Glasscare Guide: Frequently Asked Questions Relating To Glass Care

Posted by Sara Malcom on

We aim to be as proactive as possible active in educating customers in the proper procedures required to achieve the best results from their glasswasher.

To emphasise the importance of regular maintenance, we conducted a controlled survey of 100 customers that actively follow our guidelines. The outcome is that problems relating to both machine efficiency and glass presentation dropped by over 44%.

In the latest instalment of our Glasscare Guide series, we’ve answered some of the most frequently asked questions we receive from customers about issues with their glasswasher and how to achieve the best results.

Q. My glasses don't seem to be drying properly after removing from the glasswasher. What can I do? 

Something is adhering to the glasses, thus keeping the water from drying off as normal.

It could be that staff are using a tea towel to finish glasses. If this has been washed using fabric conditioner, an oily film will be transmitted which will not necessarily be removed by the wash cycle.

The rinse cycle might not be generating sufficient water to remove all the detergent. If this is the case, a booster pump may be required.

A further basic cause of this is that detergent and/or rinse aid containers are not filled or are blocked.

Even when your glasswasher is functioning correctly, it can take up to 40 minutes for glasses to dry naturally. For busy sites with limited storage space this can result in a shortage of glasses at peak times. A simple solution to speed up glass turnaround time is to use an Air Rack Glass Dryer which reduces the drying time to just 4 minutes.

Q. Customers are complaining that their beer looks flat even though I know is nothing wrong with it. What could the problem be?

The solution could be as simple as changing your glassware. You may be using toughened glasses that have a smooth texture which is not conducive to achieving a good head to your beer.

Alternatively, your rinse aid and/or detergent dosage might be set too high meaning that residue is left in the glasses.

It could also be down to oils getting into the glasswasher from another source. See if staff are washing coffee cups with glasses (cream and milk might be present) or it could be grease from food.

Q. Why do glasswasher manufacturers charge more for their chemicals than my local cash and carry?

There is a significant difference in quality between cheaper chemicals sold at your local cash and carry and the premium chemicals sold by commercial dishwasher and glasswasher manufacturers. Cheap chemicals are highly caustic and, although may work initially, will quickly cause permanent damage to your dishwasher or glasswasher and glasses.

Commercial glasswasher manufacturers recommend their own brands because they can guarantee they will produce the best results on an ongoing basis.

Q. Why are there brownish deposits on some of my glasses despite washing them correctly?

This sounds like yeast build up. The problem lies with your glasswasher and is especially common on older style models with lots of bacteria harbouring nooks and crannies.

Yeast loves warm damp conditions so kill it off by leaving your glasswasher door open overnight. If this does not work, try increasing the detergent dose slightly.

Alternatively, you can use Refresh Renovating Detergent to remove all traces of yeast from both the glasses and the machine.

Q. My glasses have a cloudy appearance, they feel almost chalky to touch. What can I do?

This could be one of two reasons:

  1. Your glasswasher could be using excessive amounts of detergent and rinse causing a chemical build up. This could be remedied by adjusting the chemical dosage of your machine.

  2. There are excess minerals in the water supply which is causing scale to form on the glasses. The most effective solution is to fit a demineralisation cartridge, which is relatively costly so we recommend getting a second opinion before doing so.

Q. My glasses are fast being destroyed by my glasswasher. They have a scratchy, frosty appearance which seems to have penetrated the glasses.

This is etching – a natural process that happens to all glasses over time. However, you can slow the process down.

Make sure you are using high quality chemicals, that have been recommended by your glasswasher supplier. Etching can be aggravated by using cheap brands of glasswasher detergent and rinse aid which are highly caustic and eat into the glasses surface.

Try taking the glasses out of the glasswasher immediately after the cycle has finished as sitting in high temperatures will speed up the etching process.

The final solution would be to change your brand of glassware as some are more prone to etching than others.

Q. Is there anything I should be doing to ensure my glasswasher continues to provide good results?

Your glasswasher will only deliver good results if it is maintained to a high standard. We recommend following our Daily Maintenance Schedule which provides easy-to-follow instruction which, if followed correctly, will extend the lifespan of your machine and ensure it delivers sparkling results.

A few other factors to consider:

  • Use good quality detergents and rinse-aid. We recommend using our own range of premium chemicals as they have been formulated to deliver the best possible results when used with our Advantage Range and Speedwash Range

  • Regularly renovate your glassware. Our article Glasscare Guide: The Importance of Renovation, outlines the benefits regularly renovating your glassware.

  • Don’t use the glasswasher as a sink. Pouring in beer slops will neutralise the detergent and promote protein build up.

  • Don’t use the glasswasher as a rubbing bin. Debris such as fruit pips, peel, cigarette ends and cocktail sticks will clog filters and block the wash and rinse jets.
