RYDLYME Biodegradable Descaler: Not All Descalers are Created Equal


"It's Just Like RYDLYME."

That is the original marketing strategy that other companies have developed to sell their chemical descalers. Some products try to ride the coattails of RYDLYME, while others resort to creative wordplay to gain customers. But not all descalers are created equal.

RYDLYME has been around for more than 75 years and has earned the reputation of being the World’s Leading Biodegradable Descaler by countless customers and OEMs. RYDLYME has often been imitated, but never duplicated. While the proverbial phrase “imitation is the sincerest form of flattery” holds true in this case, it is misleading. It is putting the health and safety of customers, as well as equipment, at risk. The unique and complex formulation and blending process of RYDLYME gives it the ideal balance of effectiveness and safety. NO other formulation can duplicate that, and stating otherwise is grossly deceptive.
Let’s present the facts so you can make an informed decision when it comes to your next chemical descaler purchase...




The RYDLYME Advantage


RYDLYME significantly outperforms traditional mechanical cleaning methods (e.g. brushing, rodding, hydroblasting) when it comes to speed, effectiveness and efficiency. But did you know RYDLYME outperforms other chemical descalers not only in safety, but also speed and effectiveness?

In laboratory tests*, RYDLYME was as much as 12x FASTER and dissolved as much as 50% MORE than other chemical descalers! Also, RYDLYME offers a cost-savings as the product is so concentrated that only a percentage of the product is needed in most applications. A huge difference from some descalers that require as much as 100% concentration!

Additionally, the unique and complex formula of RYDLYME quickly dissolves a wide array of mineral deposits and is safe on all materials associated with water-operated equipment and systems, including copper, brass, rubber and even stainless steel all in a single product!

What does this mean to you?

Aside from the timely and arduous work involved in mechanical cleanings (e.g. dismantling, individual tube cleaning, cleanup, disposal), spending substantial time on jobs due to slow-acting chemical descalers costs customers and even service companies lots of money. Why spend a day or even several days on a job when RYDLYME can complete most jobs in just a few hours? 

With RYDLYME, there is no need for multiple and expensive products for a job that may involve various metals or materials throughout a system. Other descalers may be highly corrosive to certain metals and materials, thus requiring an entirely different product or products for the same job. Incorporating multiple products into a cleaning puts a great deal of responsibility on the service company and technicians to use the correct product(s) on a particular system to avoid damage, as well as additional expenditures for more products. Why even take the risk when you have one product in RYDLYME that is all-encompassing?

BUYER BEWARE! The term "effective" is fairly ambiguous

As previously mentioned, many other chemical descalers state that they are just as effective, if not more effective than RYDLYME. What does that really mean? There are other descalers that are "effective", but...
  • only on calcium carbonate, but not iron oxide
  • only at a high concentration (one product label even states to use at 100% concentration!)
  • may take a day or several days to completely, or even mostly, get rid of a deposit
  • only on certain pieces of equipment or metals and materials

You get the idea. Don't just rely on wordplay or general statements. Do your research by reading a product's SDS and label, as well as running bench tests on your own. A bench test does not have to be too complex or involved. Dropping a simple TUMS tablet into a small amount of product will show how fast a product will work. As a comparison, do the test with a few different descalers (including RYDLYME of course!) and compare times. Even try different dilution rates (e.g. 100%, 50%, etc.) to determine which products work better. Just remember to wear safety equipment when handling other chemical descalers other than RYDLYME (see the Health & Safety section below)!

Also, ask other professionals in your field about what products to use or what products to avoid. Heck, contact us at 800.451.6291 or 630.820.8888 and we can elaborate on any of the information provided!



The RYDLYME Advantage


The use of RYDLYME does not require special safety equipment or procedures because it is a non-hazardous and non-toxic descaler! There are no toxic fumes and you can even HOLD IT IN YOUR OPEN HAND WITHOUT INJURY! CLICK HERE to see proof! There are NO restrictions, special licenses or permits needed to transport or handle RYDLYMEReview Section 14 Transportation Information of each product's SDS to learn about restrictions.

What does this mean to you?

The safeness of RYDLYME quells any health and safety concerns when it comes to handling and transporting the product. You will have a much easier time introducing RYDLYME into any number of applications than with hazardous chemical descalers because there is no need for special hazmat equipment (e.g. respirator, suits), elevated temperatures or procedures (e.g. permits, special handling). Review Section 8 Exposure Controls/Personal Protection of each product's SDS to learn about protection.

Unlike other descalers, RYDLYME is 100% biodegradable WITHOUT neutralization! RYDLYME is certified by an EPA-approved testing facility as 100% biodegradable and environmentally non-hazardous at full concentration/as-received form. This means even at full concentration, RYDLYME is not only safe to handle, but also does not have a detrimental effect to the environment.

For example, an accidental spill at a facility with a container of RYDLYME does not necessitate special hazmat containment and disposal procedures, or even pose a safety or health concern to personnel or equipment. It can be safely disposed down a normal plant sewer or drain, followed by a thorough water flush and clean up is done. The same cannot be said about other descalers. Review Sections 12-13 Ecological Information and Disposal Considerations of each product's SDS to learn about biodegradability, environmental concerns and disposal.

BUYER BEWARE! Biodegradability does not equate to safeness 

Erroneously, many descalers equate biodegradability to safeness, but are actually highly hazardous and corrosive. Look closer at the label and SDS of other descalers and you will see that most of them are extremely hazardous and corrosive, requiring special safety equipment and procedures when handling and even transporting their products.
Some even base their safeness on the premise of being ODORLESS! This is an irrational claim considering carbon monoxide (CO) and hydrogen sulfide (H2S) are also odorless and cause serious illness or even death. Additionally, other "biodegradable" descalers must be FULLY neutralized to be even remotely biodegradable. Review Sections 12-13 Ecological Information and Disposal Considerations of each product's SDS to learn about biodegradability, environmental concerns and disposal.
