Stamp Quality and Care



The Quality of Kitchen Sink Stamps


Kitchen Sink Clear Stamps are made from a High-Quality Clear Photopolymer resign that won’t turn yellow (unless left out in the sunlight for long periods of time).

They have a deep etch, hold fine details and are not made from silicon like some stamps made overseas. 


This Photopolymer resign is porous which soaks up the ink for a crisp impression and works well with all types of inks*.

Staining from inks may occur, but this does not affect the quality of the stamp. 


Silicon stamps are not porous so the ink will sit on the stamp surface and bead up and therefore need conditioning. Our stamps need no conditioning before first use.


No need the cut Kitchen Sink Stamps apart, they are all ready for you to stamp and create. Just carefully peel the stamp off its protective acetate sheet, place on your acrylic block and start having some stamping fun!


Kitchen Sink Stamps are also 100% made in the USA.





An Important Safety message from the manufacturer of Kitchen Sink Stamps.


    “We continue to monitor and test products coming from overseas. It has come to our attention that many of the imported clear stamps contain phthalates. Phthalates are known to cause cancer, birth defects, and reproductive harm. 


The photopolymer clear stamps produced by California Clear Stamps [for Kitchen Sink Stamps] have NO harmful chemicals and are also latex free.”

How to Take Care of Your Kitchen Sink Stamps

Care for: Carefully peeling the stamp when removing from its protective film, will prevent tearing.  Keep stamps out of direct sunlight and long exposures to UV lighting (this includes fluorescent lights). Keep stamps out of high temperatures. Both of these factors can affect the quality of the stamps.


To clean: It is recommended that you use a stamp cleaner specifically made for cleaning and conditioning clear stamps. These cleaners work best when used together with a stamp scrubber pad. The stamp cleaner that is sold in the Kitchen Sink Store is made by same the manufacturer that produces Kitchen Sink Stamps.


Clear stamps may also be cleaned by wiping with a damp soft cloth or spraying with a clear stamp cleaner, letting the stamp sit a bit to loosen any dried ink and then rinsing under cool (not hot/not cold) running water*.    Soap is not recommended.  


Note:* I have also use a very soft baby toothbrush when rinsing under running water to get crusted ink off ... just don’t brush too hard! (this is not a recommendation from the manufacturer)


Stickiness: If your clear stamps lose some of their “stickiness” and are not sticking to their blocks the way they used to when new... all you need to do is wipe the back side of the stamp with good old fashion rubbing alcohol. Allow the alcohol to completely air dry. The stamp will now be as good as new. Natural oils from our fingers, ink residue can build up, leaving the stamps less “sticky”.  


To dry: clear stamps*, either air dry or pat dry with a soft cloth, but a cloth that won’t leave any lint behind on the stamp. Then the stamps should be returned to their protective storing place. 


*NOTE: When air drying, don’t leave cleaned stamps in brightly lit place. Photopolymer stamps are sensitive to UV light and long periods of exposure to UV light could cause damage.


Storing: There are a few ways to safely store clear stamps.


  Keep your clear stamps in between the 2 pieces of protective film from its original packaging.


  Some people store their clear stamps in DVD tins or CD jewel cases (out of direct sunlight is a good thing).



•  WARNING! Do NOT store your clear stamps where the stamp itself can touch any metal. The metal can cause a reaction in the photopolymer, causing the stamp to break down. 


Inks: Kitchen Sink Clear Stamps™ work well with all types of inks**. Staining from some types of inks may occur, but this does not affect the quality of the stamp. Because photopolymer stamps are porous, ink pigments can get embedded into the stamp, causing the stamp to “stain”.


Note:** If you choose to use an alcohol-based ink, like Staz-on, it is not recommended to use the Staz-on cleaner. It is possible that this cleaner may have a chemical reaction and damage the clear stamp.  (This is what I have heard.) When I use Staz-on, I just wipe it clean with a damp cloth or use a stamp cleaner made especially for clear stamps (the stamp will still be permanently stained).


Blocks: Even your acrylic stamping blocks need a good cleaning. Ink residue can build up and prevent the stamp from sticking. I would suggest wiping them with Windex or rubbing alcohol.
