Use the cheap and cheerful No Nonsense sanitary sealant if after white or clear and Mapei if I need to colour match to tiles.
Straight cut nozzle, wet finger and masking tape if its a long run or has to be the dogs danglies!!
Would recommend baby wipes for cleaning up either yourself or accidents, find they work really well....no good using expensive ones though, cheapest ones in tesco or asda are the best for some reason.
