Collect it in an empty can and put it in the trash. These steps will reduce your need for a drain cleaner. Open windows to air out the house occasionally to avoid the use of chemical air fresheners. Use alternative or less toxic, homemade products. One way to get a safer product is to make it yourself.
Homemade products have definite advantages, but they also have disadvantages.
They may take longer to clean effectively. Since they may not be as strong, they may take more time to work. More elbow grease may be required. You may have to scrub harder. They may not clean as well.
