POWER CLEAN CR21

POWER CLEAN CR21 cleans carbon deposits from engine components quickly and effectively — pistons, heads and combustion-area parts return bright from the bath. Typical applications are piston and head cleaning, carbonised residue removal and engine overhaul shops.

Compatibility is confirmed against your actual components before anything is recommended. As a rule, alkaline grades suit steel and cast iron, while aluminium, zinc, brass and mixed-metal baskets need a neutral-pH grade such as POWER CLEAN NF-14.

Power Clean aqueous concentrates work between 1% and 5% — that is 1:100 to 5:100 with water. Light maintenance soils sit at the low end; heavy machining oil, buffing compound and carbon need the upper end. The exact figure is set during the trial on your own parts.

55–65 °C for most aqueous grades. That is also where low-foam products stop foaming, because their surfactant clouds out just below the working range. A trichloroethylene vapour degreaser, by comparison, has to be held at 90–100 °C.

POWER CLEAN CR21 is intended for engine and piston cleaning use.

20 L, 50 L, 200 L and 1000 L, with custom packing available. Every product ships with a safety data sheet plus dosing and PPE guidance, and production runs to an ISO 9001 certified system with batch-wise quality control. Trials normally start with a single 20 L pail.
