Acidic Cleaning Procedure

(For Equipment Used With Compressed Air)

Introduction

This procedure provides complete instructions for cleaning reusable, non-wearing components and parts of regulators and valves used with standard Grade E compressed air. Acidic Cleaning must also be per- formed as a prerequisite to performing Aqueous Cleaning — an addi- tional procedure that is necessary for cleaning component parts of equipment used with mixtures of oxygen enriched air (EAN/Nitrox) containing more than 24% oxygen.

Acidic cleaning is a five step procedure that includes:

▼Degreasing and pre-scrub, plastic parts cleaning

▼Tap water rinse

▼Ultrasonic acid bath

▼Sodium bicarbonate neutralizing bath

▼Distilled or de-mineralized water rinse

Required Equipment

❏Ultrasonic Cleaner – Essential to provide the most effective removal of corrosion and scale from metal parts. It is impossible to attain the same level of cleaning with any other method. Preferred features include a built-in timer and a heater.

❏Screen Dip Basket – Provided with most ultrasonic cleaners, allows the parts to be fully immersed in each solution, and trans- ferred from one container to the next.

❏Separate Containers – It is important to use four separate con- tainers, including the well of the ultrasonic cleaner, to hold each solution so that the parts can be transferred quickly in the correct sequence and with minimal delay. Each container should be ap- proximately the same shape and size as the well of the ultrasonic cleaner, so that the dip basket fits completely inside.
