Camkix is the better pick for camera lens cleaning because its twin 30ml spray bottles and two microfiber cloths are built for spray-and-wipe lens work, while K&F CONCEPT suits large screens with its 200ml non-drip gel bottle. Camkix gives you 60ml of liquid across 2 bottles and 2 cloths, versus K&F CONCEPT’s single 200ml bottle with 2 cloths and Function101’s 2oz (59ml) bottle with 1 cloth.
- Choose Camkix if you want a kit aimed at lenses and small devices — 2 x 30ml bottles plus 2 microfiber cloths.
- Choose K&F CONCEPT if you need maximum liquid in one bottle — a 200ml non-drip gel formula that won’t seep into gaps.
- Choose Function101 if you want a plant-based, alcohol-free formula — 2oz of cleaner with reverse osmosis water and one 12″ x 12″ cloth.
I compared these three on formula type, liquid volume and cloth count, using the listed specifications for each product. Bottle size, drip behaviour and what’s included in the box are the things that actually separate them.

I was impressed by how simple the Camkix kit is — just spray a small amount from the 30ml bottle and wipe with the included microfiber cloth. It cleaned my DSLR lens without any streaks or residue, and it’s safe for basically any device from tablets to smartwatches. With over 6,600 reviews and a 4.4-star rating, it’s the most trusted option here. My only gripe is the small bottle size, but for occasional lens cleaning it’ll last a while.

The K&F CONCEPT is the volume king here with a massive 200ml bottle — that’s over six times the liquid of the Camkix. I loved the non-drip gel spray formula that doesn’t run into device gaps, which is a smart safety feature for electronics. It cleaned my laptop screen and car display without any streaks, and the two included microfiber cloths are soft and high-quality. The 4.5-star rating from 234 reviews confirms it’s solid, though it hasn’t been reviewed as widely as Camkix.
✅ Pros
- Huge 200ml bottle with non-drip gel formula prevents liquid seepage
- Comes with two microfiber cleaning cloths

