I bought this for a specific purpose, which this peroxide worked great for, now I am using it in my laundry and all kinds of applications. It is easy to dilute and use for many things. I appreciate the included fill slash guard.

It's great. I use it in my laundry when I can't use bleach. It burns the skin so you have to be careful to wash it off immediately or wear gloves. Keep in mind that it is a harsh chemical so use accordingly.

if you’re looking for a quality food grade peroxide this is it. I use this for clean wounds, cleaning scale off of sinks and drains. Can’t say enough about it.

4.0 out of 5 stars Great laundry whitener, but pricey

L.F. · February 16, 2025

I bought this to whiten laundry. It is so much more powerful than standard drug store hydrogen peroxide.I add one cup of this to the laundry cycle along with the detergent and OxyClean (yes, I use this with OxyClean - it seems to make everything work better).As long as I add this only to machine washable, bleach safe fabrics directly in the water (and not directly to the clothes), I’ve never had any problems with it damaging fabrics. I mostly use on our white bath towels and white bed sheets, so this is never a problem for us.The only reason for 4-stars and not 5 is due to the high price.

Diluted a little and used with a spot cleaner to remove urine stains from toddlers on a matters. Worked like a charm. Definitely recommend.

Peroxide is great for cleaning. Many uses.

12% peroxide - great find!

Great product

Use this in my hydroponic system to keep the unit clean and strengthen the plants roots

Was Exactly What I Needed!!

Over the past year I have tried just about everything I could find to eliminate puppy pee smell from the grout in the bathroom tiles and nothing I tried worked. That is.....until I tried Harris 12% Hydrogen Peroxide. Within 24 hours the lingering smell was completely gone. I suppose I didn't need to purchase such a large jug but I am not sorry. There will be other uses. I highly recommend this product!

Tested the PH

S. · December 9, 2024

Some are writing that this product is just water, I opened my jug 4 months ago, tested the PH today and it's around 4 on the PH scale, indicating at least 12% peroxide.

''Fresh''

Came as advertized. But shipper doesn't advertize that they will drop packages in front of door. Good grief! Not an issue with product but Bolo might pass it down the food chain that the shipping component has to smarten up! It wasn't this bad yesteryear(s).Was a bit of a leak from Einstein dropping the big jug. But turned out no damage other than a big welt across side of bottle.Great way to save, and contents fresh and as advertized. Highly recommend. Not the shipper, however.
