Has anyone used this in their home? Is it difficult to keep clean? Considering half panelling throughout downstairs to cut down on wallpapering entire walls and appreciate that painted panels can be wiped down but concered they might be dust magnets and really don't want to spend my life cleaning any more than I already do! We've had tongue n' groove in the bathroom before and the inner grooves tended to look grimy no matter how often I wiped down. Haven't used these sorts of panels before and they always look elegant in pictures but suspect the reality may be very different so am asking those who have it...would you do it again? If you have had it but chose full wallpaper next time when you decorated, can you tell me what swayed you? Thanks. Pics are for examples and I prefer the first one showing a hallway.
