RYDLYME has saved companies millions of dollars in operational costs and downtime for over 78 years.

Simple & Effective​

Just dilute RYDLYME with water and it is ready to go. You will start to see results within minutes.

Water scale, lime, mud and rust deposits are a serious problem for virtually all industries who use water as an integral part of their manufacturing and heating/cooling processes. Once the water-based equipment or systems become fouled with scale, efficiency decreases, energy costs increase and the useful life of equipment is diminished. Failure to address water scale problems in a timely manner runs the serious risk of costly equipment or system shutdowns, repairs, or even replacement. RYDLYME is the safest, most simple and economical solution to your scale, rust or lime problem, keeping your equipment operating with maximum efficiency.

What our Customers say

"It pays for itself in weeks"

My company was struggling with declining efficiency in our heat exchangers due to rust buildup. We used Rydlyme for the first time in 2014 and after flushing for 1 day our equipment was running like new again. We now use Rydlyme for all our maintenance, saving us thousands per year, it pays for itself within weeks!
