Many of us have patios that are made up of concreate slabs. The slabs may have been there for years and over time they can become discoloured. This can change the whole appearance of the patio area and even just after one winter you will notice the slabs start to dull. There are a number of ways in which you can improve the appearance of the patio without having to bring in the professionals. If you have got a jet wash or can borrow one, then this is the best way to clean them. Without the use of any chemicals, you can simply blast each slab to remove the dirt build up. This can take a little while to do as you will need to go over small areas on each slab individually.
If you do not have access to a jet wash then you may want to buy some patio cleaner and a hard bristle broom. Spray the cleaner on to the patio and then use the broom to scrub each slab. This will often not work as well as a jet wash but still can make a big difference to the overall look.
