I tried to wash the exhaust filter but now it stinks while vacuuming. It's a kinda dampy smell.
Iíve just washed mine, first on a Handwash cycle (30ļ), then on a Cottons (20ļ).
Used the Astonish Stain Remover spray liberally on the first wash, along with detergent, but the cycle mustíve been a bit too gentle to agitate the material. Second wash was with more of both, only with both in drawer that time.
Still didnít result in a pristine clean filter, but itís certainly a lot better looking now.
I also added Whizz stuff in the softener section which, like the Dettol version, is designed to kill bacteria in the machine and clothes.
Itís on the line drying, so I canít tell you if I have the same damp smell coming from mineÖ maybe tomorrow, if I use it.
The point of this long preamble is to suggest that yours might have been damp smelling due to your machine not being as clean as imagined. If you tend to use fabric softener regularly, then it could be masking the odour.
I advocate not to use the stuff, as it causes a build-up of sludge that is a breeding ground for bacteria.
Assuming youíll be up for washing the replacement filter at some point, give the machine a good clean out and use the likes of that Whizz stuff. You should be able to get it from a local Home Bargains or the like.
Hopefully thatíll result in a clean smelling exhaust filter.
