Nah, it’s too good to be true

We address some common questions regarding RYDLYME Biodegradable Descaler.

Though RYDLYME has been around for more than 70 years, it continues to amaze customers, new and current. Any initial concern or skepticism with such an innovative product such as RYDLYME was diminished after learning about it and seeing it in action.

With each new generation of worker and competitive product that come into the market, there are new (as well as old) questions and misinformation about RYDLYME. Let’s go over them.

If RYDLYME contains HCl (hydrochloric acid), how can it be safe on my skin?

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.

Think of it like this… a good chef adds some kick to his dish by adding jalapenos, but balances it out with some honey and other ingredients to strike the perfect balance, not just toss in some more pepper and ring for pick up. 

Is RYDLYME safe on metals, including stainless steel? What about other materials?

RYDLYME has been proven safe on numerous materials associated with water-based systems, including stainless steel, aluminum, copper and more, not only by our customers, but also certified independent laboratories. It is also safe on rubber, iron, ceramic and glass. 

Those three letters… Any skepticism from those unfamiliar with RYDLYME or misinformation from our competitors usually stem from only focusing on HCl. FYI, being only a small component of the overall RYDLYME formula and how it’s blended makes it safer, yet still more effective than other products. LOL.

The food and beverage industries have strict guidelines when it comes to cleaning products on a variety of equipment. Can RYDLYME be used in these industries?

Absolutely. RYDLYME is NSF/ANSI 60-certified for use in potable water system cleanings in beverage, pharmaceutical, bottling, poultry and other food processing plants. Transportation is also not a problem, which makes it a cost-effective solution. RYDLYME is categorized as Class 55 (Non-regulated/Non-restricted; can be mailed or shipped by any private or commercial carrier without restrictions). 

Something else to keep in mind… though RYDLYME is used at a significantly diluted rate; it’s biodegradable even at 100% concentration, as certified by an EPA-approved facility. Apex Engineering Products is also an ISO 9001:2008 Certified Company and held to strict safety and quality standards.

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?

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. CLICK to view our seashell demo.

Just for kicks… The next time you come across another in-person demo, ask them to put the chemical in their hand rather than a container. Then watch the look of concern and uncertainty come across their face. Priceless.

As with all product purchases, do your research. Inquire about products with your peers, as well as the product manufacturer and users. Run sample tests to find out what product works for you. 

If you have any questions regarding RYDLYME, just give us call. With more than 70 years of experience and success, we know a little something about safe and effective descaling and cleaning.

RYDLYME goes into the boiler room

A 1,000-gallon boiler at a plant that processes feed ingredients for animals was experiencing overheating and significantly reduced performance due to excessive water scale. The customer wanted a solution that was not only effective at getting rid of the scale, but also fast and safe. RYDLYME was brought in to tackle the scale safely and quickly.


•  440 gallons of RYDLYME circulated for 6 hours (solution was pumped into the bottom of the boiler and out the top)


•  After circulation and thorough water flush, the entire boiler was free of scale and returned to peak operating efficiency.

•  The customer stated, “Outstanding! The boiler looked awesome.”

•  When asked about the difficulty level of doing this cleaning, the customer quickly stated, “RYDLYME is the easiest product I’ve ever used!”


Some boilers can take a great deal of abuse and inattention and still function at competent levels. They may even have davited and hinged doors to easily expose the tubes for inspection and cleaning. Regardless of the type and design of your boiler, the deposits should be monitored by visual inspection, tube sampling, or other methods.

Cooling tower of power

Get RYD of the water scale that may be jacking up your energy bill.

The basic principal of a cooling tower is to cool the water that has picked up heat generated by equipment within and around a facility. 

The operation begins in the tower basin where the cooled water is pumped out into the facility and utilized for cooling the equipment on the tower system. As that equipment is cooled, the water picks up the heat and returns to the top of the cooling tower. The hot water is distributed onto a hot deck or through the spray nozzles that evenly distribute it over the tower fill media. 

The tower fill media is designed to increase surface area, as well as contact time between air and water. This enhances evaporation and allows further cooling of the tower water. The water then falls into the tower basin where it is then pumped back into the facility to cool the system equipment.

Scaling within a cooling tower can restrict the water distribution of spray nozzles, reduce the water flow through the openings of a hot deck and restrict the air flow within the tower. All of these conditions will result in diminished cooling capacity and inefficient operation of the associated equipment on the cooling tower system.

A cooling tower system can be cleaned by adding RYDLYME to the tower basin, thus allowing the towers transfer pump to circulate the solution throughout the tower and the equipment it is cooling. This can be accommodated during the normal operation of the cooling tower without shutdown! It is imperative when calculating a required amount of RYDLYME needed for a cooling tower system to include enough RYDLYME for the equipment load of the tower.
