Building Block Hides

I say do it up man. As long as you pay attention to sanitizing it well on a regular basis it should work fine. There are a lot of nooks and crannies for bacteria to get into but a good bleach solution soak should take care of it.

Standard Clorox is only 6.15 percent NaClO by volume. 5% by volume for thirty minues is recomended for killing bacteria.

Once you get the hide built you could use superglue to seal it, and let it dry for several days so you do not have to worry about off gasing.

man, I have a ton of old legos sitting around too, that's a pretty cool idea

i didn't know this. they still recomend you dilute it by 10% when using it for cleaning.

They do that to keep the ambient particle rate well below the LCT/50 of 200 ppm. It makes it so people who are not smart enough to do it in a ventilated area, or fail to leave to another area while the solution soaks are unable to kill themselves by inhaling too much.

If you take a look at the back of a Clorox container you will see a table at the bottom, it tells you that ½ oz of the solution in one gal of water will give you 200ppm. That is not 200ppm of NaCIO that is 200ppm of Clorox’s mix. Call it a CYA thing.

By diluting it to 10 parts water, one part Clorox (different mixes can be seen on the back of the container), it makes it so you would pretty much have to drink it to kill yourself. Unfortunately that low of a percentage of NaCIO will not kill some forms of bacteria. Which is why the recommend a 2400ppm mix to kill off blood and bodily fluids, and then autoclave it (talking about hospitals and what not).

Sodium hypoclorite is an odd creature. You can smell it at 3.5ppm, but has a LCT/50 of 200ppm (Lethal concentration over time, that time being thirty minutes, in 50% of those exposed). And an initial (lethal dose) is about a thousand ppm, meaning it can be lethal after only a few breaths at that level. A 10% mix, in a decent sized room with an open door could give you about 100ppm by mopping on a hot day, but even that is streaching it. PPM will be lower if it is suspended in a bucket because evaporation will be slower if it were spread on the ground in a bleach water mix. But we will not be getting these types of concentrations from normal household bleach unless something odd happens like they throw it on a hot surface and it flash boils, or something as equally as dumb.

But anyway. If you feel unsafe using the percentage I mentioned, go ahead and use their recommended mixes, but let it soak for a longer period of time.

wow are you a chemist? i think i'll switch to a 5% solution after reading your response.

Nope. A little bit of my time in the Corps has been spent as a CBRN guy.

So will it make my soon-to-be lego hide cleaner quicker?

I actually have not heard of the chemicals you guys are talking about, here in South Africa I'm using something called F10CLXD (Quaternary ammonium and biguanidine compounds 1.16% non-toxic ampholytic surfactants and sequesterants/detergents)

Says on the back that it takes 2 minutes for bacteria at 1:200 dilution, the longest time and highest concentration is for Bacillis subtilis spores and parvovirus , 30 minutes at 1:25 dilution.

Don't know the technicals but it keeps my cages, bowls hides clean and fresh smelling:gj:

I don't really have much experience with quats. We don't use either in our decon processes because it is ineffective against endospores, mycobacterium tuberculosis, lipid-containing viruses, and pseudomonas spp. And they are deactivated by soaps and anionic detergents and some organic compounds.

Quats shouldn't be killing any type of Bacillis because they have such a robust endospore. Unless my brain is backfiring or something.

Sorry for the double post, I ran out of time to edit while I was bashing my head on the desk.

Using some types of antiseptics (biguanidine) may be why you get results against some things when used in conjunction with the quat.

The chemicals compound I was talking about was just regurlar old sodium hypochlorite. It may take longer on some types of bacteria than some antiseptics, but it kills absolutly every type. So in the end I believe it is more cost effective.
