Will the Shoe Washing Bag turn my white shoes green?

No. The Koh Shoe Washing Bag is built with durable, colour-fast fabrics and is tested to TUV Level 4 colour fastness, so it will not turn light-coloured or white shoes green when used as directed. Wash on a gentle cycle at a maximum of 30 degrees, with no bleach and no fabric softener, and air-dry promptly.

✓ Colour fastness tested

The Shoe Washing Bag is built with durable, colour-fast fabrics and tested to TUV Level 4 colour fastness. It is safe for light-coloured shoes when you follow the washing instructions: gentle cycle, 30 degrees maximum, no bleach or softener, and air-dry promptly. See what the bag is made from for the full specs.

TUV Level 4 100+ wash cycles Safe for white shoes

✓ Keeping it that way

Gentle cycle, 30 degrees maximum. A lower temperature means less dye movement of any kind.

No bleach or softener. Both can affect dyes and finishes on the bag and on your shoes.

One pair per bag. Less rubbing means less risk of any transfer.

Mild detergent. Sensitive Laundry Liquid and Sensitive Laundry Sheets are both safe.

Air-dry promptly. Do not leave wet shoes sitting in the bag. The full washing method walks through it.

Should I rinse the Shoe Washing Bag before first use?

It is not required, but if you want extra reassurance you can run the empty bag wide open on a short gentle cycle before first use. That clears any residual lint or manufacturing dust so it does not end up on your shoes in the first wash.

✓ Optional new-bag rinse

Not required, but if you want extra reassurance before your first wash, run the empty bag wide open on a short gentle cycle. Leaving it unzipped lets any residual lint or manufacturing dust rinse out, so it does not transfer onto your shoes in the first wash.
