How to Clean a Red Brick Patio

By Corey M. Mackenzie ; Updated September 21, 2017

Brick patios are exposed to weather as well as to insects, birds and other wildlife. Naturally, brick patios become dirty quickly. There are many products for cleaning brick, some of which are caustic; in order to protect your flowers and lawn, an environmentally safe brick cleaner may be more suitable. In addition, these cleaners are generally much safer to handle--no protective equipment should be necessary (although you do want to avoid getting any in your eyes or on your skin).

Pull out any weeds or grass growing in between the bricks. Brush off all debris with a stiff-bristle push broom.

Wet the brick patio down with a water hose. You can put the water hose on high pressure to clean off much of the dirt.

Mix water and cleaner in a clean plastic bucket, according to product directions (for instance, if using Simple Green regular formula, you should mix one part of the product to 10 parts water).

Wet a mop in the cleaning solution. Use the mop to scrub the patio. For extra dirty or stained areas, scrub with the stiff-bristle broom.

Rinse the bricks well with a garden hose.


Things You Will Need

  • Stiff-bristle push broom
  • Garden hose
  • Environmentally safe cleaner
  • Bucket
  • Mop


  • Wait until the bricks are dry before replacing lawn furniture, plant pots or other items on the patio; moisture trapped between the bricks and other items can cause areas of mildew. If your patio has a lot of moss growing on it, using a stiff-bristle broom to clean will be very time-consuming. In these cases, buy or rent a pressure washer.


  • Most brick cleaners labeled "green" will not harm plants or grass; however, read the label to make sure you don't need to cover these prior to cleaning.
