Green Cleaning Recipes

 

Use a garbage disposal sparingly; always put fats, oils, and grease into the garbage

What about food waste, sinks and garbage disposals? Garbage disposals connect to the sewer system and food waste will be treated and recycled through the wastewater treatment plants as biosolids soil amendment. However, small particles of food can stick to sewer pipes and cause clogs and maintenance problems.

What about fats and grease? Fats, oils, and grease are things that should never go down the drain. These things may be liquid to begin with (think bacon) but it will harden on the sides of pipes which will eventually cause blockages and can lead to expensive plumbing repairs.

Helpful hints:

1) Use an empty tin can or glass jar to store fats and grease- leave can on the counter or store in the freezer.

2) Throw hardened grease in a garbage can or recycle at a biodiesel recycling facility when possible.

3) Scrape plates, pots, pans before washing- makes dishwashing easier and keeps pipes clean.

4) Use a drain screen in your kitchen (and in the bathroom for hair)- empty weekly into the garbage can.

5) Clean drains monthly with baking soda and vinegar to keep pipes clean, or pour boiling water down drains .
