MEDAC is a combination of certain inorganic mineral acids with an inbuilt detergent system for brightening of stainless steel of medical instruments and equipment.

MEDAC Acidic Detergent is intended for use in the following operation:

Brightening of stainless steel instruments and utensils
Periodic brightening of stainless steel instruments and utensils in ultrasonic machines
Surface brightening of stainless steel benches and trolleys
Removal of scale and soil deposits in sterilizers, washer/disinfectors, ultrasonic machines, anaesthetic apparatus decontaminators, dishwashing machines and hot water soaking baths
Descaling plastic and glass utensils
Assists in the removal of surface rust

It is an efficient brightening and descaling compound and is free rinsing. This acidic detergent is designed for use in soft and hard water areas.

CAUTION: DO NOT USE ON CHROME, SILVER PLATED OR ANY OTHER PLATED INSTRUMENTS. AVOID USE ON ACID REACTIVE METALS SUCH AS COPPER, STEEL, ALUMINIUM, ZINC, ETC.

DIRECTIONS FOR USE:
1.  BRIGHTENING OF STAINLESS STEEL INSTRUMENTS AND UTENSILS - MANUAL METHOD
Preclean instruments with SONIDET or CLINIMAX.
Dilute MEDAC at a rate of 50mL per Litre of hot water (55 - 60°C) in a soaking tray, preferably plastic.
Immerse instruments and utensils for a period of 15 minutes (heavily solied instruments may require a  
30 minute immersion time).
Remove instruments or utensils from tray and rinse thoroughly.

2.  PERIODIC BRIGHTENING OF STAINLESS STEEL INSTRUMENTS AND UTENSILS - ULTRASONIC  METHOD
MEDAC should be added when the tank is filled with water at the rate of 5mL MEDAC per Litre of water.
The average size Ultrasonic Machine is 45 Litre capacity. This would require 225mL or for ease of 
measurements 250mL (1/4 of a Litre).
Follow normal cycle for ultrasonic machines ensuring that all articles are rinsed thoroughly. Heavily 
stained instrumnts may require further application.

3.  BRIGHTENING STAINLESS STEEL BENCHES AND TROLLEYS
Dilute MEDAC at the rate of 75mL per Litre of hot water (55-60°C).
Scrub thoroughly with a nylon brush and rinse thoroughly with water.

4.  REMOVAL OF SCALE & SOIL DEPOSITS FROM STERILISERS
Ensure that steam is turned off. Open doors and allow the steriliser to cool (Do not apply MEDAC solution 
to hot surfaces). dilute MEDAC at the rate of 10mL per Litre of hot water (50-60°C) and apply with a mop.
The surface should be maintained in a wet condition with the solution to allow MEDAC to penetrate and
loosen the scale or soil deposits.
Heavily scaled or soiled sterilisers may require higher dilutions and repeated applications. When all traces
of scale and soil have been removed the surface should be rinsed thoroughly with cold water and allowed
to dry. Rinse mop and allow to air dry.

5.  REMOVAL OF SCALE AND SOIL DEPOSITS FROM ULTRASONIC MACHINES, ANAESTHETIC   
MACHINES, WASHER/
DISINFECTORS, ANAESTHETIC APPARATUS DECONTAMINATORS, HOT WATER
SOAKING BATHS.
Turn off detergent dispensing system if fitted.
Drain machine.
Add a solution of 10mL of MEDAC per litre of hot water (55-60°C).
Start machine and allow normal cycle to operate. Heavily scaled or soiled machines may require more   
than one cycle or in some cases a higher concentration of MEDAC may be require more than one cycle or
in some cases a higher concentration of MEDAC may be required.
Ensure that the machines are well rinsed to remove any traces of MEDAC.

6. REMOVAL OF SCALE & SOIL DEPOSITS FROM DISHWASHING MACHINES
If machines are fitted with Electronic Detergent Dispensing Units ensure that switches are in OFF position.
Drain machine, refill and allow water to heat to a minimum of 60ºC. Add MEDAC at the rate of 10 mL      
per litre to wash tank. In continuous washers MEDAC should also be added to the wash and power rinse 
tanks. However, as all machines have varying capacities it is recommended that the manufacturer’s 
manual be referred to for accurate wash tank capacity. Start machine and allow to operate for 10 minutes.
Stop machine and observe results. In the case of heavily scaled or soiled machines a long handled nylon
brush may be employed to loosen heavy deposits. Restart machine and allow to operate for another     
5 minutes. Heavily scaled or soiled machines may require further applications or in some cases a higher
concentration.

Drain and rinse machine. Refill machine and switch on electronic dispensing units and commence normal
operation. To prevent future scale or soil deposits it is suggested that the following weekly maintenance
be followed. Switch off electronic detergent dispensing units and drain machine. Refill machine and allow
water to heat to 60°C.

Add MEDAC as follows:
TUNNEL WASHERS: 200mL MEDAC to wash tank and power rinse tank
UP-RIGHT WASHERS: 75mL MEDAC to wash tank. Start machine and allow operate for 10 minutes.

7.  DESCALING OF GLASS AND PLASTIC WARE
Rinse all articles under running water and drain.
Dilute MEDAC at the rate of 50 mL per litre of hot water. (50 - 60°C).
Allow to soak for 15 minutes. (Heavily soiled articles may require stronger solution and a longer soaking 
time).
Drain, rinse under running water and drain.
 8. MIELE PASTEURISING MACHINES
MEDAC is suitable for the neutralising operation in the Miele machine.
Add MEDAC undiluted to the acid neutraliser tank.
CAUTION:  IN  ALL  OPERATIONS  GLOVES  MUST  BE  WORN.  PROTECTIVE  EYEWARE  MUST  BE  USED.  WHEN
DESCALING STERILISER MASKS AND PROTECTIVE CLOTHING MUST ALSO BE USED.
