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.).
Most companies cover a standard number of vents and add an extra fee if your house has additional vents, typically $20-$35. Most standard prices cover 20-30 vents in a 1,500 square foot home. Duct cleaning is also a good time for dryer vent cleaning service, which typically costs $120-$200.
