  • Saturate the stained area of your deck;
  • Allow it to set for a maximum of 10 to 15 minutes;
  • Proceed to rub off the stains using a stiff broom;
  • Use plenty of water to rinse your deck as the bleach will discolour and damage the wood in time.

Always use rubber gloves because this solution contains bleach that is harmful to your skin. The same applies to most dangerous household products too.

This is also a great DIY solution if you have a garden room that is made of wood. Scrub any mildew or mould stains off its veranda and walls using the concoction. If you want to clean a deck without pressure washer then use this method during spring cleaning to get it back in tip-top shape for the warm season.

Method #2 – Potassium salts of fatty acids.

They are also typically referred to as ‘soap salts’ and are used as fungicides, insecticides, algaecides, and herbicides. This makes them perfect to eradicate mould and mildew from any wooden deck.

Here are the steps you need to follow:

  • Clear all the furniture and plants off your deck;
  • Buy the ingredients for the potassium salt of fatty acids and prepare it as per the instructions you can see on the box. Please wear gloves at all times.
  • Use a mop to coat your deck with the solution in squares of 3-by-3 feet or 4-by-6 feet. The reason is that you have work while the wood is still wet;
  • Use a hard brush to scrub the portion of the deck where you applied the solution until you are satisfied with its cleanliness;
  • Repeat the same steps on another area of the deck until you’ve cleaned it all;
  • Use a hose to clean off all the soap and dirt off your deck once ready;
  • Coat it in the protective solution of your choice but only when dry.

How to clean a deck without a power washer by sanding and resealing it?

Here’s something you might not have known: Even people who opt to clean their deck with a power washer still have to sand it.

That’s because wood expands when wet and fibres rise up causing the floorboards to splinter. Without adequate sanding, the deck won’t be the same.

So you still have to do it, no matter what option you choose.

How to clean a concrete patio without a pressure washer?

If you thought we forgot about people with concrete decks and we were only going to focus on those with wooden patios, you couldn’t be more wrong.

First, let’s take a look at a general course of action. Here are the steps to clean concrete without pressure washer:

  • Start by removing furniture, plants, and everything else off your deck.
  • Sweep its surface very well to make sure there is no debris left.
  • You will also have to pull out any weeds that might have peeped out through the cracks in the concrete.

This is a great DIY solution based on bleach, fit for a concrete patio that has been lightly stained.

  • Mix bleach, water, and 1/8 cup of liquid dishwashing detergent;
  • Put the solution in a spraying bottle;
  • Spray the surface of your deck very well;
  • Allow it to sit for just a few minutes;
  • Scrub your deck with a brush that has nylon bristles. Remember that you need to wear gloves at all times as this solution has bleach in it;
  • Avoid using a metallic brush as it is not advised in this case. As you scrub, bits of it might fall off. In time, they will rust and leave ugly marks on the concrete deck;
  • Beware of spraying any flower beds or vegetable gardens;
  • Consider commercial oxygen bleach such as it is much safer;
  • Use a hose to rinse everything off once you’re done scrubbing;
  • Add a small amount of water to the oxygen bleach until it reaches a thick consistency similar to peanut butter. This works great for concrete decks with stains that won’t come out Apply on said stains and allow it to permeate for an hour;
  • Scrub again with your nylon brush.

Can I clean my garden furniture without a power washer?

It depends on the type of garden furniture you have, so let’s break it down into categories based on what material it’s made of.

  • Cane garden furniture
    Actually, the cane should never be left outside during winter because it’s not strong enough. So if you did this, just go ahead and buy a new one. We’re sorry!
  • Cast aluminium garden furniture
    Wipe everything with water and washing liquid. If you want to touch up the paint, rub off whatever has chipped away and then repaint it with an enamel metal paint. A good example is Hammerite.
  • Wrought and cast iron furniture
    Rub it with some wire wool. You can also repaint it if you want but you will need to coat it with an anti-rust primer first.
  • Resin furniture
    This will require detergent and a plastic brush. You can also use a very mild solution made with bleach if your furniture is white and you need to get it back to its original state.
  • Tubular metal furniture
    The plastic coating can be washed with the same solution made of detergent. Coat them with wax polish for extra protection and store them indoors.
  • Wood furniture
    If you have garden furniture made of hardwood such as mahogany, teak, oak or cedar, you won’t need to do much other than wipe them down with teak oil twice every year. This will preserve the wood’s original colour.

For upholstered furnishing, read our tips on cleaning sofa cushions.

However, furniture made of a softer wood such as beech, ash, elm, and pine needs some wood preservative as well as varnish.
