Sensor Clean vs VDust Plus vs Smear Away: Which Wet Cleaning Liquid?

Compare Visible Dust's three wet cleaning liquids on supplied facts: Sensor Clean, VDust Plus and Smear Away. Learn which one to reach for first and when to switch.
Quick answer
Start with Sensor Clean for routine wet cleaning. Reach for VDust Plus when you need a stronger clean on stubborn marks, and use Smear Away when you are chasing streaks or smears left behind. The three liquids are not interchangeable in one pass; they are a sequence you pick from based on what you see on the sensor.
What each liquid is actually for
Sensor Clean is the everyday wet cleaning liquid. It is the one you use when a blower and brush have removed loose dust but a faint mark remains. VDust Plus is formulated for tougher contamination, and Smear Away is designed to remove smears and streaks that other liquids can leave behind. The practical difference is not brand preference; it is what is on the sensor and what the previous pass left behind.
The mistake that makes people switch liquids too soon
Most failed wet cleans are not a liquid problem. They are a swab-size or technique problem. If the swab is too narrow for the sensor, you drag contamination instead of lifting it, and then you blame the liquid. Match the swab to the sensor format first, then choose the liquid. A 1.0x swab for full frame, a 1.3x swab for Micro Four Thirds, and the 1.6x swab in the EZ Kit for APS-C are the correct pairings on the supplied product records.
How to choose between them in practice
If this is a routine clean and the sensor only shows a light haze, use Sensor Clean. If you have already done one wet pass and a stubborn mark remains, switch to VDust Plus for that spot rather than repeating the same liquid. If the sensor looks clean but the image shows a smear or uneven sheen, Smear Away is the targeted fix. One pass with the right liquid beats three passes with the wrong one.
What the supplied product facts tell you
The VisibleDust swabs in this range share a patented V shape and mini-channels that spread liquid evenly across the swab surface. That matters because an unevenly saturated swab is a common cause of streaks, and streaks are exactly what sends people looking for a different liquid. The fabric folding system is also designed to avoid leaving streaks, pooling or abrasions, so the swab and the liquid are doing two different jobs.
Trade-offs of each liquid
- Sensor Clean: Best first choice for routine wet cleaning and light contamination. It is the least aggressive option, so it is the safest starting point when you are not sure what is on the sensor. Use it first; only move on if a mark survives the pass.
- VDust Plus: A stronger option for stubborn marks that survive a routine clean. The trade-off is that it is not the liquid to reach for when the sensor is already clean, because you are adding a stronger step for no reason. Reserve it for marks that Sensor Clean did not lift.
- Smear Away: Targeted at smears and streaks rather than dust. The trade-off is that it solves a finish problem, not a contamination problem, so it will not help if the sensor still has grit on it. Use it after the sensor is clean but the image still shows a smear.
Products that use these liquids
- VisibleDust Green Ultra MXD-100 1.3x Vswabs (50 Pack): VisibleDust Green Ultra MXD-100 1.3x Vswabs (50 Pack) are tailored specifically to remove dust and use patented mini-channels with contour for even saturation of the swab surface. A 50-pack suits Micro Four Thirds shooters who clean often, and even saturation reduces the chance of streaks that would otherwise send you hunting for a different liquid.
- VisibleDust DHAP Orange 1.3x Vswabs (12 Pack) with bonus CurVswab and Corner Swabs: VisibleDust DHAP Orange 1.3x Vswabs (12 Pack) use double layer high absorbency fabric made of super-thin fibers, ideal for cleaning a delicate sensor without leaving streaks, pooling or abrasion, and include a bonus CurVswab and Corner Swabs. The high-absorbency fabric is a practical match for wet cleaning with Sensor Clean or VDust Plus, and the corner swabs help you reach edges a full-width swab can miss.
- VisibleDust DHAP Orange 1.0x Vswabs (12 Pack) with bonus CurVswab and Corner Swabs: VisibleDust DHAP Orange 1.0x Vswabs (12 Pack) use the same double layer high absorbency fabric and include a bonus CurVswab and Corner Swabs, sized for full frame. Full frame users get the same streak-resistant fabric in the correct width, so the liquid choice stays the only variable you are changing.
- VisibleDust EZ Sensor Cleaning Kit PLUS with Smear Away, 5 x Green 1.6x Vswabs and Sensor Brush: VisibleDust EZ Sensor Cleaning Kit PLUS includes Smear Away, 5 x Green 1.6x Vswabs and a Sensor Brush, and removes stubborn stains such as oil and lubricant while providing an anti-static barrier to reduce further contamination. This is the most direct way to try Smear Away without buying it separately, and the anti-static barrier helps keep the sensor clean for longer after the wet pass.
Which liquid fits your situation
Best for
- Routine wet cleaning when you want the least aggressive starting point
- Micro Four Thirds, full frame or APS-C shooters who already have the matching swab size
- Anyone troubleshooting a streak or smear after a wet clean
Not for
- Dry dust removal, which a blower or brush should handle first
- Sensors with visible grit that has not been removed, because wet cleaning can drag it
- Buying all three liquids before you know what is actually on the sensor
