Methylated spirits, also known as denatured alcohol, are a type of ethanol (alcohol) that has been treated with additives to make it unfit for human consumption. The term “methylated” comes from the fact that methanol, a toxic form of alcohol, is often one of the key additives used. This simple product has a variety of uses in household, industrial, and personal care settings.
In this article, we’ll cover what methylated spirits are, their common uses, safety precautions to take when handling them, and their potential benefits.
What Are Methylated Spirits
Methylated spirits are essentially ethanol with added substances—usually methanol or other bittering agents—to discourage ingestion. The added chemicals make it undrinkable, and this is why it’s also called denatured alcohol. In some countries, dyes are also added to give it a distinct color, typically purple or blue, so that it is easily distinguishable from drinkable alcohol.
The purpose of methylating ethanol is to avoid the taxes and regulations associated with the sale of consumable alcohol while still allowing it to be used for a wide range of practical purposes.
Common Uses of Methylated Spirits
Methylated spirits are incredibly versatile and have a range of applications in both household and industrial settings. Here are some of the most common ways methylated spirits are used:
Cleaning Agent
Methylated spirits are often used as a powerful cleaning agent. They can be applied to surfaces to disinfect and remove dirt, grease, and grime. This makes them ideal for cleaning windows, glass, mirrors, and stainless steel. Additionally, they evaporate quickly, leaving no residue behind, which is perfect for streak-free cleaning.
Paint Thinner and Remover
One of the most common uses for methylated spirits is as a solvent for thinning paints and removing paint spills. Its solvent properties make it effective for breaking down the compounds in oil-based paints and varnishes, making it easier to clean brushes and other painting tools.
Fuel for Camping Stoves
Methylated spirits are often used as a fuel source for small camping stoves. Their high ethanol content makes them an efficient and clean-burning fuel, ideal for cooking outdoors. The alcohol burns at a relatively low temperature, making it a safe option for portable stoves.
Disinfectant
Because of its high alcohol content, methylated spirits are commonly used as a disinfectant. They are effective at killing germs and bacteria, which is why they are often used in medical and household cleaning applications.
Woodworking and Furniture Restoration
Methylated spirits are often used in woodworking and furniture restoration to strip old varnish or polish from wooden surfaces. They are effective at dissolving old finishes and preparing the wood for refinishing. Additionally, they can be used to clean wood and remove any stains or sticky residues.
Degreaser for Tools and Machinery
Methylated spirits are great for cleaning and degreasing metal surfaces, tools, and machinery. They are highly effective at breaking down oils, grease, and other residues that build up over time, making them a go-to choice for cleaning in industrial and automotive settings.
Hand Sanitizer Ingredient
In some cases, methylated spirits are used as an ingredient in hand sanitizers due to their ability to kill bacteria and viruses. However, because of the added chemicals that make the spirits undrinkable, this use is less common in commercial hand sanitizers and more likely in homemade or industrial-grade versions.
Safety Precautions When Using Methylated Spirits
While methylated spirits are a useful and versatile product, they can be hazardous if not handled correctly. The added methanol and other chemicals make them toxic if ingested, inhaled, or absorbed through the skin. Here are some key safety precautions to follow when using methylated spirits:
Avoid Ingestion
Methylated spirits are toxic and should never be ingested. Ingesting even small amounts of methylated spirits can lead to alcohol poisoning, blindness, or even death. Always keep them out of reach of children and store them in clearly labeled containers.
Use in a Well-Ventilated Area
The fumes from methylated spirits can be harmful if inhaled in large quantities. When using methylated spirits for cleaning, painting, or as a fuel source, make sure you are in a well-ventilated area. If you’re working indoors, open windows and doors to allow fresh air to circulate.
Wear Protective Gear
If you’re using methylated spirits for tasks like paint stripping or degreasing, it’s a good idea to wear protective gloves to avoid prolonged skin contact. If there’s a risk of splashing, wear protective eyewear as well. The alcohol and other additives can be irritating to the skin and eyes.
Keep Away from Heat and Flames
Methylated spirits are highly flammable. When using them as a cleaning agent or solvent, be sure to keep them away from open flames, heat sources, and sparks. If using them as a fuel source, handle them with care and always follow the manufacturer’s guidelines for safe usage.
Store Properly
Store methylated spirits in a cool, dry place, away from direct sunlight and heat. Always keep the container tightly sealed when not in use to prevent evaporation and accidental spillage.
Benefits of Using Methyl’ated Spirits
Despite the need for caution, methyl’ated spirits offer several advantages over other cleaning products, solvents, and fuels.
Versatility
One of the main benefits of methyl’ated spirits is their versatility. From household cleaning to industrial uses, methyl’ated spirits can handle a wide variety of tasks. Their ability to dissolve oils, greases, and adhesives makes them a go-to choice for many different applications.
Cost-Effective
Methyl’ated spirits are often more affordable than specialized cleaning products, paint thinners, or disinfectants. Because they can be used for so many different purposes, they also reduce the need to purchase multiple products.
Eco-Friendly
Compared to some synthetic solvents and cleaners, methyl’ated spirits are considered a more environmentally friendly option. Because they are alcohol-based, they evaporate quickly and don’t leave harmful residues behind. Additionally, ethanol is a renewable resource, further adding to their eco-friendly credentials.
Effective Disinfectant
With a high ethanol content, methyl’ated spirits are an effective disinfectant for surfaces, tools, and other items. They can help kill bacteria, viruses, and fungi, making them useful for sanitizing in both household and industrial settings.
Quick Evaporation
Methyl’ated spirits evaporate quickly without leaving streaks or residues behind. This makes them ideal for cleaning surfaces like glass or stainless steel, where a clean, streak-free finish is important.
Conclusion
Methyl’ated spirits are a valuable and versatile product that can be used for cleaning, disinfecting, thinning paints, and even as a fuel source. While they are highly effective for these tasks, it’s crucial to handle them with care and follow safety guidelines due to their toxic and flammable nature.
Whether you’re using them to clean your windows, strip paint, or fuel your camping stove, methylated spirits offer a cost-effective and environmentally friendly solution. Just remember to store them properly and always use them in a well-ventilated area.
