a good antibacterial soap is the best thing to wash your hands w/ b4 working with sterile items but washing your hands 10 times a day gets old. does anybody use hand santizer instead of soap? its active ingredient is 62% ethyl alcohol and it "kills 99.9% of most common germs that may cause illness."

This is what I use.
It's the same cleaner used in labs, hospitals and EMS units. After a day of use, make sure you use a good hand lotion at the end of the day. It does tend to dry your skin.

It works fine on glove, but not on skin; your hands develope a layer of grease as you go through the day, and it's in this that germs begin to develope. Washing your hands with soap removes this layer, and thus the germs, but a waterless hand sanitizer won't. It'll work great if you use it after washing your hands, but not as a substitute for washing as it won't penetrate the grease layer.

i would NEVER touch mycelia or anything i wanted to keep sterile with my bare hands. it has been proven impossible to truly sanitize the human hand w/o causing some sort of trauma to the skin. always use gloves.

1st of all fellas good luck to all ur myco pursuits and may u have a absence of contams. just a small opinion. i would never use ethyl alcohol for cleaning or sterilizing anything if i could get methanol,isopropyl or denatured alcohol. of course all these are available at ur pharmacy,supermarket or hardware...if im not mistaken i think u drink ethyl or ethanol . unless in ur area thats only stuff(?) available, since it can be produced from local fermentation/distillation.

thanks for all the feedback fellas.
the stuff i'm referring to is "Purell instant hand sanatizer." your supposed to rub it in your hands for 10 seconds until it dries. my only concern was how it says it kills 99.9% of germs- this probably doesn't include the bacterias that we carry on our hands. wearing gloves is probably the safest way to go.

I think wearing latex gloves then spraying them with lysol or dipping them into methanol works just fine.

god almighty, people! why the preference of methanol over isopropyl or ethanol? methanol is highly toxic and can be absorbed through vapor and through the skin (think blindness, insanity, death). ethanol works great but is definitely too pricey when compared to ispropyl. isopropyl is dirt cheap and can be cut with water (as any alcohol can be), hell.. it is actually more effective when cut with water to ~40-50%. personally, i'd avoid methanol if it involves any kind of contact with skin or prolonged exposure to vapors. care to enlighten me as to why you guys think it is so great? BTW, the sanitizer i use on latex is Purell as well. i keep a pressurized garden spritzer full of 40% isopropyl to cleanse surfaces, the air, my skin, practically everything. i occasionally use bleach to clean walls, bins, and to mop floors.

thx for a better update linuxer , i didnt mean to go mutagenic or anything..i yeild to greater fleshware and cover my substrates " i will not go near wood alcohol again!" u can get isopropyl in strengths up to 99% in the normal size bottles right in some local drugstore. indeed its what i use 4 my sterilizing lamp and also 4 my pinkys. ps i also use bleach alot. but i do hav e one quest about about the use of alcohol. i dont kno, what is the advantage when u cut it with..h2o,as far as its effectiveness as a sterilizer???

alcohol used at too high of a concentration can cause bacterial endospores to go "shields up" because the conditions are so harsh. when cut with water the bacteria is "fooled" in a snese and fails to protect itself. you get the added bonus of getting more sanitizer for you $. that's a pretty rough description. the concept has been covered several times right here in this forum and in advanced cult. try a search for something like "alcohol endospore water" to find a better explanation.

Bacteria does not form endospores when exposed to high concentrations of alcohol. Its the fact that pure alcohol evaporates extremely quickly.
Alcohol mixed with water (alcohol is extremely hydrophilic, ie. it attracts water) lasts much longer and has a more effective contact time.
Alcohol dissolves the cell membrane of bacteria. Pure alcohol disolves the membrane just as effectively, if in contact for an appropriate amount of time. The proteins used in the makeup of an endospores cell wall are just as affected.
Just clarifying the reasons behind this :-)

Also, I should note that methanol IS rather toxic. What I meant by methanol was simply commercial ethanol thats been denatured by methanol. They simply add some to make it toxic so you dont drink the stuff. Also you must use it in a well ventilated place and not let it come into contact with your skin.
Better off with 70% isopropyl or ethanol. I use the denatured stuff for flame sterilization and do rub it on glove covered hands but am wearing a mask and standing in front of a hood.

thz to both of u for helping to refresh the knowlege base. i will try and remember to cut that 99% isopropyl stuff in half to double it volume and to more effective use it against fungal enemies or aleast cut it some. i think the 99% stuff has a place though that in the alcohol lamps. the 70% stuff will work but it sputters i think because the present of wate. so 70% bottles sterility and 99% ones for lamp fuel. anyway thx all.
