There's many tutorials on how to remove rust stains from stainless steel sinks out there but none are very detailed. While this tutorial isn't new or original, I thought it might help someone else who is a visual learner like me! Pour some baking soda in a bowl.
1 A proper home air duct cleaning costs anywhere from $400-$1,000, depending on the size of the system to be cleaned, the type of services offered, the regional climate and the level of use the ventilation system gets, the type of materials inside the ductwork and the amount of contaminants (dust, mold, etc.).
Two years ago I had furnace and ducts cleaned at my old house and it was under $400. Now the cost is $700 for this house. I will keep looking for someone to offer a lower price, check them out, and have it done.
