Filter Free is a water-based d-limonene emulsion designed to remove filtration soils around heat resisters, along walls and doorways. Apply full strength, agitate, allow to dwell for five minutes and rinse. On very difficult filtration soils rinse with high heat to accelerate the process.

Filter Free is also a great oil and grease spot remover. On top of it all, Filter Free has a wonderful orange smell and is in compliance with VOC limits.
