Cleaning Your Garden Furniture: Complete Care Guide

With the nice hot weather we've been having and still to come you may want to get the best use out of your garden furniture. Here are some tips for cleaning your garden furniture.

Wood

Wooden garden furniture can be so elegant and fitting to its natural surroundings, but it does require upkeep and some tender loving care in the form of cleaning to keep it looking its best. Most furniture made of wood can be cleaned by using the following top tips, with the exception of teak.

Basic Wood Cleaning

Clean wooden garden furniture using a warm solution of sugar soap and a scrubbing brush. For more stubborn areas, you can leave the solution on the furniture for a few minutes before shifting them with the scrubbing brush.

Professional Wood Cleaning Process:

  • Mix sugar soap with warm water
  • Apply solution to furniture surface
  • Let sit for 5-10 minutes for stubborn areas
  • Scrub with soft-bristled brush
  • Work in the direction of the wood grain
  • Rinse thoroughly with hose (not pressure washer)
  • Allow to dry completely

Rinsing and Drying

Then using your hosepipe (not pressure washer) rinse off and leave to dry.

Proper Drying Techniques:

  • Use gentle water pressure from hose
  • Avoid pressure washers that can damage wood
  • Allow furniture to air dry completely
  • Place in shaded area to prevent warping
  • Ensure proper ventilation during drying

Mildew and Mold Removal

If mildew is visible on your garden furniture, a top tip to cleaning your wooden garden furniture is to make a safe and effective solution made up by mixing 1 cup of any household bleach, 1 cup of washing powder and 1/2 bucket of warm water. Soak your furniture with the bleach solution and let it soak for 5 minutes (no longer). Then, simply hose off the solution and the mould, mildew or moss problem should disappear. Please take the necessary precautions when handling bleach solutions.

Mildew Treatment Process:

  • Mix 1 cup bleach, 1 cup washing powder, 1/2 bucket warm water
  • Apply solution to affected areas
  • Let soak for exactly 5 minutes (no longer)
  • Rinse thoroughly with hose
  • Allow to dry completely
  • Wear protective gloves and ensure ventilation

Oil and Sealant Guidelines

Try to avoid putting any oil or sealants on new oak furniture as oils tend to make the wood go black and pick up dirt, while other finishes just sit on the surface, change the texture of the wood and need frequent maintenance. The only exception to this rule is if the wood has been exposed to the elements for more than 10 years on average, the surface grain will have opened up and will need replenishing with oils.

Wood Treatment Guidelines:

  • Avoid oils on new oak furniture
  • Wait 10+ years before treating weathered wood
  • Use appropriate wood treatments for specific types
  • Test treatments on small areas first
  • Follow manufacturer's instructions carefully

Teak

By contrary, teak, is a popular alternative to some hard and softwood furniture due to its resistance to the outdoor elements. Teak tends not to require protective treatments that other wooden furniture may in the form of varnishes and oiling as teak is naturally resistant to the outdoor extremes. However, there is no getting away from dust and dirt, so it still requires some care!

Basic Teak Cleaning

To remove dirt and dust, hose it off with plain water - that is all that is required.

Simple Teak Maintenance:

  • Use plain water for regular cleaning
  • Hose down gently to remove surface dirt
  • Allow to dry naturally
  • Clean weekly or bi-weekly
  • No special treatments needed

Stubborn Dirt Removal

To remove stubborn dirt or bird droppings for example, use warm soapy water and a non-abrasive cloth or soft sponge.

Deep Teak Cleaning:

  • Use warm soapy water for stubborn stains
  • Apply with non-abrasive cloth or soft sponge
  • Gently scrub affected areas
  • Rinse thoroughly with clean water
  • Dry with soft cloth

Cleaning Frequency

Frequency of cleaning depends on the amount of dirt your teak garden furniture is exposed to, but washing it once a week or every two weeks is usually enough to keep it clean and look inviting.

Teak Maintenance Schedule:

  • Weekly cleaning for high-use areas
  • Bi-weekly cleaning for moderate use
  • Monthly deep cleaning for low-use areas
  • Adjust frequency based on weather conditions
  • Clean immediately after bird droppings

Teak Oil Warning

Please be aware that it is generally not a good idea to use teak oil if your garden furniture is made from grade A teak, because it destroys its natural protective oils. Once you start oiling teak garden furniture you must continue if you want it to remain suitable for outdoor use as most teak oils are made with solvents which replace natural teak oils that maintain the wood's resistance.

Teak Oil Guidelines:

  • Avoid teak oil on grade A teak
  • Oil destroys natural protective properties
  • Once started, must continue oiling
  • Use only for lower grade teak
  • Consider professional advice before treating

Metal

Oxidation, or rusting, tends to be the most common problem with aluminium or metal furniture. Try some of the below top tips for cleaning metal garden furniture:
