30 seconds spray and walk away vs wet and forget

You have probably seen adverts from companies claiming that they are selling some special formula for killing Moss and Algae.

The two biggest names in the industry being ‘Wet and Forget’ and ’30 Seconds’, that's probably how you ended up here! 

Both of these companies sell colorful bottles full of big promises but the truth is that these two products are completely different and the active formula in one is just as useful as the other. The main difference between wet and forget and spray and forget are the ingredients.

The active ingredient in wet and forget ingredients is called 'Alkyl Dimethyl Benzyl Ammonium Chloride' also commonly known as 'Benzalkonium Chloride'Benzalkonium Chloride belongs to the quaternary ammonium class of biocides and is used in most moss/algae Killers. Benzalkonium Chloride is highly effective at controlling unwanted organic growths as it acts to keep the organic growths from returning for an extended period of time.

The only downside is the time it takes to get the results the average homeowner is looking for. 

At the concentrations that companies like Wet and Forget sell their products at, it can take many months to kill moss, lichen, mold, algae, and fungi.

30 Seconds spray and walk away, on the other hand, contains Sodium Hypochlorite; a completely different active ingredient and far more well known.

Sodium Hypochlorite (the main ingredient in spray and walk away) works incredibly fast and provides the instant results that most homeowners want but the downside with this chemical is that there is nothing to keep the organic growth away and at higher concentrations should be handled with extreme care.
