Taking care of the siding on your home can save you the expense of major repairs, or having to replace the siding entirely due to neglect. A few things you can do to ensure your home’s siding looks great and works efficiently are: Clean your siding with soap, water and trisodium phosphate (you should be able to find this chemical at your local hardware store). Use a soft bristled brush to clean off bird droppings, mildew, and hardened mud. You can also use bleach and water for harder-to-clean mildew stains. Be sure to check your siding for any cracks or damage; If you spot something that looks like it needs repair, act fast before it turns into a larger problem. More here
