20-year rust and scale, cleared in 30 minutes
CLR ran for 36 hours and failed. VertKleen HCR cleared the same rust and scale in half an hour, verified by DDC Engineering (David DaSilva, PE).

Carib Brewery (CBUSA) lab evaluation, HCR versus the conventional CIP acid. HCR matched the clean at less than half the concentration and left no nitrogen or phosphorus in the effluent.
| Measure | VertKleen HCR | CIP acid (replaced) |
|---|---|---|
| pH | 1.0 | <1 |
| Sample concentration | 7% | 15% |
| Nitrogen (mg/L) | 0 | 33,300 |
| Phosphorus (mg/L) | 0 | 48,950 |
| COD (mg/L) | 0 | 0 |
Rust-removal test: on four sections of one rusted heat-exchanger plate, HCR removed the rust completely without effort while the in-use CIP acid left rust behind under more scrubbing. Source: Carib Brewery (CBUSA) lab results.
