RYDLYME Frequently Asked Questions




Q:  If RYDLYME contains HCl (hydrochloric acid), how can it be safe on my skin?
A:  Though the active ingredient is HCl, there is less than 10% of the acid, and it’s only one element of the overall formula. Couple this with the special way it’s blended, and you have a nice balance of safety, biodegradability and effectiveness. That’s what makes RYDLYME so unique and why similar products fall short.

Q:  Since RYDLYME contains HCl, should I be concerned about corrosion on stainless steel, such as hydrogen embrittlement? 
A:  There is no need to worry about hydrogen embrittlement. When used properly, RYDLYME’s unique formula will not corrode stainless steel or virtually any metal or material associated with water-based equipment. 
Q:  Does RYDLYME need to be used at a 100% concentration or should it be diluted?
A:  RYDLYME  is a powerful and concentrated descaler. Depending on the application, severity of buildup and available time, RYDLYME  can be diluted down to 25% while still maintaining its full effectiveness. To find out the proper dilution ratio for your specific application, please Contact Us.

Q:  How long will it take for RYDLYME  to dissolve the buildup in my equipment/system?
A:  Though most cleaning applications can be completed within a few hours, actual cleaning times depend on a variety of factors, including the size of the equipment/system, severity of buildup and method of circulation. Contact Us for an evaluation of your scaling problem and equipment to determine the proper amount of RYDLYME  and circulation method that should be used.


Q:  How can I tell when RYDLYME  is finished cleaning my system?
A:  In addition to experiencing improved performance, you can perform either a calcium carbonate spot test or pH test. These tests are explained in detail in our Testing the Effectiveness of RYDLYME information sheet.


Q:  In regards to your seashell demo online and in-person, I’ve seen other products doing the same thing with dissolving the shell in their chemical. What’s so special about RYDLYME?
A:  Look at those videos again. Are they dropping the shell into a container or palm of their hand? As previously mentioned, the safety element of RYDLYME is unmatched. You can put it in your hand or equipment without harm. Also, have an added piece of mind that you, your personnel and facility are safe in the unfortunate event of an accident, such as a spill or equipment failure.


Q:  Is RYDLYME safe in food processing or drinking water applications? 
A:  Yes! RYDLYME is NSF/ANSI Standard 60-certified, meaning it is approved as a safe drinking water treatment chemical. It is also NSF-registered for use in industries such as beverage, pharmaceutical, bottling and food processing plants.
