The term ‘paint stripper’ is just an umbrella term that covers any compound that is designed to remove paints and other adhesive like compounds. Paint strippers themselves come in four different types that you will need to consider when buying. Here is how you can break them down:
Caustic paint strippers are made with active lye as one of the main compounds. This lye (sodium hydroxide) is there to cause a chemical reaction with the paint to help remove it from the metal. This reaction effectively turns the paint into soap, which causes it to slide off. Caustic paint strippers work very well but are very harsh on the skin and eyes and should be handled with care.
Solvent paint strippers are highly chemical compounds that are generally considered a bit more volatile. This is due to their high Volatile Organic Compound (VOC) levels. Solvents use chemical reactions to dissolve and remove paints of all types from virtually every surface. They are extremely versatile, and are favored among professionals. However, they do come with a very pungent odor, are hazardous when breathed in through fumes, and are not very environmentally friendly.
Biochemical paint strippers are preferred by those who want to avoid high levels of VOCs and NMPs. They are made from organic chemical compounds such as terpenes and organic N-methyl-2-pyrrolidone. These are considered a safer alternative to caustic or solvent paint strippers, but do still need to be treated with caution. They are better for the environment though.
VOC-free paint removers work without the presence of NMPs, lye, or other VOC compounds. They typically use naturally occurring compounds such as alcohol, and remove paints such as oil based and water based rather easily. They are odorless, safe for the skin, and safe for the environment. Their only major drawback is that they are not the strongest or most effective against tougher compounds like epoxies or latex paints.
Removing paint from metal does require quite a bit of care and proper preparation. You will need to take the time to understand the paint you are working with, as well as the metal it is painted on. This will help you to get yourself ready to prepare the area for removal of the paint.
Remember that not all paints are the same and not all metals react the same way. If you are working with older pieces of furniture or toys remember to test the paint for lead. This will help you know how to safely and effectively remove the paint. Once you have identified the paint and the metal, as well as purchased the proper paint stripper, you can finally get started.
Ideally you should always remove paint outside if you are using a paint stripper. While some are great for indoors, they are not always ideal for use in enclosed areas whenever it can be helped. Prepare your outdoor area with heavy duty cardboard, and block off any grass or gardening areas that might suffer from the chemical exposure.
Finally, tape off any areas of the surface that you don’t want stripped–if any–and prepare to get to work!
Once you are set up and ready to go, you can apply the paint stripper. Pour the stripper into a metal can, or into your chemical sprayer if being used. If you are using a paint brush to apply the stripper make sure you are using a disposable brush as it might not be usable after.
Apply a thin layer of the stripper to the metal surface and allow it to sit as long as the manufacturer recommends. Don’t touch it or apply more until you have finished the next step!
After the paint stripper has sat and worked its magic, you can now set about removing the paint. This will require you to use a paint scraper or paint scraping pad to gently remove the paint. Slowly chip away at it in a way that doesn’t scrape the metal underneath the surface. Only remove the paint that comes away easily without too much resistance.
If you cannot get all of the paint off in one round, always go back to the previous step and apply another layer of paint stripper. Continue doing this until the paint is all off and the metal is paint-free!
Now that you have removed all of the paint, you can clean off the metal and prepare it for whatever you wish to do with it. To clean the metal, you should wipe it down with mineral spirits to remove any residual paint flakes that may be hanging on. Then you should spray and wipe down the metal with water to remove the residue of the paint stripper.
Once you have fully washed and dried the metal, you can now re-paint it or form it however you want. This process can be done with virtually any metal ranging from copper to aluminum and stainless steel!
You may be into crafting, or you may be interested in repairing or restoring old furniture. Whatever your reasons, when removing paint from metal you need the right stripper to get the job done.

Paint strippers will work over the course of a few minutes to several hours. This will depend on the type of paint stripper you are using and how many layers of paint you are removing. Some fast acting removers can begin working in as fast as 15-30 minutes. However, more heavy duty needs might require the paint stripper to be left on for as long as 24-72 hours. Always follow the instructions for advised setting time before removing from the surface of the metal.
Most modern paint strippers are excellent at removing a whole host of varying paint mixtures from metal. Acrylic, oil based, water based, latex, epoxy based, you name it. These paints can all be removed with the right paint remover and a bit of patience.
Paint strippers are tough compounds that should always be handled with care. Even VOC-Free paint removers should be handled with gloves and goggles at all times. You should also wear a respirator mask to avoid breathing in the fumes. This is primarily for caution, but is always a good practice to have when working with chemicals of any kind.
Applying paint stripper and remover on metal can be done in a variety of ways. The most common method is to use an old or disposable paint brush. This allows you to get an even coat while also reaching any crevices easily. Another method is to use a chemical grade sprayer to apply the paint remover easily and evenly. This of course only works with thinner paint strippers that can be pushed through the spray nozzle.
Most paint removers are perfectly safe to use with metals of all types. Ranging from aluminum to copper and iron. Paint strippers and removers are generally designed to work on metal, wood, ceramic, plastic, glass, etc,.
Paint stripper works the same way on metal as it does on any other surface material. Depending on the type of paint stripper you are using, the paint stripper will loosen or dissolve the paint over time. This reaction will change based on the type of paint and the type of paint stripper being used.
