RiutBag+ stands up to household cleaners and disinfectants. I used house surface spray disinfectant, wipes and bleach on it. Reading the instructions to prepare, I realise that the bleach should be diluted to be used on anything other than a toilet or bath. However, I decided to test it with neat bleach too.
Both wipes and disinfectant sprays bring up a shine on the material, clean the surface and dry within 60 seconds.
Bleach is the harshest disinfectant I used. I tested it undiluted as well as well as at the recommended mix of 10litres to 50ml bleach. 1 hour of undiluted bleach on the RiutBag+ material did not harm or discolour the material. It was easy to wipe off with a wet cloth. However, if you leave undiluted bleach on it to dry, you will see where the bleach is. This dry bleach can then be wiped off easily too.
The RiutBag+ is designed for its surface to be cleaned daily, not to be machine washed annually, like other backpacks.
