MAXX Ultra 321 prespray has been a staple for our customers for over a decade.  Ultra 321 is highly concentrated for cost-effective quality results on residential and light commercial carpet locations.  And with the Carpet And Rug Institue’s seal of approval, you can be sure not to leave residue behind.


MAXX Ultra 321 can be combined with other MAXX products such as Citra Boost or any of the MAXX water-based deodorizers like MAXX Mango.

This premium prespray is safe for use in standard pump sprayers or in-line / injection sprayers.  When using MAXX Ultra 321 in a Hydro-Force, add one quart of prespray and fill up the rest of the container with water for best results.

Additional Information

Always shake this product well before mixing with water or spraying.  We recommend allowing 5 – 15 minutes of dwell time after prespray is applied to carpet before extracting.  Hot water extraction is almost always best.  Remember to include MAXX Ultra Rinse or MAXX Ultra – X with your fresh water for enhanced performance.
