Tents
Once you get home set up your tent up one last time and sponge it down with a sponge, warm water, and soap. Do this on the exterior of the tent. To remove any excess moisture use towels and dab it on the area and let it absorb the excess moisture. Once you have finish doing that on the exterior of the tent repeat that step. Once it is dry roll it up loosely and put it in a breathable sack such as a pillow case. If you would like to speed up the drying process you are more than welcome to use a fan.
Thermo Bottles
Start off by using warm/hot water and dishwashing detergent to remove food and drink residue. If the residue has dried up, fill the bottle with hot water and add a tablespoon of baking soda and allow it to do its job for a couple of hours. If your bottle start to smell it would be best to use this trick! Soak the bottle in hot water and add a few tablespoons of lemon juice or vinegar. For stainless steel and plastic bottles a brush may be necessary.
Ties
Believe it or not ties are pretty difficult to clean. They are so difficult that even dry cleaners have problems cleaning them as well. Many of them are sold in silk. And you know that silk stains very easily. Whatever you do, do not attempt to rub the stain off. Instead work from the outside of the stain towards the inside to prevent it from spreading into a bigger stain. It is harder to clean silk ties, so it is best to leave that job to a professional to reduce further damage. In order to remove wrinkles you should try using a hand held steamer.
