Difference Between Wet and Forget and Spray and Forget

Enzyme Concentrate cleaner 8oz

User often get confused when they come across the tug of war sort of situation between wet and forget v/s spray and forget.

Though for an instance it seems that both the products and companies are identical as both claim big regarding their effectiveness. But the truth remains, these products are way too different, both, in their compositions formula and the end-use. So what differs in both these identically named popular products is the ingredients of the compositions in making.

Wet and forget has a composition known as Benzalkonium Chloride, also known as Alkyl Dimethyl Benzyl Ammonium Chloride, A common moss/ algae killer biocide of the quaternary ammonium class family.

It’s quite accurate in killing harmful organic growth. According to Rasoop only drawback is, it takes a ton of time to finish the job, and as a homeowner, it can be a bit frustrating.

The concentration that the wet and forget companies use in their products are slow to kill mold, lichen, moss, and fungi.

Wet and Forget

Spray & Forget, on the other hand, uses sodium hypochlorite which is completely a different composition and is also widely popular due to its effectiveness.

Sodium hypochlorite which is commonly known as chlorine or bleach is a very common name when it comes to cleaning. It effectively eradicates fungi, moss, lichen and algae and that too at a rapid rate.

The spray and forget uses this formula and hence is faster in execution and end results. Which is very helpful to the homeowners. The con which it faces is that it cannot help in keeping the malicious organic growth away for good.

Wet & Forget VS 30 Seconds Cleaner

‘Wet & Forget’ and ’30 Seconds’ are probably the two most prominent names in the industry. Even the manufacturers claim that they are selling some special formula that can kill Algae and Moss.

Both these products are an active formula and basic chemicals that are quite similar to each other. Both these use a range of chemicals but the concentration and chemical type may vary product-wise.

For checking the concentrations of Wet & Forget and 30 Seconds you can go through the Material Safety Data Sheet.

If the product is for killing moss and algae then they are likely to use ‘Benzalkonium Chloride’. This belongs to the class of biocides which sits effectively for controlling the unwanted organic growths and doesn’t let it turn back for prolonged time periods.

One of the drawbacks as the results will be received over time, around 12-18 months.

Apart from this chemical, there is Sodium Hypochlorite which is another one that is used to kill algae, moss, and lichen. Many people use this active ingredient which is well known and is like bleach or chlorine used to treat things such as fungi, algae, lichen, moss, etc.

The other main chemical used for moss and algae treatment is Sodium Hypochlorite; a completely different active ingredient and far more well known among the homeowners. They are preferred as they give instant results and are incredibly fast. Though the higher bleach concentrations should be handled with care.

Comparing both is a bit hard in the real-world as one kills growth while the other keeps it away.
