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.).
Dryer vent ducts should be inspected at least once a year to reduce the risk of fires and carbon monoxide poisoning. If you hire a professional to clean your vent, expect to pay between $75 to $150, depending on the length and location of the vent.
