used to be available in the 'drop-in-the bag' rod format (similar to the Sebo ones) - I think Betterware sold the pine ones through their door-to-door catalogues.
I'm not terribly fond of the lemony smells that many air-fresheners have these days, but I liked the various Hoover brand disk air fresheners. I often wondered if Airwick made them for Hoover, as they reminded me of the disk in the 1970's Airwick Ball air-freshener.
