Alconox Detergent Cleaning Concentrate 4 lb. Container

This is the best product for getting hard water stains and stains in general on scientific glass or any glass!

By far the best glass cleaner I have ever used. Super versatile but it is a beast with glass and stainless steel. Will make them look better than brand new and leaves zero residue. Best off one tub of the stuff lasts a long time as you only need about 2 tablespoons to make a gallon of liquid cleaner. Can't go wrong with this one!

I use this at home; a little goes a long way. I last ordered in 2014, it's now the end of 2025, and I am now needing to resupply. It takes care of what the other detergents just won't. stains in the cream Le Creuset disappear. The buildup in the coffee cup from the office that the dishwasher won't touch wipes away with a swipe of a finger after soaking. It is my go-to for the hard tasks.

I use this for cleaning extremely greasy things like hood filters, and greasy surfaces in the kitchen. It's extremely effective for cutting through the the goop that accumulates on the mesh in the filter. I just pre rinse the filter (with cold water to keep the grease from clogging the pipes), then I partly fill the sink, and finally I pour in a teaspoon of this stuff (pretty strong). After a bit of mixing, I start scrubbing, and I'm usually done in less than a minute! For surface cleaning, I mix up a bit of this stuff in a sprayer bottle and spray the surface I want to clean. Then I scrub/wipe it off with a paper towel (so I can dispose of it and keep it out of the sewer). NOTE THAT THIS IS A PHOSPHATE DETERGENT! You probably shouldn't use it for daily dishwashing, since phosphates are really bad for the environment - they cause nasty algae blooms and other eutrophication problems! If you don't want this stuff banned for home use, don't use tons of it. Also: if you live in areas where water treatment is marginal or with high levels of phosphates in groundwater probably think about using this stuff carefully! Update, a few years later: it turns out there are a few other specific uses that Alconox is excellent for. Cleaning chemical labware (which I need occasionally, testing my garden soils), and cleaning my CPAP/APAP machine. It turns out I have sleep apnea, which is quite a surprise for someone my age, but I'm benefitting quite a bit from CPAP therapy. These machines need to be cleaned frequently, and I can't afford leftover dirt, suds, or any kind of residue. I also can't use anything harsh, like bleach, and don't want to use any solvents like ammonia. Alconox was made for this. And it's perfect. I need very little of it - I'm still using the same bottle that I bought like 5 years ago now - and it means way less scrubbing and rinsing.

The picture of this product shows it in a paper carton. NOTHING could be farther from the truth. It arrived in a plastic container. This pleases me in 3 ways. 1) As the Chemist of DOOM, I like environmentally damaging things like plastic- I prefer plastic over paper, because paper is very ecologically friendly- it involves trees and sulfuric acid and stuff, all naturally occurring. Plus, paper manufacturing is easily powered by unicorn farts. Plastic is made with all artificial stuff like hydrocarbons. 2) A picture of a paper carton, actual product in plastic? False deceptive advertising. I like this too. 3) I haven't actually used any yet. True to form, when my experiments fail, I throw the glassware on the floor and break it. Not only does this look dramatic as heck, but it saves me from having to use my precious plasticized Alconox Detergent. Plus, I'm far too important to clean glassware. But I know this stuff works great- I used it last century when I was working on my B.S. Evil World Conquering Chemistry at the Royal University of Latveria. They made you pay for any glassware you broke there, so I couldn't just go around smashing stuff theatrically.

0 Smell, extremely effective (careful with labels and such) easy to follow directions, small amount goes a along way when cleaning most things. Valuable asset in any house hold

5 OUT OF 5 STARS At this price I will continue to purchase from this seller. Product delivered not damaged. Additionally, this item was delivered according to scheduled.

Have used this for years as a piercer. It works well and you don’t need much. I just wish it came with a scooper to measure how much you are using. Overall great product, great clean, and great value.
