WD40 and duct tape r the two best tools which came along in recent years. No pro worth her/his salt would be without either.
I learned a long time ago that if you can't fix it with duct tape ... you are not using enough duct tape!
I have added another item to my list of best tools ... Velcro.

Maybe the dyslexia version of WD40?
Close but no seegar. DW40 is a commercial cleaning agent used in institutional kitchens in Poland. (Google is my friend.)

Did I say No enough? WD 40, incidentally, is noting more than fish oil with a penetrant. I am sure you do not want fish oil inside your lens.

"There is a popular email circulating that you may have seen. It states WD-40 is primarily fish oil, but that’s not true."

We got into this on a reel cleaning forum last week as well. WD-40 is a solvent first and a lubricant second. The main ingredient is mineral oil as a lubricant. Its main purpose is to loosen frozen parts. It does NOT contain fish oil, an urban myth. I use it to loosen components but I cannot think of one use on a piece of optical equipment.

My understanding is that the "WD" stands for "Water Displacement" and that the "40" is just that the 40th version did what they wanted.

might as well use crazy glue -both will ruin the lens.
