Unlike heavy cotton canvas units, which shrink unevenly when wet, our lightweight poly canvas portable labyrinth mats may be washed.
When we used to clean our rental units (they inevitably acquired grime), we took them to a big do-it-yourself laundromat:
- Load in the largest capacity washer they have.
- Run Without Added Detergent on cold cycle.
- Get the extra or extended spin cycle if offered.
- Then load in the largest capacity dryer.
- Set on the lowest heat setting possible.
- It will take quite a while to dry. You will need to take it out periodically (each time you add more money for more time) and un-ball it to expose areas that are not getting air exposure.
Alternately you can wash your poly canvas labyrinth outdoors:
Clean a big slab of concrete and stretch out the cloth face up.
- Apply a very mild soap - not detergent, just a big squirt of dishwashing liquid thinned out in a bucket of water.
- Splash it onto the cloth from the bucket, then spread it all over with a garden hose.
- Scrub soiled patches gently with a brush.
- Don't let the cloth dry - keep it wet and after a few minutes rinse very thoroughly, starting from the uphill side of your concrete surface.
- Allow to dry in the sun.
Some stains simply will not come out, and you don't want to fade the ink forming the lines by over-cleaning. We call the accumulating evidence of use the labyrinth's "patina", which sounds much nicer!
