Recommended Usage: General Hygiene. Avoid cross contamination with colour coded absorbent wipes for reuse in demanding applications or tackle the tougher tasks with the Livi heavy duty industrial spec turbo wipers. The Livi Blue commercial wipe has 90 sheets per roll and is perforated for controlled usage. HACCP certified, each non woven wipe is 70 grams per square metre making them thick and strong for extra absorbent results.
