This is something that will clean toilet tanks and bowls but use it cautiously and with gloves. It is very corrosive to skin. I use it as if it's comet. Turn off the water, flush and then scrub the bowl and tank Turn water back on, Let the tank soak abt 20 mins and flush a few times. You can get water spots of glass with this too and clean showers (porcelein) and tubs. I wouldn't use it on fiberglass or other similar products.

I've been using this brand for several years for OAV bee treatment. I do not have high mite counts ( but you have to apply as necessary to keep the mite count down).

Work really well

Prompt shipping, good product, excellent delivery

I have issued in the back of my house it looks like a tiny house the sprinkler system put a brown Haze from iron in the water over it. I sprayed this on the tiny house / shed and it took the brown haze off the house with no scrubbing it didn't even kill the grass I would recommend this to anybody

Our yard is full of quartz that is covered by red clay. This cleans them well, I just use a little in a large crock pot with distilled water and it works super well. I just reuse a few times then neutralize it and dispose.
