How to Make Suction Cups Stick on a Stainless Steel Sink

A suction cup that doesn't adhere well is frustrating, if nothing else. The suction cup that sticks well to a window may not stick as well on stainless steel if the surface is slightly textured, such as on a brushed stainless steel sink. Petroleum jelly or cooking oil creates a seal beneath the suction cup, helping it stick even to stainless steel.

Both the steel and the suction cup must be completely clean to create a bond.

Step 1

Clean the suction cups by wiping them down with a damp sponge containing a small amount of dish soap. Rinse the suction cups under warm water while rubbing them with your fingers to remove any stubborn dust particles. Dry the suction cups with a lint-free cloth. Even small amounts of dust or dirt may render a suction cup completely ineffective and unable to stick.

Step 2

Sprinkle baking soda on a damp sponge. Wipe the stainless steel down thoroughly with the sponge, rubbing dirty areas to remove stuck-on debris. Rinse the sponge, and wipe the stainless steel again to remove baking soda residue. Dry the steel with a lint-free cloth.

Step 3

Press the suction cups onto the desired area of the sink. Tug down gently on the suction cups or the device they are attached to; if the cups slide or fall off, press them onto the steel again in another area -- a small dent or flaw in the steel may decrease the suction power.

Step 4

Wait several minutes and tug gently downward on the suction cups again. If they fall off or move, rub a thin layer petroleum jelly or cooking oil over the perimeter of the suction area of each suction cup using your finger or a paper towel. Press the suction cups into place again.
