Lather is designed for maintenance of your interior plastic, leather, and vinyl (old school). Spray it directly on the surface, agitate it with an Interior Brush until a “lather” is created. Then, immediately scoop away the white lather with a microfiber towel. Lather is similar to AMMO Spit in that you should always have it handy for regular basic maintenance. However, if you need a stronger or “more precise” interior cleaner for urine stains, vomit, poop, milk, etc… then you will need a different product = Dygest Pet Stain Remover. If you have coffee, tea, or juice stains, then Syphon Coffee+ cleaner contains the specific pH to remove those particular stains. My point is this, Lather is the perfect balance of maintenance and cleaning power for every week use, but if you have and oil stain (sweat) then use Titan degreaser, if you have organic stains (blood, vomit, etc…) then use Dygest, Coffee stain then Syphon.
