1, just use a brush, but if you can't use a wire brush, it will fall off, but don't scrape the tiles too hard. You'd better use some hot water to soften the glue before brushing your teeth.

2. Apply wind oil essence or cool oil on it, and then wipe it later, which is easy and environmentally friendly.

3. Drop 502 on the original place, melt the original glue, and then wash it off quickly with water.

4, with insulating oil, pour the insulating oil in the transformer on the table, the glue will soon become soft and can be wiped off quickly.
