Before leaving:take the tent out of its cover, wash it and clean the mold
The most important step before you go camping is to take your tent out of its cover and pitch it. Whether in your garden, or even in a public garden, this is the best way to ensure its overall condition, from the canvas to the number of pegs, poles and guy ropes. You will be able to take the opportunity to look at its assembly and disassembly by watching the dedicated video. It would be a shame to deprive yourself of this help, especially as you may not have internet connection at your campsite.
If your tent was stored a little damp, it might not smell very nice. You will therefore need to open the tent, air it, wash it with soapy water and leave it to dry.
If it shows marks of mold, you can clean it with soapy water.
