Summer Concrete Cleanup Time

June 4, 2025

Concrete Cleanup - Cortec Corporation

Good weather is back in the northern hemisphere! As we spend more time outdoors, it’s easier to notice all the ugly stains on concrete driveways and sidewalks that may have been hidden by snow all winter. Rather than wait until the end of the summer to tidy up, now is the perfect time to start cleaning up with Cortec® MCI®-2061 or 2062 (two probiotic cleaners that skip the harsh alternatives) and leave yourself plenty of time to enjoy the results!

What Type of Stain Do I Have?

Before choosing a probiotic cleaner, it’s important to identify what type of stain you have. A vehicle oil leak is hydrocarbon-based and will match the probiotics of MCI®-2061. Food stains around a dumpster will require the probiotics and enzymes of MCI®-2062 that prefer consuming organic-based waste. Initial cleaning action comes from biodegradable surfactants that lift and disperse the waste. Microorganisms/enzymes continue the process by digesting the waste for deep cleaning.

How to Apply Probiotic Cleaners

MCI®-2061/MCI®-2062 should be diluted in water, applied, and worked into the pavement pore structure using a broom. It is important to leave the solution to sit one minute to one hour (or overnight, if needed) to give the microorganisms time to work before spraying off the surfaces with water. After rinsing, the probiotics will continue to provide residual cleanup on the hard surface as well as downstream in drains and sewers. Additional applications can be done as needed, and it is not unusual for the stain to continue to fade as time goes on!
