How to Restore Cast Iron Sink
There are many things to consider when undertaking this type of task. You’ll often find that restoring an old cast iron sink is more trouble than it’s worth.
You will be required to shop for some tools and detergents. You need a pocket-size brush and baking soda. It would help if sandpaper, metal polish, paintbrush, cloth pieces, razor blades, and water. You can purchase sandpaper of varying grits or textures, depending on how rusty or smooth your sink surface is. Here are some tips to follow when you’re looking to restore your cast iron sink.
Step 1: Remove the Sink
To pull off the sink, use a pair of channel locks and unscrew the pipe connecting to the wall. If you don’t own a pair of channel locks, then purchase one that comes with multiple head attachments. After turning off the water supply, drain out all water from your sink if you can access it and clean up any rust or old caulk that’s left behind.
Step 2: Wash with Water
Wash the sink thoroughly with water while scrubbing it. You can use a pumice stone to rub out any rust stains and remove the rust. This step is significant because any remaining dirt and rust will cause new rust to form when you apply the new finish. Cast iron sinks are hardy and durable, but they are also vulnerable to stains, scratches, and rust.
You want to make sure that you remove as much of the dirt as possible. If there is any rust on the sink, you need to be especially careful. You may have inherited or purchased a cast iron sink that has been abused over the years. If it is rusty, the first thing to do is to wash it with soap and water. Use mild dishwashing soap and warm water. Wipe it dry after you rinse it off.
Step 3: Fill in pits and smooth rough spots.
Cast iron sink restoration is a rewarding way to spend time in antiques, plumbing, or restoring vintage items. If your cast iron sink is pitted or corroded, you can fill in pits and smooth rough spots with fine-grit sandpaper. Rewash the sink to remove all traces of dust, then dry.
You can fill in small pits and corrosion by dipping a small sponge into a mixture of equal parts of vinegar and water. Then scrub the pitting or corroded areas vigorously with the sponge. The acid in the vinegar will dissolve rust and etch the metal, which will bond to itself as it dries.
Step 4: Remove Stubborn Stain
If you have stubborn stains that won’t come off, you can use a mixture of one-part muriatic acid and five parts water. Just add the acid to the water slowly, making sure not to splash any of it on yourself or your clothes.
Protect it with rubber gloves and eye protection when working with this mixture if you have sensitive skin. After you’ve completed the restoration process, be sure to rinse all of the acid solutions out of your sink thoroughly before using it again.
Step 5: Repair Pinholes in The Sink
You do not need any technical knowledge or skills to repair a cast iron sink, just attention to some basic rules. If your sink has a lot of pinholes, this would mean that you have rust going through to the inside of your sink.
If this is the case, you need to scrub down all holes to free them from rust and dirt. You need to mix vinegar and water in a bowl and apply it to each spot with a Q-tip or an old toothbrush. Let the mixture soak in there for about half an hour.
Step 6: Apply Paint or Sealant
Paint and sealant are the recommended methods to repair damaged cast iron sinks. To restore a cast iron sink with sealant, use a product specifically designed for cast iron sinks, such as Krylon Cast Iron Re-Creation Paint. This type of paint comes with an application brush and is easy to use on new and old sinks.
The paint and sealants used on cast iron sinks depend on how much structural damage the sink has sustained. You must apply paint and sealant. You must also apply paint and glue quickly to prevent rusting from continuing.
