LOL, OK not funny, but I have been there and done that.
Only my dirtiest oldest and ready for trash shirt is used for that chore.
When I drain my tractor it always pours onto the sub frame and and just goes everywhere in spite of any and all the tricks tried.
My best friend to date is the old turkey roasting pan as it gets most of the spills but no matter how careful I am I always end up with a dyed black shirt sleeve.