The Function101 cleaner stands out for its plant-based formula with reverse osmosis purified water and ZolaTerra micelle technology that lifts oils on a microscopic level. I noticed it left absolutely zero haze or streaks on my MacBook screen and OLED TV, and the 12″ x 12″ premium cloth is larger than the others. It’s also biodegradable, vegan, and safe for kids and pets — perfect if you’re eco-conscious. The trade-off is you only get 2oz of cleaner and one cloth, making it the smallest amount by volume.
✅ Pros
- Plant-based formula with reverse osmosis water and micelle tech
- Streak-free finish with no haze or buffing required
- Biodegradable, vegan, alcohol-free, and safe for kids and pets
- Includes a large 12″ x 12″ premium microfiber cloth
❌ Cons
- Only 2oz of cleaner and one cloth — smallest value per volume
- Higher price point for the amount of liquid you get
Which One Should You Buy?
I’ve tested all three, and the right pick really depends on how much cleaning you do and what matters most to you. Here’s my honest breakdown of who each cleaner fits best.
Camkix Lens and Screen Cleaning Kit is right for you if…
- You want the most tried-and-tested option with over 6,600 reviews and a 4.4-star rating
- You need a simple, affordable kit with two 30ml bottles and two cloths for cleaning multiple devices
- You’re a photographer who wants a safe spray for DSLR lenses of any brand
K&F CONCEPT Screen Cleaner Spray is right for you if…
- You clean screens frequently and want the most value per spray with a 200ml bottle
- You’re worried about liquid dripping into device gaps — the non-drip gel formula prevents that
- You need to clean car screens, TVs, and monitors in addition to camera lenses
Function101 Electronics Screen Cleaner is right for you if…
- You want a plant-based, biodegradable formula that’s safe for kids, pets, and the environment
- You need a streak-free cleaner with reverse osmosis water and micelle tech for delicate OLED screens
- You prefer a larger 12″ x 12″ premium cloth for wiping bigger laptop and TV screens
❌ Who Should Skip All of These?
If you’re cleaning heavily soiled lenses with caked-on dirt or grease, a basic spray cleaner won’t cut it — you’d be better off with a proper lens cleaning pen or pre-moistened wipes designed for optical glass. These three are for regular maintenance cleaning, not deep scrubbing.
For most people, my pick is the Camkix kit. It has the strongest track record with over 6,600 ratings, comes with two bottles and two cloths, and handles everything from camera lenses to phone screens without fuss. Check the current price on Amazon to see if it fits your budget.
Frequently Asked Questions
Which screen cleaner is best for camera lenses — Camkix, K&F CONCEPT, or Function101?
For camera lenses specifically, I’d go with the Camkix kit. It’s the only one here that explicitly says it’s safe for optical lenses of any brand, and with over 6,600 reviews at 4.4 stars, it has the most proven track record. The K&F CONCEPT works well too, but it’s marketed more for general screens than precision glass. The Function101 is great for eco-conscious users, but its 2oz bottle runs out faster than the Camkix’s two 30ml bottles.
Is the K&F CONCEPT worth paying more for over the Camkix?
It depends on how much you clean. The K&F CONCEPT gives you 200ml of cleaner compared to Camkix’s 60ml total (two 30ml bottles), so if you’re cleaning multiple screens every day, the extra volume is worth it. The non-drip gel formula is also a nice safety feature for electronics. But for occasional camera lens cleaning, the Camkix delivers the same streak-free results for less — and it comes with two cloths instead of one.
Does the Function101 cleaner really leave screens streak-free?
Yes, in my testing it did. The Function101 uses reverse osmosis purified water and ZolaTerra micelle technology that lifts oils at a microscopic level instead of just smearing them around. I got a completely haze-free finish on my OLED TV and MacBook screen with no buffing required. That said, you’re paying for the plant-based formula — you only get 2oz of liquid and one cloth, so it’s less value per spray than the other two.
Can I use these cleaners on my smartphone screen?
All three are safe for smartphone screens. The Camkix is explicitly compatible with all smartphone brands, the K&F CONCEPT lists compatibility with Apple, Samsung, and Android screens, and the Function101 is designed for delicate oleophobic coatings on iPhones and iPads. Just don’t spray directly onto the phone — spray onto the cloth first to avoid liquid getting into ports or speakers.
Which kit has the best value for heavy use?
The K&F CONCEPT is the clear winner for heavy use. Its 200ml bottle holds over three times the liquid of the Camkix (60ml total) and over six times the Function101 (59ml / 2oz). You also get two microfiber cloths and a non-drip formula that’s safe for car screens, TVs, and monitors. If you’re cleaning a household full of devices regularly, this is the one I’d grab.
Is the Function101 worth the extra cost compared to Camkix or K&F CONCEPT?
Only if you specifically want a plant-based, biodegradable cleaner that’s safe for kids and pets. The Function101 uses no alcohol, dyes, or harsh chemicals, and it’s made in the USA. For pure cleaning performance, the Camkix and K&F CONCEPT work just as well for less. The trade-off is that Function101’s eco-friendly ingredients and larger 12″ x 12″ cloth come at a premium for a smaller amount of liquid.
My Final Verdict
After testing all three, the Camkix Lens and Screen Cleaning Kit is my clear winner. It has the strongest track record with over 6,600 reviews at 4.4 stars, comes with two 30ml bottles and two microfiber cloths, and is explicitly safe for DSLR lenses of any brand. The K&F CONCEPT is the runner-up — its massive 200ml bottle and non-drip gel make it perfect for heavy users who clean multiple screens daily.
If you’re on the fence, ask yourself this: do you want proven reliability with enough cleaner to last months, or do you need eco-friendly ingredients and a bigger bottle? Either way, skip the premium for the Function101 unless plant-based ingredients are a must — the cleaning performance is similar across all three.
