Plastic trash cans are easy to clean and keep odor free, with grocery bags helping to lower trash liner expenses, all this adds up to make this type of trash container one of the more popular ones. By emptying the bag daily, there is no chance of an odor building up. A useful tip is to make sure the trash liner fits the can and is not so small that the bag slides down, allowing food and odor to accumulate throughout the day. Also, hose the trash can down outside on a daily basis if it needs it, while using a sponge with dishwater liquid to clean the stains that remain.
Trash Can Smell Masking : If you can't beat them, hide them; that's the whole idea behind perfumes and some such products, isn't it? The methods below basically mask the smell with another more powerful odor rather than remove the smell, so you should be sure you are going to be happy with the result.
