Box cutters are very useful cutting tools, which means they are used often and in many conditions. This leads them to get dirty and grimy over time. So how do you clean box cutters? Find out below.
How To Clean Box Cutters
This is what you need to clean box cutters:
- Dish soap
- Hot or warm water
- Solvent (WD40 or mineral spirits)
- Sponge or washcloth
- Wire brush, toothbrush, toothpicks, cotton swabs.
- Dry rag or cloth
Cleaning box cutters is not difficult and only takes a few minutes. Here are the steps:
- Put on rubber dish gloves before cleaning the box cutters.
- Fill up the sink or a small bucket with hot, soapy water. You can use dish soap.
- Clean the box cutters thoroughly. Remove any stains, grime, and dirt with a sponge or rag.
- Disinfect them with a sanitizing solution (see list below).
- Rinse the box cutters in clean, warm water.
- Wipe down the box cutters with a dry cloth and remove any remaining moisture.
Make sure to clean the box cutters with the blade pointed away from you as best you can. Do not wipe the blade too quickly as it could cause it to slip and cutting your finger.
You can use a dishwasher to clean a box cutter also, but it may dull the blade due to the washer’s abrasion.
Always wear rubber gloves when handling cleaning supplies. Also, wipe down the box cutters with a cloth to dry them. Do not heat the box cutters in a fire to remove moisture. This can weaken the steel and cause it to break.
Disinfecting Box Cutters
Box cutters can get bacteria (microbes, viruses, spores) and grime stuck to them, just like other knives. However, unlike kitchen knives, you probably will not be cutting raw meat, poultry or seafood with a box cutter. Nevertheless, disinfecting them helps keep you safe in case you are cut.
Its important to clean and disinfect box cutters, atleast occassionally, but preferably regularly.
To disinfect box cutters, you can use:
- Hot soapy water (dish soap)
- Chlorine bleach
- Isopropyl Alcholol
Follow the same basic steps as cleaning box cutters above. Dip the box cutters in hot soapy water, the bleach, or the alchohol. It may work simply to wipe the blade with a rag dipped in either of these chemicals.
Box Cutters And Alchohol
70% isopropyl alcohol works great to remove difficult grime that the dishsoap fails to remove. Dip paper towel, a cotton swab, or small rag in alchohol and wipe down the entire box cutter. Remove the blade and apply this separately if needed. Wipe down the box cutters with a dry cloth and let air dry.
Alcholol will not hurt the box cutters in any way and can help remove packing tape residue or weak glues.
Box Cutters And Bleach
You can use regular household bleach to decontaminate box cutters.
Just by soaking box cutters or blades for 5 minutes in 40% bleach solution will kill all the bacteria. Mix teaspoon of bleach with 1 quart of water in a food storage container. This should be large enough to totally submerge the box cutters.
You can scrub down the box cutters with a scouring pad, sponge, or wire brush. When finished rinse down the box cutters and dry using a cloth. Let air dry on a paper towel.
Box Cutters And Soap
Box cutters can be cleaned using common dishsoap and warm water. This may not be enough, however, as difficult grime may be stuck on the blade. To remove this, you will need degreaser solvents, alchohol, or bleach.
It is important to clean box cutters because a dirty one is more likely to corrode.
Box Cutters And Rags
Use a rag to wipe away the dirt, dust, and cleaning solution from box cutters, and to dry them. You can also use thick paper towels to do this as well.
Box Cutters And Dust
If your box cutters sit in the garage or any dusty area for long enough, they will acquire dust deposits. Dust can stick to the handle, blade, or any crevices. The dust can also mix to any glue or moisture and become hard and affect the function of the box cutters.
Packages and cardboard boxes may have been sitting in a dusty warehouse before being shipped. There is likely some still on the box when you use the box cutters.
Box Cutters And Dirt
When carrying box cutters with you on jobsites, they can get dirty like other tools. Box cutters with dirt or grime stuck to it may need wiping down or scrubbing with a wire brush prior to cleaning it.
Do not leave dirt on box cutters as the moisture within it can cause them to rust.
Box Cutters And Grime
Grime can be present just about anywhere their is water, dust, oils or greases. Box cutters can easily be covered in small amounts of grime.
To remove grime, simply wiping box cutters or washing it in dishsoap may not be enough. This will require a oil-based solvent, such as goo gone, wd-40, or turpentine.
However, once the grime is removed, be sure to add a drop of oil to the blade because these solvents will remove any beneficial oils you want to keep.
Box Cutters And Glue
Box cutters can get gluey. Adhesive substances can be found on shipping boxes, crates, and packages of all sorts. To remove glue from box cutters, use Acetone, b-12 carbuerator cleaner, or nail polish remover.
