grabby mouse pad

(1/3) > >>

holt:
My mouse pad is getting older and grabby. What if I spray it with -say- silicon spray?

holt:
I'm not sure about it but it might be caused due to the dust beneath the mouse.
As for the mousepads, its layers peel off so there won't be any options for restoring them.

Thank you Swift Man. I found mention of safe food grade silicon, but I've reacted so badly to so much 'safe' stuff, I ordered a new pad; blue raindrops, my fav. :)

I suspect this mousepad (or maybe it's the mouse?) can't be fixed easily.
There's a similar problem I've noticed in some 15 year-old (or so) European cars like BMW or VW - which have always tended to use a lot of synthetic plastics (as opposed to say, ordinary rubber) on the outer coating of some rubber/plastic-coated controls/knobs in the passenger compartment. What seems to happen with them is that the outer coating (goodness knows what it is made of) of the control/knob starts to chemically break down. First it becomes slightly tacky to the touch, and then it becomes progressively more tacky to the point where some of the surface material sticks to your skin when you touch it, and it sort of spreads around. It can be removed from the fingers with white spirit, but if you try white spirit on the actual knob/control, then it seems to make the problem even worse for a while until the white spirit has evaporated and the whole substrate melts a bit and becomes gooey.
I've tried all sorts - e.g., including plastic/vinyl cleaner (is usually silicone-based), soap and water, hydrogen peroxide, salt solution, sodium bicarbonate (the main ingredient of baking soda) solution, white spirit, methylated spirit, isopropyl alcohol, gasoline (petroleum) - and they variously have either no effect or make matters worse. I have not yet found anything that sets the tacky surface hard(er)/less tacky.
The only solution so far is thus to replace the part, or (say) apply talcum powder to the the surface of the part. Yes, the latter is a kludge, but it reduces the tackiness and could be a useful temporary workaround - works on babies' bottoms too!  :Thmbsup:

Actually, thinking of babies' bottoms, I haven't tried paraffin oil on these knobs/controls, but that might make the surface smoother/slicker. On the other hand, paraffin (kerosine) is a petroleum product, so it might make it tackier. Either way, paraffinum liquidum (paraffin oil) is non-toxic/harmless (non-allergenic) - it's a tried-and-tested main ingredient in baby oil and is safe for use on babies bottoms (e.g., where there may be nappy rash) and is apparently a main ingredient in many commercially available skin cremes/oils and vaginal/anal lubricants also (it doesn't harm sensitive mucous membranes).
I hasten to add that my only experience with its use is as a generic baby oil and in the form of a herbal skin oil recommended by a doctor, and which bears the brand name Bio Oil:

I found this (and it looks like it is safer to replace than to attempt to restore): Conservation and restoration of plastic objects

holt:
I have tripped over my wired mouse cable - again. My foot-propelled laptop almost became airborne. No harm done this time, but I need a good wireless mouse with a new-type self-charging base. I have Windows 10 with an HP laptop that rests on the coffee table in front of me, but I like to lean back on the couch, and run the mouse back and forth on the couch cushion beside me where I sit. Do I have to always use a charging pad? Any suggestions up to about $35 would be most greatly appreciated.
