Review: Very effective for toilet bowels with heavy rust deposits - I bought this product to finish the removal of hard water rust deposits in my toilet bowel. It worked very well, but note my caution about how to deal with the chlorine fumes it produces. I initially used ZEP Acidic Toilet Bowl Cleaner. I emptied the bowl (not the tank) using a small electric pump and then poured in about 2 cups of ZEP. I let it sit for 15 minutes and then used a toilet brush to remove the rust deposits in the bowl and around the rim. This removed most of the rust but some thick stubborn bits remained in several small recessed areas. The ZEP product contains 10% hydrochloric acid. I reasoned that I needed something stronger and found this product containing 30% HCl. It is somewhat pricey but I was determined to finish the job. I emptied the bowl, as before, and poured 2 cups into the bowel. I let it sit 20 minutes and, wearing heavy rubber gloves, used a Brushtech Flexible Drain Brush (22" long, bristle head 1.25" diameter and length) to scrub the small recesses in the bowl where heavy rust deposits remained. Because this product is so strong, it produced chlorine fumes that irritated my lungs. Fortunately, I had on hand a North half-face respirator mask (model N7700-30, comes in 3 sizes, S,M,L) and filter cartridges for HCl and Cl gas (N7500-3). If you don't have this gear, you will need to use a big fan to properly ventilate your work area. After the scrubbing, I flushed the toilet 5 times to remove the acid and then used my bare hands and a Scotch-Brite scour pad to get at the recesses containing the now-softened rust deposits. This finished the job -- my toilet bowel is now rust-free.
Review: Good Quality - I use this hydrochloric acid with Sodium Chlorite, 80% Flakes, to make Chloreene-dye-ox-hide. The result is an excellent solution.

## Questions & Answers

**Q: How do you open this? Specifically, once you get the screw cap off, there is a red inner cap. Do you puncture this or wedge it out?**
A: I don't know an easy way to remove the red seal. I've tried drilling through it, but the drill bits can contaminate the acid.  So I use needle nose pliers to pull it out, but I have to be careful not to spill the acid so that it doesn't get on the pliers.  This works, but it isn't easy.  I wonder if there is a special tool the vendor can supply?

**Q: The hcl from the bottle i bought is yellow (like pee) - is this normal? shouldn't it look like water?**
A: You can test for contamination by boiling dry a small amount of acid and checking to see if there is any residue.  I once asked the manufacturer of this acid if the pale color indicated contamination and they assured me the color is normal.

**Q: 100ml hci + 600ml distilled water = 4-5%hci correct?**
A: To me that mix would be close to 17%

**Q: Looking to liquify some old phones so data can never be recovered. Will this stuff work ?**
A: Yes will destroy all of the data. Let the device stay in the solution one whole day
