Use clean rags. Sounds easy. But often we re-use rags/cloths that we've simply washed and washed again. Fact is, rags wear out too, with the fibers leaving rough edges which not only can damage the area that you want to clean but also is not as effective as a good new cloth. The good news is that rags are fairly cheap when you shop carefully. Buying in bulk can save you a lot... and perhaps make your prized possessions look better for longer.
When polishing your furniture, remember to wash your dust rags after about two polishing sessions. That is to prevent damaging furniture surfaces.
You will be tempted to wash your kitchen sink with the same sponge scourer that you washed your dishes. Ideally, you should not, lest you leave scratches on the stainless steel surface of the sink.
Do not use the same rag that you use to wash your wheel rims or tires on the body of the car; there might be fine grains of sand or grit stuck to the cloth which could damage the duco.
