15% sodium hypochlorite?

Mar 28, 2009

Yes, Mitch uses 15% and just cuts it down more.

Experiment with it and you'll figure out how much to use.

Depending on who you are buying your bleach from and how old it is (freshness) will determine it's strength.

sodium hypochlorite can range anywhere from 10%-20%

Thanks Mike that answers my question!

Also Mike does the same go for the Alcohol? Because Wal-Mart sells both 91% and 70% percent.

I haven't seen or tried the 91% alcohol from Walmart here in Greensboro.

I would mix it the same.

If it comes in a 32 ounce bottle like the 70% does then you might as well use the whole thing.

Just got 5 gallons of 25% SH factory fresh from a friend that works their.
(I am a little afraid to open it) ashamed
Wish I could get it all the time.

SO anyway my distributer told me my SH is 15% by volume 12.5% by weight.� Maybe I have those backwards.� I think some people who have 12 or 15 might actually have the same thing ??

I got 2 gallons of 99% ISP at my local Wal-mart @ $1.79 per quart, the 3 closest distributers to me wanted around $20 per gallon!!� Anyone know why it is more expensive through the distributers?

I was told that if you buy 15% SH when it hits the air it goes to 12.5%. Thats what a janitorial suppy person told me. Kipp

I have never heard of buying 15% or more SH??
Is it really possible?
PS This is post # 100 for me, so it's certification time for me!!!!
HURRAY!
I think being "certified" will make a difference, especially in internet advertising!

From speaking to our local chemist, it seems that 15% degrades to 12- 12.5% rather quickly, where it starts to stabilize for a short time. Most all SH is manufactured at around 15-16%, but by the time it reaches the consumer, it is between 10-12.5%.
