Knock Out Household Ammonia, 500 ml

Bought this to start an aquarium cycle off. It worked very well. There's none of the tell tale signs of there being anything other than ammonia in the solution. Based on the dosage I needed to reach about 2ppm (mg/l) of ammonia, I'd say that the strength is about 9.5%, due to the fact I needed 2.7ml to reach the concentration in my 120l aquarium. Now I just need to figure out what to do with the remaining 497.3ml of the stuff. Oh and don't be tempted to give it the whiff test, unless you like extremely unpleasant sensations in your nasal passages. Maybe go outside to pipette out some too :)

Brilliant works every time.

Good product, but the size is small. It only cleans two windows, lolololo, not enough for more.

Does what it needs to, I'm using it to increase the pH for the washing powder to be more effective and it works, laundry comes out immaculate from the otherwise subpar machine! Be sure to use gloves and don't smell it directly, it is very stingy!

Very strong smell value for money stain removal is excellent but be careful as it will take colour out of carpet but effectiveness’s is undeniably great , value for money could be better as it is a little bit more pricey than see hardware store

Definite recommend
