I've used cat litter for small spills - i.e. the puddle left by GV51

At work we use cement powder - 25kg will cost about £4 from a builders merchant (like the one I work in)

If it is a thin film you could use detergent, couple of cheap bottles from your local cheap supermarket/pound shop.

Legally of course you must ensure not a drop reaches the drains!
