Why did you choose this product over others?: I'd bought before and was Ok. Last batch weak, heavily diluted, did not work. Will not buy again

I dismantled the U-bend and tipped the water out to make sure it went in neat before pouring in the contents of almost both bottles. Did absolutely nothing after 1/2 hour. The stuff is so weak it has no detectable odor. Didn't even hear a crackle inside the pipes. In the end I poured a little bit on an outside paving stone and, yeah, it did fizz a little so I guess it's not completely inert. Label says "Less than 10%" concentration without being specific. I'll give it an extra star because I know by law they can't sell at higher concentrations.

Spirit of salts is always an excellent loo cleaner

This product was recommended to me years ago for dealing with heavily limes Alex toilet bowls. I had a particularly bad one to deal with and I didn’t waste any time and bought this again. You have to protect your eyes and airways as you apply it. I basically cover my whole head, eyes and nose, keep my mouth shut, pour it in the bowl and leave the bathroom and close the door. This time I left it overnight, in fact more like three days and when I went back, one flush and the offensive gunk was gone. Don’t throw the toilet away, but use this instead.
