You can clean most anything: kitchens (home and commercial), baths, carpets and carpet stains, vehicles (interior & exterior), floors, blood stains, glass, stainless steel, and all kinds of oil and grease. It makes a great whiteboard cleaner too, even for old residual marks.

How? Psst safely breaks down the bonds of dirt using molecular action (not enzymes) to restore surfaces to a pristine state.

Psst works best when given a little "dwell time" to do its job, especially on heavily soiled areas. Spray it on, give it a few seconds, then wipe off. Repeat as needed. It's safe on skin, so you don't need gloves.

For carpet stains, first test colour-fastness in a small hidden area. Spray Psst liberally on the affected area, wait about 10 seconds then dab the area with a clean cloth to begin to absorb it. Allow to dry (or partially dry) and reapply Psst as needed until the stain is gone.
