ChemDry® Lemon Grove Carpet Deodoriser 4 "sherbet lemons" Adele 28 May 2012 Bought this product out of curiosity, didn't need to mask any smells, but with pets in the house, wanted to give my carpets a freshen up. I knew my carpets were clean as i'd shampooed my carpets. This product treated a large lounge 26'x14' and a large dining room too. The sherbet lemon smell lasted 3 days, fading each day. I would purchase again, but not too often at £7.99.
