How to clean and store inflatables after hire

Why cleaning and storing your inflatable properly matters

After a fun-filled party, the last thing you want to think about is cleaning a bouncy castle. But taking a little time to clean and store your inflatable correctly will keep it in great condition for years. Whether you own an inflatable or you are returning one to a hire company, proper care prevents mould, tears, and pest damage. It also makes your next hire or party much easier. In this guide, we will walk you through the practical steps, from removing grass and mud to folding and storing your inflatable safely.

Step one: remove grass, mud, and debris

Before you do anything else, deflate the inflatable completely. Then lay it out flat on a clean surface, such as a patio or a large tarpaulin. Use a soft brush or a dry cloth to remove loose grass, leaves, and mud. Pay special attention to the seams and the base, where dirt tends to collect.

• Do not use a garden hose to blast mud off while the inflatable is still inflated – this can force water into the seams.
• For dried mud, let it harden, then brush it away gently. Avoid scraping with metal tools.
• Shake the inflatable gently to dislodge trapped grass. If possible, hang it over a washing line for a few minutes.

If the inflatable is very muddy, you can wipe it down with a damp cloth before moving on to the next step. Never use a pressure washer, as it can damage the material and stitching.

Step two: wash with mild soap and water

Once the loose debris is gone, fill a bucket with warm water and a small amount of mild washing-up liquid or a gentle soap. Avoid harsh chemicals, bleach, or solvents – they can weaken the PVC or nylon and strip away protective coatings.

• Dip a soft sponge or microfibre cloth into the soapy water and wipe down the entire surface. Work in sections, starting from the top and moving downwards.
• For stubborn stains, such as grass stains or sticky drink spills, use a soft brush and a little extra soap. Do not scrub aggressively.
• Rinse the sponge frequently and change the water when it becomes dirty.

After washing, wipe away all soap residue with a clean, damp cloth. Soap left on the surface can attract dirt and cause the material to become slippery, which is a safety risk for children.

Step three: dry thoroughly before folding

This is the most important step for preventing mould. Any moisture trapped in the folds will encourage mildew and bad smells, and it can rot the stitching. Do not rush this stage.

• Lay the inflatable flat in a shaded, well-ventilated area. Direct sunlight is fine for a short time, but prolonged exposure can fade colours and weaken the material.
• Use clean towels to blot away excess water. Then allow it to air dry completely. This may take several hours.
• If you are short on space, hang the inflatable over a washing line or a clean fence, but make sure it is not stretched too tightly.
• Turn the inflatable over halfway through drying to ensure both sides are bone dry.

To check if it is dry, press a paper towel against the seams and deep folds. If the paper feels even slightly damp, keep drying. Never store a damp inflatable, even for a day.

Step four: fold and store in a dry, rodent-free place

Once the inflatable is completely dry, fold it loosely. Avoid sharp creases, as these can become weak points over time. Fold in thirds lengthwise, then fold again, and roll rather than crease if you have the space.

• Store the inflatable in a breathable bag, such as a cotton sheet or a purpose-made storage bag. Avoid sealed plastic bags, which can trap moisture.
• Place it in a dry, rodent-free location. Garages, sheds, and lofts can work, but only if they are well-ventilated and free from damp. A plastic storage box with a lid is ideal, but make sure the inflatable is dry first.
• Keep the inflatable off concrete floors, which can wick moisture. Use a wooden pallet, a shelf, or a plastic sheet underneath.
• Rodents love to chew on inflatables, so check for signs of mice or rats. Use peppermint oil or humane traps if needed, but never place poison near the inflatable.
• Avoid storing near sharp objects, chemicals, or heavy items that could crush the material.
• If storing for a long time, add a few silica gel packets (in a breathable pouch) to absorb any residual moisture. Keep them away from children and pets.

Check the inflatable every few months. If you spot any mould, clean it immediately with a mild vinegar solution and dry thoroughly.

Extra tips for a smooth hire return and next party

If you hired the inflatable, check the company's return instructions. Some may ask you to clean it, whilst others prefer to do it themselves to avoid damage. Always follow their guidance. Before returning, do a quick inspection for tears, loose stitching, or missing parts. Report any damage honestly – it is better than a surprise charge.

For your next party, plan ahead. Store the inflatable clean and dry so it is ready to go. Keep a small repair kit with patches and glue for minor fixes. And remember, a well-cared-for inflatable is a safer inflatable, which means more fun for everyone.
