We have a big debate going on in the shop — should we change from degreasing with acetone to alcohol. A bit of research (GOOGLE) found that denatured alcohol would be better because of the zero water content, but how do acetone and alcohol compare, apart from price. And should we be considering anything else? We are mainly welding nickel and the welds looks the same for both.
Would appreciate any insight.

There have been a few big debates here as well, to say the least.
I don’t even want to post a link to the last thread on it.

Re: Acetone vs alcohol for degreasing.
I can’t tell you which is best. I have used both and can’t tell any difference. I can say I would be less afraid to get alcohol on my hands, and the alcohol is one of the best electronic cleansers there is. I have never considered the price as I don’t really need it that much. Most of my welding is on rusty stuff.

Re: Acetone vs alcohol for degreasing.
Unless you believe there is any silcone on the surface of what your cleaning you should be able to get bye with alcohol. I prefer acetone because I know it gets most everything and evaporates quickly. But your right about the price difference.

Re: Acetone vs alcohol for degreasing.
What do you mean «zero water content» for denatured alcohol versus acetone?
Plain acetone really doesn’t have water in it.
Alcohol absorbs moisture from the air, so even if it didn’t have any water in it to start with (100% alcohol), as soon as it is exposed to the air it will have -some- water in it.
And different denaturing additives may be added to the main ethanol base to make the alcohol into «denatured alcohol». Countries may specify what may be used to denature the ethanol, or ‘formulas’ may change, etc, etc. And what formerly worked fine for you may suddenly not work, because the denaturing agent changed in the mix.
Also, there may be environmental issues for industrial use of various solvents that you should check into (if you already haven’t).

Re: Acetone vs alcohol for degreasing.
Sorry to be inaccurate. I meant denatured alcohol contains no water when compared to other alcohols, eg rubbing.

Re: Acetone vs alcohol for degreasing.
Porbably the best reason to use acetone is that it leaves no residue when it evaporates. Denatured alcohol has a small amout of peproleum oil added in the denaturing process.
If your work does not require WC x-ray then it probably does not make much difference.

Re: Acetone vs alcohol for degreasing.
Ethanol is a very polar molecule so is not as good a solvent as many straight alkanes or aromatic solvents, particularly for hydrocarbons like automotive oils and greases. The government has, for it, dozens of approved denaturants including gasoline, diesel fuel, methanol, fusil oil, pyridine, etc. Methanol is often both cheaper and a better solvent than ethanol but for most of the contaminants I run into during shop work, acetone is far superior than either alcohols.

Re: Acetone vs alcohol for degreasing.
I am gonna butt in here. Haven’t really said much, but lurked in the shadows for some time.
One of the things to look into is what residue is left after the product is used. As being a automotive tech for 20 years, have run into a lot of different brake cleaners. How I was taught for brake clean residue will also hold true for most cleaning chemicals. With any chemical, spray or wipe it onto a clean piece of glass. Once it has dries, look at the glass. One of the best windows to use is the kitchen window, cause if it is hazy, you sure hear about it from the wife. I know with brake clean that the better ones will not give any haze. You sure know when you have a lower grade of chemical when you inspect it after.
As far as I can figure this should hold true also for the chemicals mentioned. There are tones of product all under the same name, but the quality is different for each manufacture. Then there is the unseen differences between different chemicals.
This test is for chemicals that vaporize fast.

Re: Acetone vs alcohol for degreasing.
Pour some denatured alcohol in a (clear) glass, pour some oil in there too, shake it, swirl it, do whatever you want to do to get it to blend then let it set over night and check the mix in the morning.
Do the same with some acetone and any other of your favorites you may want to chose from at the same time. Everybody can view the results and come to a consensus from there. Plunk in some costs, risk factors and other pros and cons. Maybe get in a bit of friendly debating while you’re at it.

