Tarmac attracts algae, moss, mould and lichen – which needs to be periodically cleaned by soft washing.
In our experience the most effective soft wash product for treating tarmac is usually Benz Bio Cleanze.
Apply at 30-50:1, well brushed in. Then follow up with regular treatments at 50:1 (40:1 in cold weather) every 12-18 months (depending on the local environment and other variable factors).
We've found that when treating tarmac with Bio Cleanze, the dilution for a specific job can vary from 30-50:1. A stronger dilution can be used but tarmac is quite "thirsty", which means that treatment becomes more expensive the higher the dilution.
The actual dilution used depends on:
a) The external temperature. The colder it is the longer Bio Cleanze will take to work, which can be offset by using a stronger dilution.
b) The amount of moss or other biological growth.
c) How long moss has been allowed to grow into the tarmac.
d) Will children or animals will use the tarmac? If so, apply Bio Cleanze at a maximum dilution of 50:1 and keep them away from the surface until it is completely dry.
Quick tip: Contact your customer at the 12-18 month mark to offer them a quick re-treatment. This will give you a steady stream of repeat business.
The selling point for regular soft washing treatments with Bio Cleanze is that your customer will enjoy a tarmac surface that is permanently clean. This is a similar principle to regularly cleaning windows so they are always clean, rather than waiting until they are filthy, which most people really appreciate.

Yes, Lightning Cleanze will kill the growths very quickly. Lightning Cleanze is the soft washing product of choice when your customer wants immediate results and does not want to wait for Bio Cleanze to work.
If your customer just wants a quick clean before putting their property on the market, for example, Lightning Cleanze may be the most effective choice of soft washing product.
The downside is that the biological growths on the tarmac can turn into a white mush that many customers don't like.
Fortunately, giving a light power wash will usually to clear the mush. Be careful not to wash the rinse water into flower beds, lawns or surface drains (only foul water drains and if not available suck up and remove from the site). You will of course need to factor in the extra cost of power washing into your quote.
Bio Cleanze will clean the tarmac giving the appearance of lightening the tarmac.
In our experience, Bio Cleanze leaves the tarmac pretty much in it's original colour. So when the surface is cleaned from whatever colonisation was present, it looks lighter than areas that have not been cleaned but the actual colour is unlikely to have changed much, if at all.
Lightning Cleanze however, will impart an actual lightening effect to the tarmac. This is why we suggest applying it at 10:1 dilution and whenever possible treating tarmac with Bio Cleanze as your first choice.
Quick tip: If Lightning Cleanze is applied at dilution stronger than 10:1 the tarmac is much more likely to turn a light grey colour.
Some customers like this change of colour. Others do not. So always treat a small test patch at first and get your customer's agreement that they are happy with the results and give their agreement for you to clean the rest of the tarmac.
Our experience is that using Lightning Cleanze at 10:1 is the optimum choice for soft washing tarmac if your customer does not want to wait for the results of Bio Cleanze to show.

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus, moss and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
