HumminGuru FAQs

About the Cleaner 

Will the cleaner be compatible with 110v?

Yes, the HumminGuru cleaner supports all commonly used voltage standards from 100v-240v. 

Does it support 180g and 220g records?

Yes, the HumminGuru cleaner supports 180g and 220g vinyl records.

Can we clean the 78’ shellac record with HumminGuru Cleaner?

We do not recommend cleaning 78’ shellac record with ultrasonic cleaning machine due to the fragility of the record type. If there is minor crack on the 78’ shellac record, the ultrasonic bath may damage it further.

Is there a rinse cycle? 

There is no rinse cycle in the cleaner and thus we recommend users using distilled water for the cleaner. 

Does the HumminGuru cleaner blow hot air onto the record?

No, there is no heating system in the cleaner. 

How does it prevent external dust from blowing back onto the record?

The HumminGuru cleaner comes with the washable and replaceable air filter which is installed under the side panel of the machine to trap external particles occurred during the drying cycle. It is recommended to rinse the air filter with water on a regular basis and air dry completely before use. Check the wearing status. Replace it with a new filter when it starts to wear out. 

Is 40 kHz ultrasonic system sufficient? 

Applying a duo 40kHz ultrasonic system in the HumminGuru cleaner is powerful enough to remove the contaminants and dust on the vinyl record without causing damage. 

Will the paper label on the record get wet during the cleaning cycle? 

No, the paper label on the record will not get wet during the washing cycle as long as users do NOT overfill the water basin with distilled water based on the record size. Please follow the water level indication for 12” and 7”/10" records on the removable water thank. We recommend users double checking the water level with the maintenance tool that comes with the HumminGuru cleaner. Notice: The water level guide is for your reference only. The optimal water level should be based on the distance from the edge of your record to the water level that is slightly above the outer ring of the dead wax area. Caution: DO NOT fill the water tank with water to a level exceeding 400ml. Failing to do so may result in water spill or leakage. 

What water temperature do you recommend for optimal cleaning results?

We recommend using warm distilled water between 25˚C to 35˚C that would enhance the surface tension effect for optimal cleaning results. Avoid adding water over 35˚C at the beginning of a cleaning cycle. Please keep in mind that the water temperature will slightly increase due to the nature of ultrasonic technology.

Any advices for cleaning a very dirty record?

For users who would like to deep clean the record, please re-apply the 5 mins quick cleaning mode to clean as much as you need to, and then select the Auto Deep Cleaning mode to clean and dry the record for the last step.

My record does not get completely dry even after 10 minutes of drying.

Whether the record gets completely dry or not is subject to the condition of the vinyl record, the room temperature, and the relative humidity of the environment. If the setting II (10 mins) drying does not completely dry your records, please simply re-apply 5 mins/10 mins drying-only mode.

Will the water drainage operate only when the removable water tank is set in place?

Yes. Please ensure that you put the water tank with the lid back into the slot properly before starting the water-draining process.

Can I use an isopropanol mix or wetting agent with the HumminGuru Cleaner?

We recommend distilled water for the optimal cleaning result. It is up to our user’s choice and responsibility for taking the risks of product damage by applying any cleaning agents or fluids. Any damage result from using other solutions will void the warranty. Reminder: Avoid using corrosive or flammable fluids. 

Is it okay to use tap water or demineralized / de-ionized water for the machine?

We recommend using distilled water which is purified by boiling and re-condensing in the HumminGuru cleaner for the best cleaning result. We do not recommend using tap water as the limescale in tap water may leave residue on the pipes of the HumminGuru cleaner. However, it’s up to the hardness of water in your region and thus please make your own judgment when using tap water at the user’s own responsibility. Even though demineralized / de-ionized water is indicated that (most of) its mineral content and salt ions removed, the remaining particles would have the possibility to get stuck in between the grooves and may also leave residue on the pipes of the HumminGuru cleaner in long-term usage. Please make your own judgment when using demi-water at the user’s own responsibility. 

Can I reuse the distilled water? After how many cleaning cycles do you recommend?

Yes, you can reuse the water until you obverse the water is visibly dirty. It depends on the condition of your records and please make you own judgement. The washable and replaceable water filter is installed in the water tank to filter out large residue from the water during the cleaning cycle. It is recommended to rinse the filter with water on a regular basis and air dry completely before use. Check the wearing status. Replace it with a new filter when it starts to get dirty or wear out. 

Does HumminGuru cleaner acquire any certification?

Yes. The HumminGuru has obtained CE, FCC and Rohs certification. 

Why does the machine not turn on even I pressed the power button? 

Please press the power button all the way until you hear a lick sound for the machine to properly turn on. 

Will the cleaner be compatible with 110v?

We do not suggest users to use aluminum foil to test with any ultrasonic cleaning machine. When the ultrasonic wave hits the foil, it will more/less dissolve the foil and create powder-like material. Such powder will sink to the bottom of the water basin and eventually increase the chance of clogging the tube of the draining system. Moreover, if it does not get cleaned thoroughly, it might affect the cleaning performance or induce damage on the record groove.