When it comes to removing nail polish, there can be some confusion between acetone vs alcohol for nails. Two of the most popular options for removing nail polish are alcohol and acetone, but what is the difference, and which one is better for use on nails? We’ll go over all of that in this post!
The key difference between alcohol and acetone in scientific terms is that isopropyl alcohol has a C-OH group in the middle of its chemical structure, whereas acetone has a C=O bond in the middle of its chemical structure.
Acetone is a ketone, and ketones can be reduced to alcohols. Basically, acetone is stronger (often used as a paint thinner), and alcohol is more often used for cleaning and disinfecting without damage.
Acetone vs Alcohol for Nails
Alcohol is a good choice for cleaning nails and nail tools because it is a relatively mild disinfectant. It can remove dirt and bacteria from the nail surface.
It also helps to reduce the appearance of cuticles and can help to reduce the amount of oil that is produced by the nails. The only problem is that alcohol can be very drying and it can cause the nail to become brittle or cracked if you use it too often.
Acetone is a stronger solvent and is usually used for removing nail polish or even removing artificial nails. It is generally considered to be harsher than alcohol and can cause the nail to become dry and brittle if it’s used too often.
Too much acetone can also damage the nail bed and cause the nail to become discolored. Acetone is also a flammable liquid and can cause irritation if it gets on your skin.
Alcohol and acetone both have their pros and cons when it comes to cleaning and protecting nails, but if you’re looking for the best way to remove polish, go with acetone.
Can Rubbing Alcohol Remove Nail Polish?
The short answer is yes, rubbing alcohol can be used to remove nail polish. Since it’s not a strong solvent like acetone, it will definitely take more time and effort to remove the nail polish, similar to non-acetone removers that just aren’t as harsh as pure acetone.
Still, alcohol will work faster and easier than some other alternatives that we’ll talk about below.
It’s a beauty industry simple secret that alcohol works great as an effective cleaner to remove residual oils from the nail bed. This preps your natural nails for polish, gel nails, or fake nails by removing excess moisture which makes all of these types of nail applications adhere longer.
The truth is though, acetone does an equally good job at this step, so you may not need both in your lineup of nail products.
Non-Acetone Nail Polish Removers
A nail paint remover that doesn’t contain acetone is a much more gentle product for your skin and your nails. Non-acetone removers are usually used to change the polish on nail extensions because the acetone will weaken the acrylic nails.
Acetone is typically used to remove nail extensions by soaking the nail, which essentially dissolves it until it separates from the real nail.
Other Ways to Remove Nail Polish
Have you ever been in need of ridding your nails of old polish and found you were out of acetone or non-acetone nail polish remover? Surprisingly, there are some random things that also work to remove nail polish and the good news is that you probably already have most of these in your home.
However, you should keep in mind that you’re going to have to put in a little more elbow grease with these products since they aren’t as harsh as products meant specifically for nail polish removal.
Don’t forget to reach for the rubbing alcohol before these other alternative methods. Most of these household products are going to be much less effective solutions for the job, but when you’re in a pinch they could really save the day.
If you have gel polish, glitter polish, or artificial nails, these products will take extra time and effort to work.
To improve the efficacy of these emergency methods, soak your nails in a small bowl of warm water for 15 minutes before using any of these products. Since they are much more gentle, they’ll need a little help softening the polish, and warm water should do the trick.
Zubní pasta
Scrubbing your nails with baking soda-based toothpaste may do the trick. It has to be a non-gel toothpaste, though, since gel ones won’t work. Put a small amount of toothpaste onto a cotton ball, and then rub it over your nails until the polish is off.
Ruční sanitizer
Hand sanitizer contains alcohol so this is a good alternative when you need something close to nail polish remover. Simply pour a bit onto a cotton ball, and then rub it over your nails in a circular motion until the polish is gone.
Ocet
White vinegar is a kitchen staple that most people have on hand at all times. It’s acidic and is a good solvent for nail polish. Maybe not excellent, but good enough to do the trick when you’re in need of an alternative to acetone or non-acetone polish removers.
Remember to soak your hands in warm water first, then pour some vinegar onto a cotton ball and then rub it over your nails until the polish is off.
Citronová šťáva
Lemon juice is another great way to remove nail polish without remover. Lemons contain citric acid which makes them an effective solvent, although still a gentler option. For an even better DIY nail polish remover, you can mix lemon juice and vinegar and then rub it over your nails until the polish is gone.
Lak na vlasy
You may have heard that hairspray can take nail polish out of clothes or other fabrics, but it can also remove nail polish from your nails.
Just spray a bit onto a cotton ball and then rub it over your nails until the polish is off. Hair spray will have a drying effect on your nails and skin, so be sure to wash your hands well after using this to remove your polish.
Deodorant
This one might be surprising. I know it sounds weird, but spray deodorant might save you in a nail polish emergency. Only spray deodorant will work because believe it or not, they contain alcohol and acetone.
This method is going to be the most time-consuming but it should eventually work with some effort. Simply rub a bit onto a cotton ball or paper towel and then rub it over your nails until the polish is gone.
Alcohol and Acetone Products for Nails
Beauticom Alcohol Pushdown Pump
Tento šikovný push down pump bottle makes using this alcohol really easy. Pump bottles are the easiest way to use nail products since you just need one hand and a cotton ball or cotton pad to dispense the alcohol. This is really helpful when you’re doing your own nails.
Pronto Acetone Nail Polish Remover
Jakmile použijete aceton for nail polish removal, you’ll never want to go back to other types of nail polish remover. Acetone makes the process so much easier and gives you the best result in the least amount of time.
Just make sure when you purchase this product that acetone is the main ingredient as in this Pronto product, or it becomes less effective.
Proč investovat do čističky vzduchu?
There are several different ways to remove nail polish but the best option is the one that does the least damage to your nails while providing the results you need.
When it comes to acetone vs alcohol for nails just remember to consider all factors including the type of polish and/or nails you have on, how strong your natural nails are, and if you are willing to take the risk of potentially weakening your nails.
