Rubber Corrosion

Had an interesting experience with the rubber matting I have on the floor in the shed.  A week or so ago, I noticed a bit of an oil pool had gathered under where the SwordSaw was sitting on the edge of the table, and obviously the blade oil was slowly dripping down the blade and onto the floor.

Didn’t think anything of it (other than the mess itself that needed some cleaning up).

Noticed a pile of black,  insect-like flakes underfoot, and wondered where they had come from.  Looking closer, and I realised that it was the floor mat itself, slowly dissolving in front of me.  Guess the floor mat, sold for sheds etc is definitely not petrochemical resistant!!
