KEY POINTS

•

Our real-world test simulated heavy rain and nighttime driving — exposing which products truly work and which don’t.

•

Big-name repellents like Rain-X and Meguiar’s showed only short-term effects and even caused streaks or glare

•

DIY “life hacks” (like potatoes or vinegar) were messy, short-lived, and in some cases dangerous at night.

If you’ve ever driven through a storm at night, you know the feeling: wipers working overtime, streaks smearing across your windshield, and headlights from oncoming traffic turning everything into a dangerous blur.

The truth? Most so-called “rain repellents” simply don’t live up to their promises. They fade after a few days, leave behind a greasy film, or make visibility even worse once the wipers kick in. No wonder so many drivers feel disappointed.

That’s exactly why we decided to put the most popular windshield treatments to the test. We wanted to know:

Which products actually deliver crystal-clear vision in real driving conditions — and which ones fail when you need them most?

‍The results surprised us. Out of all the products we tested, only one stood out as a real game-changer…

6 Ways Probiotics Can Skyrocket Your Health

A recent study has shown a direct relationship between bad bacterial growth in the gut and the ability to fall and remain asleep. This can lead to sleep disorders that zap our energy during the day and create erratic sleep patterns. In short, the more good bacteria in our gut, the better our sleep!2

5 Things All Effective Probiotics Must Have

High CFU Count

Since our microbiome is composed of about 100 trillion good and bad bacteria, a high number of Colony Forming Units (CFUs) will have greater impact on the growth of beneficial bacteria within our gut.5 It's essential to choose a probiotic which specifies CFU versus "active cultures" or "live cultures." Look for a formula with a minimum of 40 billion CFU.

Prebiotics

The latest research shows that fiber-based prebiotics (such as NutraFlora Fiber) feed the probiotics, helping them to populate and flourish in our gut.6Choose probiotics supplements containing prebiotics to significantly increase the overall effectiveness of the probiotic.

Clinically Studied Strains

There are hundreds of different probiotics strains, but many have never been proven effective. The best way to identify the potency of a particular strain is to look at the clinical studies backing it up. To find out if a particular strain has clinical backing, search the strain name on the internet. Look for strains proven effective by clinical studies.

Formulated By A Doctor

It takes specific expertise to form an effective probiotic formulation. More is not necessarily better. The exact combination of strain type, potency, quantity, and prebiotics determines the product's quality. Look for real doctors specializing in gut health backing the product.

Proof of Results

Hundreds of brands make bold claims about their results, but the best probiotics for digestion are backed up by customer surveys. We've vetted all the top brands to see which ones have a proven track record of great results.

Every year, researchers make new strides in understanding probiotics and how they affect our health. We now understand that there are hundreds of unique probiotic strains that all perform different functions in our bodies. Some strains enhance digestion to minimize uncomfortable symptoms such as diarrhea and constipation. While others can enhance our mood, increase energy or give us greater mental clarity.

Here are some of the most effective strains available in a high-quality probiotic:

Top Probiotic Strains & Their Benefits:

While the potency and variety of strains is crucial when looking for in a high-quality probiotic, it's equally important to know what to avoid when looking for an effective probiotic.

The following 3 tips should help you sidestep those not worth your time:

Probiotics: 3 Things to Avoid

Limited Unique Strains

There are many different strains of probiotics and each one provides a different benefit. So it’s important to choose a supplement with a variety of “gut buddies.”
‍
While most probiotics feature only one or two strains — we recommend looking for a formula with at least 9 unique strains to boost your overall health and wellbeing.

Top 5 Probiotic Supplements Of 2023

1. ClearVision™ – Ultimate Clarity in Any Weather (Top Pick)

ClearVision

A+

OVERALL GRADE

PROS

Ultra-fast and effortless application (works in seconds)

Lasts for months — not just a few days like sprays

Crystal-clear vision in rain, storms, and night driving

Reduces dangerous glare from headlights

Over 20,000 drivers trust and recommend it

CONS

High demand — often sells out quickly

Only available online (not in stores)

The Bottom Line

ClearVision stood out as the clear winner in our test. Unlike short-lived sprays that smear or wear off after a few days, ClearVision bonds directly to the glass surface, creating a smooth, invisible shield. The result: rain beads up and rolls off instantly, glare from headlights is reduced, and your windshield stays clearer for longer.

It’s quick to apply, lasts for months, and makes driving in heavy rain or at night noticeably safer. For drivers who are tired of streaks, smears, and false promises, ClearVision is the only solution we found that truly works as advertised.

2. Rain-X Original Glass Treatment

by Rain-X

C-

OVERALL GRADE

PROS

Widely available and low cost

Easy to apply
(common “spray-on / wipe-off” method)

Has decent hydrophobic effect when freshly applied

CONS

Performance fades quickly — in our test the effect started to wear off within just a couple of days

Left behind a slight film that increased glare when driving at night

Caused streaking and occasional wiper chatter during rain

Requires meticulous glass prep — otherwise results are patchy and inconsistent

The Bottom Line

RainX may be one of the most recognizable brands on the market, but in our comparison it didn’t deliver lasting performance. While the initial water beading looked promising, the effect diminished rapidly and even created new issues like haze and glare under headlights. For drivers who want dependable clarity in heavy rain, RainX simply doesn’t hold up over time.

3. Meguiar’s
(Glass Cleaner + Water Repellent)

by Meguiar’s

D+

OVERALL GRADE

PROS

Recognized brand in car care

Simple one-step spray application (clean + repel)

CONS

In our test, the water beading was noticeably weaker than Rain-X

Faded extremely quickly — often gone after just a few rainy drives

Produced haze under headlight glare, reducing night visibility

More of a glass cleaner than a true long-lasting repellent

Not reliable for heavy storms or extended driving

The Bottom Line

Despite Meguiar’s strong reputation in car care, its water repellent spray performed poorly in our comparison. While easy to apply, the hydrophobic layer was weak from the start and wore off faster than Rain-X. In fact, it left more haze under headlights, making nighttime driving even more difficult. For serious rain protection, Meguiar’s was our lowest-ranked option.

4. DIY Home Remedy (Potatoes, Vinegar, Dish Soap)

F

OVERALL GRADE

PROS

Very cheap (ingredients already at home)

Quick to try in a pinch

Popular “life hack” often mentioned online

CONS

Extremely inconsistent — effect wears off within minutes or a single drive

Leaves streaks, greasy film, or even sticky residue on the glass

Makes glare and smearing worse under headlights

No proven safety or durability — not designed for automotive use

More hassle than help

The Bottom Line

We tested a few of the most common home remedies, such as rubbing a raw potato on the windshield or spraying diluted vinegar. While they may create a temporary hydrophobic effect, the results were poor and short-lived. In several cases, these methods left streaks and residue that actually reduced visibility, especially at night. For safe driving in heavy rain, home remedies are unreliable and potentially dangerous.
