Clean a Trampoline Mat

Cleaning a trampoline mat is easy, and can be done in about 30-60 minutes.

Steps

Using a large broom, sweep any loose debris off the mat. If there is snow on the mat, you may want to use a shovel, but cleaning a trampoline mat in winter is not exactly an ingenious idea.
Fill some buckets with lukewarm water, and add liquid soap until you have lots and lots of suds.
Pre-soak the mat with a hose.
Have your designated scrubber(s) get on the mat, and hand them buckets and scrub brushes.
Scrub away!
You can make it a race. For example, girls against boys, one half of the mat against the other, or timed to music.
Once everyone is done scrubbing, help everyone off the trampoline, and rinse it off again with the hose. Make sure you get all the soap off or the mat will dry sort of slimy and sticky.
Let the mat either dry in the sun, or dry it off with towels if you need the trampoline immediately after.

Spray some Pine Glo over your trampoline. Focus it mostly over dirty spots.
Make a washcloth all bubbly or sudsy.
Wipe off the Pine Glo with the washcloth and some water. Let it dry on its own.
- If you are in a hurry to get onto your trampoline, wipe with a towel.

Wear clothes that you don't mind getting wet or a bathing suit.
Make sure all the debris is of the mat. If not, you have a nasty mess.
Make sure that you have a water-proof trampoline bed.
If your trampoline still has marks that will not come off, spray on some carpet cleaner.
