How to remove skid marks from fabric What is an effective yet safe way to remove skid marks from fabric originating from keeping a bicycle on it?-- The back tire of my bicycle has been standing on a piece of rug and I need to clean the rug now (I didn't know I should have kept the rug clean until it was too late):
In a similar situation - bike tire marks, trainer residue and grease spots on the carpet - we found that scrubbing the carpet using a concentrated dish detergent (like Dawn, etc) worked very well.
