Jeyes 2231596 is an affordable and handy product. You can easily take the small, 1-litre can with you when necessary.

Sure, even diluted with water, the product won't let you make more than 5 litres of cleaning solution, meaning you won't be able to cover more than ~50 square metres. You can always purchase multiple cans though, especially considering how inexpensive these cans are.

On the bright side, the barely noticeable yet, at the same time, pleasant smell will let you use the product indoors, even where you cannot achieve/provide any airflow.

Of course, the product can be used to disinfect and clean various patios, paths, driveways, greenhouses, even plant pots and tools/instruments. You'll also be able to deodorise and clean outdoor drains and freshen water butts.

The product's potent formula kills avian influenza, bird flu, paramyxovirus, and even Newcastle disease virus. In other words, you can use this product to disinfect and clean animal houses, including kennels, hutches, coops, pigeons’ lofts, and stables. The formula even neutralises odours.

All things considered, Jeyes 2231596 is easily the most versatile product within this lineup. The solution will let you keep pretty much everything inside and outside clean and bacteria/virus-free.

Algon Organic Path & Patio Cleaner is pretty basic. We've no issues with the product's somewhat basic formula though.

Of course, acetic acid, the product's main active ingredient, makes the formula somewhat acidic, so we wouldn't recommend using this liquid solution around children and pets.

Other than that, the formula's 100% organic, so you shouldn't have any health/safety concerns. As long as you let the solution dry, you won't have to worry about kids, pets, even wildlife.

You can dilute the 2.5-litre bottle's contents with water, creating 10 litres worth of cleaning solution. That should be enough to cover ~60-70 square metres. You won't have to rinse the solution. You won't have to scrub it. Apply the product and walk away, its formula will do the rest.

We don't necessarily care for the product's smell though. It is strong and vinegary, which isn't something we like these cleaners to smell like.

We do, however, like the bottle. Its handle is large and grippy. The cap is easy to remove and easy to put back on. Plus, the bright neon plastic makes the bottle easy to recognise.

To sum everything up, Algon Organic Path & Patio Cleaner does the job and that's enough considering how affordable this organic patio cleaner is. Moreover, the results will last for 9+ months.
