Cast iron radiators are a popular choice for heating homes in the winter. But like any other piece of equipment, they need to be cleaned regularly to keep them in good condition. Here are four tips for cleaning cast iron radiators:

  1. Use a degreaser. A degreaser like oven cleaner or 409 will remove built-up grease and grime from the radiator surface. Be sure to rinse off the degreaser thoroughly before using it on other surfaces.
  2. Use a scrub brush. A scrub brush is perfect for cleaning tight spaces and around the edges of the radiator. Be sure to use plenty of water to help loosen any debris.
  3. Use a vacuum cleaner with a hose attachment. If you don’t have access to a degreaser or scrub brush, you can use a vacuum cleaner with a hose attachment to clean the radiator surface. Be sure to use caution when using this method, as it can be dangerous if debris gets into the fan motor or ducts on the unit.
  4. Apply an oil-based coating protector once per year if you don’t plan on cleaning your radiator regularly (or if you just want to prolong its life). An oil-based coating protector like Armor All will help prevent rust and corrosion from forming on the radiator surface ..
