How to Clean a Gazebo

As primarily outdoor structures, gazebos are faced with the challenges of the Great British weather more than most things. Blazing sunshine, pouring rain, and muddy environments. One of the most common questions we're asked by our customers, both before and after they purchase a tent from us, is how do I clean a gazebo? This is our quick guide to help you do just that.


How to keep a gazebo is the best condition

Firstly, pop up gazebos are not designed to be left out all year round. The covers are manufactured using UV protection, and are extremely water-resistant, so when you're using them you will be as protected as you possibly can be, and the unique concertina framework come in one piece and can be quickly deployed and dismantled in minutes, so to keep it in the best possible condition throughout the year, then we recommend that you take it down between uses.

When you take it down, ensure that the gazebo canopy is completely dry, to avoid the build-up of mildew and mould between uses. If you're at an event or show and want to get away quickly, then please ensure that you take your gazebo covers out of the storage bags and hang them up to dry properly.

Purchasing a gazebo storage bag for between uses is a good investment, and we supply bags for all of our frames. These bags come with added pockets, so you can keep your canopy away from potentially damp conditions.

However, we know that many users leave them up all year round, so, if you do have your gazebo erected all year round you would expect to clean this a few times depending on where this is erected. Whilst the covers are as protective as possible, there's always dirt and dust in the air, tree sap that can cause stains.

How to clean a gazebo

  1. Rinse off any visible dirt with clean, tepid water.

  2. For regular cleaning when there is no stains or grime, we recommend simple soapy water in a large bucket to build up a nice foam.

  3. You can use a specialist car cleaner or household cleaner such as washing liquid, both diluted in water work well.

  4. Do not use any strong acid, alkaline, bleaching or oxidising cleaning agents, as these may damage the surface of the gazebo covers.

  5. The soapy solution can be spread over the tent covers using a large sponge or mop, depending on the size of the gazebo.

  6. If there is stubborn dirt or grime, you may need to use a brush, or even a hard bristle deck scrubber for suborn stains or larger canopies

  7. We would NOT recommend using any electric scrubbing tools, if your pop up gazebo canopy is that far gone buy a new one.

  8. When cleaning be careful around stitched areas, contact with stitching must be avoided with aggressive cleaning which could destroy it and cause leakage. Careful manual cleaning is preferable where possible.

  9. Do not leave the soapy water on the gazebo covers for more than 5 minutes. Rinse thoroughly with clean water to ensure no soap residue remains. A hose or light pressure washer are effective for this job.

  10. The gazebo material must be completely dry before being packed away, otherwise mould and mildew could form and the material could perish. Wiping off excess moisture with a clean dry cloth or mop is advisable, as is hanging the gazebo tent covers on the washing line to dry off completely.

  11. You can also put back on the framework to dry off on a nice sunny day.

  12. Also, use the opportunity to wipe the gazebo frame clean too, then ensure this is also dry before packing away into storage.


How to clean mildew from a gazebo

After all, gazebos are exposed to dirty open outdoor environments and then spend most of their downtime being folded away and stored in environments like industrial units, garages and storage sheds.
