The solution contains peroxide to remove grime and ensures that even the stickiest of oil stains is eliminated. It doesn’t matter if it’s grease, paint, exhaust the Simple Green Oxy can remove anything.

It can be easily applied as well. All you need to do is first wet the surface that you want to clean. Then apply the Oxy solve onto the surface at low pressure. Wait for 3 to 5 minutes and then start to clean at high pressure. You will be amazed at the results.

Buying Guide

Purchasing a cleaner seems quite a simple thing to do. And in fact, it is. That is, purchasing any cleaner is easy, but getting an effective item that truly gives you the results you need is pretty difficult to find.

Of course, cleaners are a sort of product that cannot be readily tested to determine their quality. It’s just a solution that contains several chemicals or ingredients that act as the cleaning agent. And it’s not easy to know about each ingredient.

However, you can still make sure that you get a satisfactory quality item depending upon your requirements.

Cleaners are specializing in removing different types of dirt. Some are good at removing grease, while some are good at removing algae. Also, some are better for cleaning patios and fences, while some are good for floors and driveways.

This guide will explain some of the important factors you need to consider to get the right cleaner. It’s mostly simple things like checking concentration levels, the convenience of applying the cleaner, and whether or not it is eco-friendly.

So, with this in mind, let’s see what you should know before going to the market.

Type of Cleaner

Several different cleaners exist for eliminating unwanted things from surfaces. For example, pH-neutral cleaners, acidic cleaners, alkaline cleaners, and cleaners use special enzymes.

pH-neutral cleaners are the most common type found on the market. In fact, in the list above, the majority of the cleaners are pH-neutral.

These cleaners usually need to be dissolved in water and applied gently onto the surface that needs to be cleaned. You can then rinse the surface with a pressure washer to clean.

Next, we have acidic cleaners. These types of cleaners contain acid and need to be applied directly to the surface. They are usually good for cleaning things that dissolve in acids. Contaminations that involve hard salts may be removed with acidic cleaners.

Then there are alkaline cleaners. These are again quite common and are mostly used to remove oil stains. Products mentioned on the list above contain such cleaners as well. These cleaners again need to be diluted in water before being applied to the surface.

But such cleaners take a lot of time to give the necessary results. In fact, if the stain is tough, you might need to do a lot of scrubbing to pry off the stains. So it’s better to use pH-neutral cleaners.

Lastly, enzymatic cleaners use special enzymes or bacterial organisms that literally eat away the compounds making up the stain. You don’t need to dilute these into water.

Directly apply to the surface and wait. Waiting, again, is the hard part with these cleaners. However, the good thing is that you don’t need to rinse or wash anything even after the cleaner has done its work. So it’s a bit more convenient than others.

Cleaning Agent

A cleaning agent implies the type of chemical being used to remove the stain. For instance, many cleaners use hydrogen peroxide to clean.

Hydrogen Peroxide is a widely known compound that is effective in removing harmful germs and dirt. The biggest advantage of using it is that it does not have any adverse effects on plant life.

Some cleaners use alkaline soap. They simply work by emulsifying fatty acids present in oil stains. Quite simply, oil or grease stains contain compounds that cannot mix with water. Cleaners containing soap break down these compounds so they can dissolve in water and be washed away.

So if you have a problem with oily stains, then perhaps a cleaner with such capabilities will be useful.

Sodium Hydroxide is another ingredient that is used in cleaners. It is more commonly known as caustic soda. The compound can break down the proteins found in contaminants. In fact, sodium hydroxide is the compound used in household soaps as well.

Perhaps, overall, hydrogen peroxide is the safest. Other acidic solutions may have certain harmful effects.


The next thing you need to consider when buying a cleaner is what type of surfaces you would be cleaning.

Of course, concrete is one of the many surfaces. But there are many things made out of concrete. If you want to clean up your driveway, then it’s best to get a concrete cleaner that can be used with a pressure washer.

After all, a cleaner that would require manual scrubbing would be the last thing you would want for cleaning your entire driveway.

Of course, you can get a cleaner that may not be compatible with pressure washers for interior flooring and other smaller areas.

These days, however, you can get a lot of choices. There are multi-purpose cleaners that can clean not only concrete but also wood, metal, and even plastic. So if you think you have more things to clean, then such cleaners might be the best.

Type of Contamination

If you follow this guide from the beginning, you would have realized that there are many types of contamination.

One is oil and grease. These are probably the hardest to remove. Next is moss and algae. Then comes dirt and waste materials.

Ensure that the cleaner you get can clean the type of contaminant you want to remove. Some cleaners may be good for removing common dirt but not moss and algae.

You will need to ask the seller or read the bottle’s label to see if it works on such things.


This is probably one of the most important things you need to be careful of when buying a cleaner.

In particular, if you are looking for a cleaner for the outdoors, then you will most probably have some form of plantations in the surrounding.

A cleaner that is not eco-friendly, or contains chemicals that may harm plant life, can create quite a mess even if it is good at cleaning concrete.

Acidic cleaners are perhaps the most dangerous in this matter. Usually, you will need to water the plants before applying acidic cleaners on the surface. This ensures the plants do not absorb the acid. But make sure the acid is not water soluble.


Sustainability is different from eco-friendliness in this context. Here, sustainability refers to the ability of the cleaner to have long-lasting effects.

It is of no use if, right after rinsing a surface with the cleaner, dirt and other waste build up again.

The cleaner should penetrate the surface to prevent any type of contamination from building up again.

This is especially true with concrete. Concrete has a porous structure so that dirt can sit in it for days. Cleaners should penetrate this and kill the source of the dirt altogether.


By now, you should have a pretty good idea of what you need to look for when getting a cleaner. As with everything else, you should be clear about your own needs.

Also, look for a good deal. That is, cleaners may come as 2-in-1s or 4-in-1s. In other words, you can get four bottles of a cleaner for one low price.

These deals really pull off the burden from your pocket. You also get enough quantity of the cleaner as well. So always lookout for discounts and offers.
