Q: Can an ultrasonic cleaner be used to sterilize jewelry?

A: Ultrasonic cleaners are primarily used for the purpose of cleaning items, not sterilizing them. However, a sterilizing solution can be used in combination with an ultrasonic cleaner in order to properly sterilize items. iSonic does not provide a specific solution for this purpose, so you must purchase one from an outside source.



Q: Do iSonic Ultrasonic Cleaners run on batteries?

A: In order to achieve a true ultrasonic frequency, all iSonic Ultrasonic Cleaners use AC power. Any company attempting to sell an ultrasonic cleaner, which operates via battery power, is making a false claim about the functional capacity of the product.



Q: Can an ultrasonic cleaner clean silver?

A: Yes, absolutely. If your silver is tarnished, try using our iSonic Silver Tarnish Remover.



Q: Do iSonic ultrasonic cleaners come with cleaning solution?

A: Some, but not all of our iSonic Ultrasonic Cleaners come with a 1oz. sample of our iSonic Jewelry and Eyewear Cleaning Solution Concentrate, iSonic White Denture Cleaning Powder, or iSonic Dualzyme Enzymatic Tablets. If you're looking to use more than just a sample size of the iSonic Cleaning Solutions, you can purchase any of our solutions on the iSonic Cleaning Solutions product page.



Q: Are ultrasonic cleaners safe for sterling rings with turquoise, agate, or onyx stones?

A: Solid metal usually cleans well in an ultrasonic cleaner. Soft stones, oil treated and color treated stones are not recommended for use in an ultrasonic cleaner. Soft stones are not structurally strong and may have internal cracks, which will not allow them to stand up well against the ultrasonic cleaner's high frequency. For these reasons, turquoise is not recommended; however, agate and onyx should be ok if there are not cracks in the stone.



Q: Will ultrasonic cleaning remove the green gunk that often forms on cheap sterling silver?

A: Yes, it should. However, if your sterling silver has tarnish, regular ultrasonic cleaning solutions will not remove the tarnish. Try using iSonic Ultrasonic Tarnish Remover to fully restore the sterling silver.



Q: Can I clean jewelry in the F3900 Denture Cleaner?

A: Yes. The plastic tray provided with the F3900 is supplied to prevent scratching when cleaning jewelry. It is important to thoroughly clean the F3900's tank after cleaning jewelry, so be sure to keep that in mind.



Q: Which ultrasonic cleaner is best for steeping e-liquid?

A: Steeping e-liquid cannot be done in one of our personal ultrasonic cleaners. We recommend using the iSonic P4810 or another larger, professional ultrasonic cleaner. The personal models do not include a cooling fan, and thus cannot run for long periods of time without overheating. The P4810 can run for 30 minutes continuously without overheating; however, be sure to allow your cleaner to cool for about 10 minutes between every 30 minute cycle. The larger, professional ultrasonic cleaners provided by iSonic are also made with stacked transducers, which are twice as powerful compared to the wafer transducers found in the small personal models.



Q: Does the heater have an automatic shut-off feature?

A: Yes, all iSonic Ultrasonic Cleaners featuring a heater turn off automatically upon reaching 140F/60C. As a safety feature, the heater also turns off automatically after 45 minutes.



Q: Do the personal models, such as the CD-2800, heat the water in the ultrasonic cleaner's tank?

A: If you need a heater, you may try the larger, professional models such as the iSonic P4810. In addition to including a heater, this model also has a larger tank size and a stronger, more powerful transducer. The smaller models will raise the temperature of the water in the ultrasonic cleaner's tank by a few degrees, but they do not include a heater as an extra feature.



Q: Can I clean diamond jewelry in an iSonic Ultrasonic Cleaner?

A: Yes. Diamonds show amazing results after an ultrasonic cleaning. Gold, silver and other solid metals, as well as hard stones, eyeglasses, sunglasses, diver's watches, watch bands, and small engine parts all show amazing results when cleaned in iSonic Ultrasonic Cleaners, just to name a few.



Q: How do I drain the P4820?

A: Pour the water out over one of the unit's corners. iSonic's larger, professsional models have built in drains. For example, the P4831 comes with a built in drain.



Q: Is the P4820 suitable for use in a laboratory? For example, to sonicate in glass vials while heating at 45C for 45 minutes.

A: Yes, the P4820 is suitable for this purpose, and it can be used in a laboratory setting. The temperature for the heater is preset at 65C and the heater turns off once it reaches this set temperature. iSonic provides several larger models with 5 temperature settings suitable for labs with 40-60C with a 30-minute timer. These are the P4831 models, the P4862, and the P4875 models.



Q: Can I use Efferdent Tablets in the F3900 Denture Cleaner?

A: Yes, you can use different denture tables or solutions as long as they are not too corrosive. Common Denture tablets are much less effective than iSonic White Denture Cleaning Powder, which is able to thoroughly remove stains and buildup from dentures. You can remove stains in less than 15 minutes with iSonic White in full strength in combination with the F3900 Denture Cleaner.



Q: Can I use an ultrasonic cleaner to clean my plastic dental retainer?

A: Yes; however, if your dental appliances have stains or buildups, tap water alone will not be able to remove them. We recommend using cleaning powder, solution, or a tablet. For example, iSonic White Denture Cleaning Powder is great for removing buildup and stains.



Q: Can I use the small iSonic Personal Ultrasonic Cleaners to clean coins?

A: Yes, but only clean a few coins at a time. If you need to clean large quantities of coins, try using one of the larger models, such as the iSonic P4810. Not only does this model have a larger tank size, but it also has a powerful and more durable transducer.



Q: How many cycles can I use the iSonic Jewelry and Eyewear Cleaning Solution Concentrate for cleaning eyeglasses?

A: At least 10 cycles. Once the water is too dirty, you probably do not want to continue to use the same solution, although it may still be effective. The solution is a concentrate, be sure to dilute it with water (about 1 capful to 2 cups of water).



Q: Is the iSonic F3900 safe for soft liners?

A: Yes the iSonic F3900 can be used to clean soft liners, provided the soft liners have solid bonding. However, you should not use denture tablets or iSonic White Denture Cleaning Powder to clean soft liners. Instead, use tap water or a small amount of mouth wash when cleaning soft liners in any iSonic device.



Q: Can I use an ultrasonic cleaner to clean silverware? Should I use a heater for this purpose?

A: Yes, you can definitely clean silverware in an ultrasonic cleaner. We recommend using one of our professional models such as the P4820 or larger. You may use the heater function as well, to achieve better results. If you need to remove silver tarnish from silverware, you must use iSonic Ultrasonic Silver Tarnish Remover to do so. We also recommend using a beaker or a plastic cup when using iSonic Ultrasonic Silver Tarnish Remover in any of our ultrasonic cleaners, as this particular solution will create a dull coating on the cleaner's stainless steel tank.



Q: Can I use a mason jar in place of a glass beaker when cleaning items in my ultrasonic cleaner?

A: iSonic does not recommend using a mason jar in place of a glass beaker as it can dampen the ultrasonic frequency and prevent you from achieving satisfactory results. A glass beaker is thin enough to allow the ultrasonic frequency to penetrate with enough strength to thoroughly clean your item. A thin plastic cup will also suffice. Ideally, you want to use a beaker holder as well, so as to prevent the weight of the beaker from effecting the performace of the ultrasonic cleaner's transducer. By placing the beaker directly into the tank, without a beaker holder, the beaker is sitting directly on top of the transducer and will prevent the transducer from providing optimal performance. iSonic provides several beaker holding attachments, which work with a variety of the larger models.
