# Can I use a rinsed chemical or fertilizer tanks to store DEF?

## No... and here's why...

No. DEF is an ultra-clean fluid that needs to be kept clean so you do not harm the SCR system. Using an existing fertilizer or chemical tank would result in these residues being transferred into the DEF tank and the result could destroy the SCR System on the implement.
