#理想家生活#推荐科技好物的话, this thing is usually inconspicuous, but it can save you a lot of money at critical moments! As long as you have a mobile phone, you can use it.

Some time ago, there was serious dust accumulation in the charging hole of the mobile phone, which caused the charging to always be in poor contact, and sometimes the charge would be disconnected.

So I searched and found this thing, precision instrument cleaner.

This is a chemical solvent of WD-40, but its insulation performance is very good, and there is no problem with EFI in the face of normal household appliances.

Its function is to clean the dust and oxides on the circuits of electronic products, so that the circuits look brand new and dry quickly.

I sprayed the charging hole of my phone, and the problem was solved after 5 seconds, and I sprayed the speaker hole again.

Later, I sprayed my switch watch and the cigarette lighter in the car.

Everyone can try electronic products with poor contact after a long time, and a bottle of about 40 on Taobao can be used for a long time.
