They don't stand a chance against our all purpose cleaner, W99.
W99 is known for its ability to clean carbonized residue around exhaust pipes (check out this video from Auto Obsessed on how to do this), remove dirt and grease from engines, wheel wells and remove oil stains from concrete and carpeting.
But W99 also makes an excellent degreaser around the house and is very economical to boot!. Mix 1 oz with 16 oz of distilled water to make a grease fighting solution that you can use in the kitchen or on the barbecue grill to get rid of the most stubborn grease.
W99 is also great at removing the most stubborn soap scum (1:5-1:10) and unclogging drains (1:5).
