Vinegar can be an effective alternative to harsh cleaners. However, as a disinfectant, vinegar has limited uses. It can only kill or reduce certain…. These are the areas that can harbor germs — and the best way to disinfect them according to experts.
Your toothbrush can harbor bacteria from your mouth. When looking for products like household cleaners or hand sanitizers that can kill germs, opt for ones that indicate at least 60 percent ethanol or 70 percent isopropanol as an ingredient. Plus, ingesting these products poses life threatening health risks.
At the required concentrations — between 60 and 90 percent — alcohol can kill a broad range of germs, including bacteria, viruses, and fungi.
For example, alcohol can eliminate common bacteria, such as E. Other bacteria, such as Enterococcus faecalis , are becoming more resistant to the effects of alcohol-based disinfectants. Alcohol has also been shown to kill viruses such as herpes, hepatitis B, HIV, influenza, rhinoviruses, and coronaviruses, among others. Finally, alcohol is also effective at destroying fungi, such as Blastomyces dermatitidis and Coccinidiodes immitis , which can cause fungal diseases. When choosing an alcohol-based disinfectant, remember to look for a product with an alcohol content of at least 60 percent.
Keep alcohol-based products out of reach of children and pets. Also remember that alcohol-based products are flammable and should be kept away from flames. Keep these products sealed to prevent evaporation , which can weaken the concentration of the alcohol.
Follow the guidelines below when using an alcohol-based product to disinfect your hands or household surfaces. Follow these guidelines to use an alcohol-based product to disinfect your home :. Using soap and water is the best way to kill germs on your hands.
To wash your hands , wet them thoroughly with water, lather them with soap, and scrub for at least 20 seconds. Then rinse and dry them. That represents a safety margin, due to the challenge that may be faced in the health care practice. Therefore, the effectiveness or efficacy of alcohol disinfection, even when it is conducted with no previous cleaning of instruments, is not possible to be reached, as verified in this systematic review, because organic matter is present in the health care practice, at levels which are the same or below the ones which were analyzed in laboratory tests.
Also, the reach of alcohol disinfection, in laboratory and field conditions, either with or without previous cleaning of instruments, may be related to the diversity of health care products, which are classified as semi-critical and differ both in regards to their structures and to the quantity and type of organic matter and microorganisms after such products are used.
Those factors were not taken into account in 1 , when authors classified the articles according to their potential risk of acquiring infections, thus simplifying the potential risk levels without taking into consideration the differentiated levels that possibly existed within those categories, in particular the ones considered as semi-critical.
Scientific knowledge so far leads to a reflection on how insufficient it is to use a classification that was proposed in , intended to define guidelines for the processing of articles. The type of procedures in which products have been used, and the microbial and organic load that is found in those products, after being used, are known to result in varying degrees of difficulty in regards to cleaning and disinfecting them - that fact has.
In this literature review, alcohol disinfection was observed to be satisfactory for health care products such as nasopharyngoscopes E2 , laryngoscopes E11 , radiographic films E5 and E10 , and tonometer tips E Those health care products do not have grooves and are not tubular; that is, they are less structurally complex and get in contact with a smaller amount of contaminants as compared to gastrointestinal endoscopes, in which alcohol disinfection was not shown to be satisfactory in this review.
Theoretically, the conduction of previous cleaning favors the action from disinfectants on microorganisms. However, the findings in this review surprisingly do not reinforce such information.
However, out of the previously cleaned devices which were analyzed for alcohol disinfection effectiveness are nasopharyngoscopes which were used with protective covers during exams, which may optimize the cleaning and disinfection process, as the equipment does not directly get in contact with patients' mucous membranes during exams. None of those health care products was found to have microorganisms after decontamination processes.
The presence of protective covers is believed to have influenced those results, and it is a characteristic which differs from the analysis of the remaining equipment.
If we eliminate that variable use of protective cover the percentage contamination of previously cleaned, alcohol disinfected products under field conditions would be Thus, in both conditions experimental and field studies , the percentage detection of microorganisms was higher for previously-cleaned health care products.
Regarding those data, it is worth highlighting that the numbers of previously-cleaned and uncleaned products tested in both groups were different - they were and 64, respectively, for field studies, and 30 and 62 products, respectively, in experimental studies, which yielded higher percentage detection of microorganisms in groups with smaller quantities.
Besides that, the evaluated health care products are structurally different, and so are the methodologies that were used to find and analyze microorganisms. Therefore, interpreting those data must be done with caution. In this review, the methods used for alcohol application were rubbing and immersion, as shown in Table 3. The method regarding immersion in alcohol is not often used in the health care practice, and one of the reasons for that is the volatility of that disinfectant, which leads to the need of replacing solutions with each use.
However, that procedure was not described in two studies using the immersion method. Strictly observing the time period through which health care products were exposed to alcohol is one of the basic requirements for this disinfectant to perform accordingly.
The studies analyzed in this review used rubbing times which ranged from 10 seconds to 1 minute. In the ones using immersion methods, immersion times ranged from 20 seconds to 20 minutes. Among the five studies in which alcohol action resulted in the full elimination of microorganisms E2, E5, E10, E11, E13 , one of them E5 used a 3-minute immersion time and a second rubbing time. Another one E11 also used rubbing, for 30 seconds. In study E10, the immersion time was 60 seconds, and in other two studies E2, E13 , time of alcohol exposure was not described.
Variations in rubbing and immersion times that were found in the studies made it difficult comparing or defining optimal exposure times for products to alcohol. Several health care products with different risk levels within the semi-critical category were analyzed in this review, from tubular devices such as endoscopes, and ones with flat surfaces and without grooves, such as periapical radiographic films, which made comparing results difficult.
Besides that variable which made it difficult comparing obtained results, others may be mentioned, such as different techniques for microbiological sampling, different materials used for rubbing the alcohol, distinct methods for breeding and identifying microorganisms, and sample size variations. The diversity of products and results found in this review leads one to believe that disinfection procedures may be different according to the structural complexities of semi-critical materials, as well as according to the microorganism load, organic, and inorganic residue those products may carry after being used.
Standard protocols are observed to be required to be created and published, in order that tests for. Those protocols are suggested to include the items used in the studies, so the methodological strictness of studies can be evaluated.

The supplements you've mentioned have only been found to be effective against herpes in the test tube well not all of them have even been tested for herpes - they just in general area known to have antiviral properties. Most of them have not been effective when tried in animals so human trials have never commenced. You are spending a heck of a lot of money on supplements when odds are you aren't going to get more effectiveness than just daily suppressive therapy with 1 of the 3 herpes antivirals.
You are actually increasing her risk by wiping your genitals with alcohol. It's an irritant and irritants have been found to trigger shedding and increase transmission. The skin in the genital area is very sensitive and you are drying it out and doing more harm than good.
You'll never get it down to 0. I take it she's been tested to know her own status? Helpful - 0. I've found conflicting opinions on that. Thank you! Trauma in the genital area has long been known to trigger shedding too.
You certainly do not want to use alcohol on the skin and dry it out in general - never a good thing in general. I know of absolutely no references that show that topicals help to protect a partner when applied prior to intercourse.
