# How do you recommend safely dispose of the M1 Sample Prep cartridges and reagents?

**DO NOT add bleach or acidic solutions directly to the liquids contained in [Biomeme's M1 Sample Prep cartridges](https://shop.biomeme.com/sample-prep/)**. The **BLB** (Biomeme Lysis Buffers) and **BPW** (Biomeme Protein Wash) buffers contain **guanidine salts**, which can form **highly reactive compounds when combined with sodium hypochlorite (a.k.a. liquid bleach).**

If liquid containing these buffers is spilled, clean with suitable laboratory detergent and water, or 70% alcohol.

If the spilled liquid contains potentially infectious agents, clean the affected area multiple times with laboratory detergent and water. Then, clean the area with 1% (v/v) sodium hypochlorite.
