Questions & Answers

does it work with the sprinkler siphon system
ByJul 29, 2026
1 Answer | 
Answer This Question

Hi Daniel, We have not tested in a siphon system, so are unsure if it would work. I would recommend using it on a small area before proceeding to make sure it doesn't damage the system.

            CAN THIS BE USED ON A COMMERCIAL DISHWASHER TO DESCALE IT?
            ByNov 6, 2025
            1 Answer | 
            Answer This Question

            Randy, Please refer to your specific equipment's owner's manual or their recommended procedure for flushing your dishmachine. We cannot guarantee our product would not void any warranty you may have on this equipment. If there's no warranty to consider then start with a 10% strength dilution and increase in strength as needed if you're not seeing the desired results.

                  After a lot of scrubbing, I did finally remove some of the stain. I guess I was just expecting more to be removed.

                    It does a good job of removing the rust stains from our gate on the pavers on the sidewalk.

                    Worked well as intended to help clean heavy calcium deposits on inside surfaces and grooves of kitchen sink spout assembly before installing new o-rings. Expensive, but definitely cheaper than the name brand- CLR. Only thing is there doesn't seem to be any mention of what the concentration is- so a little hard to compare. Gallon will last a long time, though.

                    No good at all!
                    This stuff didn't remove the lime on my bathroom tiles AT ALL. In fact, they look worse than they were before I used the stuff. - Useless
