Product FAQs

How long will it take for Path & Patio Cleaner to work?

This is dependent on the biological loading of moulds and algae. (How much biological growth and staining is on the surface)

For mild staining, you should see results in a couple of days, although heavier loads can take 2-3 months to see viable improvements, and in severe cases of contamination, it may take 6-12 months to work or to see the full results.

The reason for this, is part of the removal process is dependent on the weather cycles to remove dirt and biological contaminants from the surface. Once Path & Patio Cleaner has killed any biological growth it takes time for these to be weathered off the surface by mother nature.

The effects of subsequent applications or maintenance cycles will be seen quicker and usually within days.

When and how is it best to apply Path & Patio Cleaner?

It can be applied all year round, however results may be affected if rain occurs within 24 hrs and if temperatures are below 8 degrees Celsius.

Path & Patio Cleaner should be applied to a dry surface, and before applying any excess debris and bulky vegetative growth should be removed. Ideally it should be applied on a dry day with little or no wind. Whilst warmer weather will improve results applying on slightly cooler days with minimal evaporation, will allow the surface to remain wet for longer, giving the product time to work.

Is Path & Patio Cleaner safe around children and pets and will it damage plants?

Once dry Path & Patio Cleaner is safe around children and animals, however good practice is to keep them away during application.

If you need access to an area before it has dried, you can rinse it down with fresh water after an hour or more, although this can reduce the effectiveness, and it is best to let the product dry naturally.

Path & Patio Cleaner is plants safe provided you do not spray them directly. If you accidently overspray onto them, rinse down with clear water from a hose. It may scorch foliage, but it should not kill plants and grass lawns recover very quickly. It is good practice to protect them with waterproof fabric covers or plastic prior to spray.

On what surfaces can I use Path & Patio Cleaner, and will it cause any damage?

Path & Patio Cleaner is bleach, ammonia, acids, and solvents free. The product will not interact with any substrate or product that is not living and, unlike most other cleaners is non-oxidising so will not damage your outdoor surfaces.

It can be used on virtually any outdoor surface including tarmac, bricks and paving, concrete, decking, roof tiles, render, solar panels, Astroturf, artificial grass, canvas tents, caravans, conservatories, fibreglass boats, polytunnels, limestone, sandstone, marble, outdoor furniture, outdoor pots, outdoor painted surfaces, pool surrounds, slate, non-grass tennis courts, yacht sails. It can also be used to clean painted surfaces without the risk of damaging the paint film.

Can be used on decking, shed, fences, window frames and wooden garden furniture, it will prevent wood rot and disinfect as well.

Path & Patio Cleaner is excellent for pathways and patios, if applied regularly it can help prevent your path becoming a slip hazard, as it will prevent bio films (slime) from building up on the surface, which is one of the main reason decking becomes slippery.

Can I paint or stain over surfaces treated Path & Patio Cleaner and how soon ?

Yes. Once clean and dry you can paint over treated surfaces.

However, depending on contamination, you may want to leave the dead bacterial growth to start decomposing for 2-3 weeks prior to painting (or staining). You can then wash the surface and the dirt and residue will be easily removed.

As a natural surfactant Path & Patio Cleaner will help remove dirt & grime that causes fading as well as keeping surfaces free of moss, mould, and algae. If used annually it can help extend the maintenance or painting cycle.
