Knock Out Household Ammonia, 500 ml

Strong, effective cleaner that tackles grease and stains easily. A little goes a long way and it leaves surfaces fresh and spotless. Great value for money.

Great product and exceptional customer service. Their customer support team is very helpful and friendly. I have purchased from them in the past and will continue to. Thanks again!

I use Ecover detergent or a similar bio degradable product. And it does an okay job, but every few months of regular washing my hats, clothes, pillowcases and towels become clogged up with grease or soap scum and they smell bad. The answer I have at the moment is to soak them in ammonia (1 tsp per 5l or so of hot water), which dissolves the grease out of the clothes and after a normal wash they are back in business. It would be easier to put the ammonia into the washing machine, but I'm not sure that would be good for the machine, so I use this labour-intensive method which works okay. I'm giving 4 out of 5 because I would prefer a washing-machine-safe version although this product does do the job on all types of fabric I have tried it on - cotton, wool and synthetics apparently without any damage to the clothes. It smells very nasty and rubber gloves, eye protection, caution are needed in a ventilated area.

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 :)

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

Glad to find this, cannot find it in the shops anywhere these days.

Good product, well packaged but slow delivery - 4 days
