A concentrate that turns any ultrasonic cleaner into a stronger one

A dilutable cleaning concentrate, mixed up to 1:30 with water, for lenses, jewellery, dentures and precision parts run through any ultrasonic tank.

Octopus concentrate is the detail plain water leaves out — ultrasonic cavitation does the mechanical work of loosening dirt, but a proper cleaning solution breaks down grease and oils that water alone struggles with, in any ultrasonic cleaner, not just Sonique models.

About this cleaning accessories

Octopus Special Ultrasonic Cleaner Concentrate

Every cleaner in this catalogue runs on plain tap water out of the box, and for light daily buildup that's genuinely enough. Octopus concentrate is for the step up: a proper detergent formulated for ultrasonic use, breaking down the grease, oils and heavier grime that cavitation alone works harder to shift.

It's dilutable up to 1:30 with water depending on how soiled the item is, so a single 250ml bottle covers a large number of cycles rather than being a one-and-done bottle, and it works in any ultrasonic cleaner, not just the models sold here.

At £16.50, it's a low-cost way to noticeably improve results on anything that's gone past a light daily clean, spectacles, jewellery, dentures, watches or small precision parts, without needing a different bottle for each item type.

Frequently Asked Questions

Do I need this, or does water work on its own?

Plain water and ultrasonic cavitation handle light daily buildup fine. This concentrate is for heavier grease, oil or grime where a proper detergent formulated for ultrasonic use gets noticeably better results.

How much do I use per cycle?

It dilutes up to 1:30 with water depending on soil level — start weaker for light cleaning and stronger for heavier grime, following the ratio on the bottle.

Is it safe for precious metals?

Yes, at the recommended dilution it is formulated to be gentle on precious metals and plastics while still being effective on grease and dirt.

Will it work in any ultrasonic cleaner, not just ones from this site?

Yes — it's a general-purpose ultrasonic cleaning concentrate, not tied to any specific brand or model of cleaner.

How long does one bottle last?

At a 1:30 dilution ratio, a single 250ml bottle stretches across a large number of cycles rather than needing frequent repurchase.

What does delivery cost and how long does it take?

Delivery cost and an estimated timescale for your address are calculated at checkout, before you pay. Free UK delivery applies over the qualifying order value.

Can I return this if it is not right for me?

Yes — return it unused, with the original packaging where possible, under our returns policy for an exchange or refund.

The complete guide

When plain water stops being enough

3 min read Sonique

Ultrasonic cavitation does the mechanical work regardless of what's in the tank, bubbles collapsing against a surface and physically dislodging what's on it. What water alone doesn't do well is break down grease, oils and certain organic residues at a chemical level, which is where a formulated concentrate earns its keep. If items are coming out of a plain-water cycle still looking dull or greasy rather than genuinely clean, that's the signal to add a proper solution rather than running a longer cycle on water alone.
