Rated 5 out of 5 by from Bought this to clean my phone's internal circuit board, which had white residue, from minor water damage (the phone was still working). This worked perfectly. Removed the residue, no problem. Gave it a quick brush over. Let it dry. Now looks and works great. I like the smart straw on this, use it folded down and you get a large spray for big surfaces, fold it up and you can use the straw to get in smaller area's and be more precise. No more lost straws!

I have a synth from the 1980s and 90% of the keyboard no longer works. There are a number of rubber contacts for the keyboard and have heard that a contact cleaner will solve the problem by cleaning these rubber strips. Will this product work for this.

Asked by: steve99
The best way to clean those rubber contacts is to take the entire keyboard apart and remove the rubber contact membranes. Then clean the membranes with a gentle rinse in warm water and a little detergent followed by a rinse with clean water and a final rinse with RO water. (you can get RO water from most aquarium suppliers). If there is dirt residue on the circuit board, losen the dirt with a damp cloth and finally give it a wipe with a clean damp cloth with more RO water. RO (reverse Osmosis) or deionised water will be free from dissolved salts and leave no residue. It is also safe on plastics unlike many solvent based products. I have used this method on a number of synths with good results. There are some good video guides on disassembling keybeds on You Tube.

Can you use this on electrical equipment whilst it is running. e.g. Computer Tower whilst still on.

I am sorry but the item in question does not support use in your intended application.
