Frequently Asked Questions
Our most common questions are around old stain removal, how long does it take and is it safe to handle.
There are many stain types and environmental situations where Terminator-HSD (T-HSD) will successfully bio-remediate the problem. As T-HSD is a non-chemical product is requires moisture to remain active and effective. Initially T-HSD will draw on the moisture in the stain / spill to quickly multiply the oil munching microbes. T-HSD will continue to work until the unwanted compounds are remediated.
Removing old stains?
Yes, T-HSD concrete and asphalt cleaners will fully remove old stains. However, if the stain has been caked on with layers of oil and grease etc. The top layer will need to be chipped away allowing the microbes access to the pores of the concrete.
How long does it take?
Most stains, even very old ones, are fully remediated within four to six weeks. Some hydraulic fluid stains require additional time as to fully breakdown the hydrocarbon chains.
Is it safe to handle?
T-HSD is a seaweed based product with 4 strands of bacteria (3 are proprietary) bonded to the seaweed. When the microbes are finished with their work they leave a fine sand which is easily disposed. With a net positive environmental gain. See MSDS for PPE.
