Helpful Tips Icon


High quality chemicals are essential for cleaning and drying glasses and tableware, they are also essential for renovating glasses and for looking after your glasswasher/dishwasher. Chemicals play an important part in the overall processes of achieving perfect results.

Did you know? Good quality chemicals are formulated to cope with high levels of tannins, proteins and water hardness, and they aid the drying process by shedding as much excess water from the glass as possible and preventing ‘spotting’.

Clenaware Systems Chemical Header

Why You Should Use High Quality Chemicals


  • A high quality Detergent is formulated to cope with high levels of tannins, proteins and water hardness.
  • Less likely to leave residue on your glasses.
  • A low quality Detergent will not clean your glassware. You may find you still have tannins and proteins on the glass making them look dirty and unsightly.


  • A high quality Rinseaid will aid in the drying process by shedding as much excess water from the glass as possible, helping to prevent spotting.
  • The Rinseaid we recommend will not ‘froth’ in the Header Tank, unlike other Rinseaids on the market. If you use a lower quality Rinseaid then you may find your machine becomes intermittent and inoperable. This intermittent problem can be due to the Rinseaid frothing in the Header Tank triggering the Float Switch and causing the machine to cut out during the cycle.


  • Renovating your glassware is essential for removing the manufacturers film on any new glassware.
  • Renovating your glassware can help to remove any mineral deposits on the glasses that build up with use over time.
  • A low quality Renovate could leave a film on the glass and may cause the beer to go flat.

Chemicals play an important part in the overall process of achieving perfect results.

Water Treatments

Over time, fat deposits (fog), limescale and other minerals can begin to build-up on the surfaces of your glass/tableware. This isn’t just unsightly, it’s also another factor preventing the delivery of perfect results. Contaminates and scale found in water can’t always be removed, and these contaminates will ultimately flatten and effect the appearance of drinks. Water treatments are not only beneficial, they are also necessary for delivering perfect results.

How To Spot When Your Calcium Treatment Unit Needs An Exchange

  • Wash Results - You will notice spotting or a milky type residue on the glasses after they have been washed in the glasswasher.
  • Wash / Rinse Arms - The black plastic of the arms begin to look grey and chalky.
  • Wash / Rinse Jets - The small holes in the Wash and Rinse Jets become blocked with limescale and will usually cause issues with the rotation of the arm and cause the rotation light to be red.
  • Draining - If there is extra water in the machine and it isn’t draining fully, it is most likely that the Filters inside the Wash Tank are full of limescale or debris, or the Outlet Hose or Drain Pump is full of limescale or debris. If the machine is constantly trying to drain it is likely the Spindles piston (located in the Wash Tank under the Wash Arm) is stuck up due to limescale. This can be resolved by using descaler but can also indicate the CTU is ready for exchange.
  • Beer Presentation - The beer isn’t retaining its head, or the beer tastes flat. This usually indicates either limescale build up on the glass or can be chemical residue clinging to the limescale build up on the glass.


With many different styles of glassware in constant use, ensuring you choose the right basket to wash them in is more important than ever. Baskets now come in a range of different sizes and styles, which have been designed specifically with each individual style of glassware in mind.

Did you know? wider spaces between the wirework ensures that the water from the wash and rinse jets have a larger area to get through. This ensures that the glasses are washed and rinsed more thoroughly. This means there’s no escape for grease and dirt!

Tips To Help Prevent Breakdowns And Unnecessary Call Outs

  • Follow the daily cleaning maintenance schedule as listed on the Care Card. Unnecessary dirt build up can cause issues with the working of the machine, such as dirt build up around the Door Frame. This can stop the machine Door Switch activating leading you to believe the machine isn’t working.
  • At the end of the working session allow the machine to fully closedown when you select the closedown cycle. Once the cycle is fully finished isolate the power to the machine. If you prematurely switch off the machine, the next time you go to use it the machine won’t start up correctly.
  • In the colder winter months, the water coming into the machine will take longer to heat. So, at the start of the working session have a little patience and DO NOT press any buttons whilst waiting for the machine to heat. If you do press buttons unnecessarily this will ‘confuse’ the machine and it won’t fully operate, leading you to believe the machine has broken down.
  • If you have any glass breakages in the machine, ensure that all of the glass is removed and make sure all of the Wash Tank Filters are firmly in place as these prevent broken glass from getting into the Pumps.
  • Use good quality chemicals in the machine, this not only gives you better wash results but also helps to keep the machine clean. It also stops the detergent and rinseaid indicator lights on the Control Panel from going orange, which can lead you to believe the chemicals aren’t dosing properly.
  • If you’re in a hard water area fitting a water treatment to the machine will prevent breakdowns that can result from limescale build up inside the machine. Parts such as heating elements and hoses can get ‘caked’ with limescale and become less efficient.
  • If you have done all of the above then the Technical Support Team will be available to diagnose over the phone and if required they will book an engineer visit to site.

