It can if you scrub well, but i imagine some of it goes down the drain intact.flyingpylon wrote: ↑Fri Mar 13, 2020 7:04 pm I saw a graphic that said soap can actually penetrate and destroy this particular coronavirus.
I don’t have any way to verify if that’s correct... hopefully it wasn’t just a meme!
You did read the article so must have seen this...dualstow wrote: ↑Fri Mar 13, 2020 7:00 pm I have a weird question: what happens to viruses when you wash your hands? Not with sanitizer. I mean if you mechanically remove them by scrubbing with soap and water.
It goes down the drain and then...deactivates because it can’t find a host? Disintegrates in the treatment plant?
From one of buying sprees from the 80s I still have bottles of isopropyl alcohol and hydrogen peroxide in my basement. For those in the forum who are far more chemically inclined than me don't those deteriorate with age, particularly that many decades? Though last year I did retrieve some Keri lotion from there that was of the same vintage and it seemed to perform as well as if I'd just bought it.dualstow wrote: ↑Fri Mar 13, 2020 7:13 pmIt can if you scrub well, but i imagine some of it goes down the drain intact.flyingpylon wrote: ↑Fri Mar 13, 2020 7:04 pm I saw a graphic that said soap can actually penetrate and destroy this particular coronavirus.

Btw, thank you for that (Yahoo) product list, Vinny. My wife found some bottles of HYDROGEN PEROXIDE that I had tucked away to make bleach, and it’s on the list.
Nope. I know how to kill the virus, but I am curious about that which gets washed down the drain intact. Nevermind the scrubbing. Let’s say you sneeze while washing your hands and some droplets go down the drain.Does that answer your question?
Regarding those "good until" dates? They mean nothing. They are not regulated in any way. Therefore the manufacturer can choose any date.dualstow wrote: ↑Fri Mar 13, 2020 7:40 pmNope.

As for your isopropyl alcohol question, I am looking at a bottle stamped 2017 that says it is good until Oct 2020.
I’ve been wondering about Libertarian666’s rice that he said he bought for Y2K. That’s 20+year-old rice!
I think I'd agree that while it would not turn into something dangerous it may have lost its potency to do the job for which it was created. But that time is probably long past its "best-by-date".dualstow wrote: ↑Fri Mar 13, 2020 8:36 pm I sometimes take expired vitamins because I’m aware of that which you wrote, but I don’t think I would trust a disinfectant that has passed its best-by date, let alone something from the 80s. I might use it up, but I wouldn’t count on it for killing a virus.
Maddy, I'm so sorry I've inadvertently given you Bidet PTSD! It's actually an extremely civilized and nice amenity to have. It doesn't make a mess, it's not only not uncomfortable, it feels nice. Read the reviews on Amazon if you don't believe me. Some people are wickedly good at delicately put, graphic descriptions.Maddy wrote: ↑Fri Mar 13, 2020 4:29 pmI dunno, I'm picturing water all over the bathroom, then having to don a hazmat suit and rubber gloves to clean up the mess. I think I'd rather go outside and use a garden hose. If it came to that. With soap. Lots of soap.Libertarian666 wrote: ↑Fri Mar 13, 2020 3:26 pm No, it's actually very nice. I'm sure the "pressure hose" terminology was for dramatic effect.
I can't imagine how isopropyl alcohol could lose potency. It's a fairly stable chemical compound.dualstow wrote: ↑Fri Mar 13, 2020 8:36 pm I sometimes take expired vitamins because I’m aware of that which you wrote, but I don’t think I would trust a disinfectant that has passed its best-by date, let alone something from the 80s.

Supports what you said.Hydrogen peroxide. You need to replace hydrogen peroxide six months after opening it, but it will last for three years unopened. To test whether it is still effective, you can pour it in to the sink and see if it fizzes and bubbles. If it does, it's still good. Expired hydrogen peroxide is ineffective but not harmful.

All I know from googling iso~ alc~ is that it doesn’t last as long once it’s open. Perhaps that’s more evaporation than degradation. If sealed, the main problem from a very old bottle would be the bottle itself. Maybe long term storage should be in glass(?)
Well, for certain types of alcohol it's not evaporation but consumption.
But for isopropyl, if the bottle is closed tightly it should be fine as far as I know.
I've never seen glass bottles of isopropyl but they certainly could exist. It usually comes in plastic quart bottles.
Thank you.

Hydrogen peroxide, however, isn't very stable, so I wouldn't trust old H2O2.
I wouldn't do that. I think it will remain useful in plastic for longer than the duration of this pandemic, and glass bottles are a major injury risk if you drop them.
Sure, glad to help.yankees60 wrote: ↑Sat Mar 14, 2020 8:15 amThank you.

Actually have a large old (30 year + ) bottle myself in the back of the garage - nothing has evaporated.dualstow wrote: ↑Sat Mar 14, 2020 6:03 am Good to know.
