There are lots of products out there for cleaning our stamps, like Wet Ones (other supermarket brands are available... lol) but I know a lot of people like me find that they leave tiny fibres on our stamps.
I have tried this, the Scrubber Pad from Hero Arts, along with ...
... their Ultra Clean fluid, but after a while I find the pad is so full of ink that I still need paper towels and a further spray of the fluid directly onto my stamp to fully clean it.
I know there are 'official' Stamp Shammy cloths available but I have found a cheap alternative in the UK that you might be interested in.
This is a car chamois cloth from Poundland (UK), so costs £1.00. It's about 14" x 11" and I cut it into 4 pieces, each about 7" x 5.5" (so 25p per cloth!!!!!!). I ran one bit under the tap to dampen it and now keep it on my craft desk in a little box to stop it drying out.
If it does dry out then it goes hard but that's no problem, run it under the tap again to soften it, I just keep it in a box so it's always available.
It cleans my stamps perfectly, first time, every time. The ink doesn't gunk up the cloth, it just absorbs it...no inky fingers, no inky build up and no fibres stuck to my stamps.
Here's the piece I'm using at the mo', as mucky as it is, none of the ink transfers onto my fingers and it still cleans my stamps.
I also tried this cloth from Wilkinsons (UK), another synthetic chamois cloth. It measures approx' 15" x 13", so can be cut into about 6 pieces and at £1.25, this is another bargain buy. It needs rinsing through before using as it has a 'soapy' feel to it, but just run it under the tap first and you're good to go.
Both cloths are brilliant for cleaning stamps.
I hope you find this useful.