Tips To Keep Your Machine Running Efficiently Between Services

  • Follow the maintenance schedule every day, remove Wash Arms, Rinse Arms and the Filters and clean them.
  • If you want to keep the interior of the machine clean, use Renovate powder once a week to clean the Wash Tank. Use one scoop of powder and then select a wash cycle without any glasses in the glass basket.
  • Invest in a Clenaware Machine Cleaning Kit which contains brushes designed specifically for cleaning inside the Wash and Rinse Arms and machine. The Cabinet Brush in the kit is ideal for sweeping out any dirt from inside the tank.
  • Take a clean damp cloth and wipe it around the door sill to free up any build up of sludge that can be caused by moisture from the machine and chemical residue.
  • If you have a manual water softener fitted to the machine, ensure that this is salted and regenerated at least once a week to keep on top of unsightly and harmful limescale build up.
  • Close your machine down fully each day at the end of a session and ensure you leave the door ajar slightly so that the machine interior is allowed to ‘breathe’ to prevent a musty smell coming from the machine and transferring onto your glassware.
Clenaware Systems Airack Header

The Airack Glass Dryer

Do away with tea towels and simply place your glass basket onto the Airack glass dryer and let it work its magic. By using the Airack Glass Dryer, glasses dry 10 times faster which allows you to use them quickly and pour the perfect pint!

Did you know? After being washed, glasses take up to 40 minutes to dry on a ventilated shelf. On the Airack they take as little as 4 minutes! There is no other product like it, why? Because we invented the idea!

Tips For Looking After And Using Your Airack

  • Follow the daily maintenance as per the Care Card enclosed with the Airack.
  • Make sure you site the Airack correctly as per the Installation Card enclosed with the Airack.
  • When the Airack is not in use, disconnect it from the mains supply and remove the Top Cover from the base for cleaning.
  • Only clean the Top Cover of the Airack with a clean, damp cloth. Pay attention to the air holes in case of any blockages from water residue, that may otherwise restrict the airflow when the Airack is in use.
  • For best results use your Airack with a wire basket as these have bigger clearance holes allowing the air to circulate more freely.

Basket Units

The correct storage of your glass and tableware contributes to the achievement of a perfect result and makes the results safer and more hygienic.

Accessories and Cleaning Items

Cleaning and caring for your warewasher is as important as cleaning the glasses and crockery that goes into it. Keeping the warewasher clean will assist in prolonging the life of the machine and eliminates the chance of any debis attaching itself to otherwise clean items.

How To Care For Your Warewasher

Wash Tank Cleaning

  • With all Filters and Spraybars in place, wipe-down all interior surfaces using a damp cloth and use the Cabinet Brush to remove any stubborn stains or debris.
  • Use the Cabinet Brush to clean the frame and door labyrinth channels. Check also for any buildup of debris on the underside of the base of the door.

Wash & Rinse Spray-Bar Cleaning

  • Remove the top and bottom (dependant on model) Spray-bars by unscrewing their central retaining thumb nuts anti-clockwise.
  • Use the Cabinet Brush to clean the mating labyrinths of the wash-tank and spray-bar(s). These must be clean to ensure correct spray-bar rotation during washing and rinsing.
  • Remove the wash and rinse jets from the spray-bars by unclipping from the arms. Take care to keep the Sealing O-Rings.
  • Use the Spray-bar Brush to clean the inside of each arm by inserting the brush into outermost jet hole and then agitate the brush to scrub the inside surfaces. Following this, flush the arms clear with running water.
  • Use the Jet Cleaning Tool to remove any blockages or debris from the wash and rinse jet holes. Take care not to damage the jet holes. Following this, flush the jets clear with running water.

Filter Cleaning

Use the Cabinet Brush to clean all the wash-tank filters:

  • Remove the Main Tray Filter which covers the wash tank trough. Tip away any large debris or glass and brush under running water until the mesh is clean.
  • Remove the Secondary Drum Filter which unclips from the Wash Outlet Filter. Brush clean under running water to ensure that all particles and fibres are removed.
  • Use a damp cloth to carefully clean the wash tank trough interior.
  • Unscrew and remove the Wash and Drain Outlet Filters and brush clean under running water.


  • All Filters are in their correct positions.
  • The Wash and Rinse Jets are correctly fitted with O-Rings in place.
  • The Wash and Rinse Arms rotate freely.
