FAQs

How long can I leave CLR Grease-Free on a stain before rinsing?

Grease-Free should only be left on a surface 1-5 minutes then rinsed off with cool clean water. If the stain persists, repeat the process.

How do I use CLR Grease-Free?

To use Grease-Free, sweep the area clean of heavy dirt and dust. For stains such as tar or heavy grease, scrape off as much as possible with a putty knife before cleaning. While wearing household rubber gloves, test a small, hidden area of the surface first before cleaning the main area. Pour or brush full strength to an area no larger than 12" x 12". Depending on size and difficulty of the stain, let the solution soak for one to five minutes. Clean the area with a clean brush or broom until the stain is loosened. Rinse at once with cool, clean water. Repeat the process if necessary. Do not use CLR Grease-Free with any other cleaners, bleaches or acids. If cleaning near grass or shrubs, rinse the grass and shrubs before and after cleaning.

What will happen if I leave CLR Grease-Free on too long?

If Grease-Free is left on too long and begins to dry, it can be very difficult to remove.
