58C101 - Walter Coolcut CNC Sump Cleaner and Biocide Flush 950ml

Deep Clean Your Machining Systems

The Walter Coolcut System Cleaner (58C101) is an essential maintenance chemical designed to restore hygiene and efficiency to CNC machines and metalworking fluid reservoirs. Over time, coolant tanks become breeding grounds for bacteria, fungi, and biomass. These contaminants not only cause foul odors—often described as the "Monday morning smell"—but they also degrade the performance of fresh coolant, clog lines, and can cause skin irritation for operators. Simply draining old coolant is often insufficient, as biofilm remains clinging to the walls of the sump and inside the piping system, ready to contaminate the new batch immediately.

Walter's advanced formula utilizes powerful biocidal agents to penetrate and eliminate these biological contaminants. By adding the Coolcut System Cleaner to your machine's tank 12 to 24 hours before a scheduled drain, you allow the solution to circulate through every pump, hose, and crevice while the machine continues to operate. This "clean-while-you-run" approach minimizes downtime while ensuring a thorough flush. Once the cycle is complete and the old fluid is drained, your machine is left with a pristine, decontaminated environment.

Using this 950ml system cleaner is a cost-effective strategy for any machine shop. By starting with a sterile sump, your new batch of coolant will resist degradation for much longer, extending drain intervals and reducing disposal costs. It effectively removes oil residues, sludge, and microbial growth that compromise machining precision and tool life. Whether you are running a large industrial milling center or a smaller lathe, the Walter Coolcut System Cleaner is the professional choice for fluid management and machine hygiene.
