China Polished Surface 40*40mm 304L Precision Stainless Steel Hollow Square Pipes
What is precision steel pipe?
Precision pipe is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through
hot rolling or cold drawn (cold rolling) processes. So precision pipe is a kind of seamless pipe.
How do you get stainless steel back to shine?
Olive oil or any mineral oil can refurbish your stainless steel appliances to look as good as new. So grab some olive
oil from your pantry, and start buffing a small amount in the direction of the grain of the stainless steel. After this easy
hack, your kitchen appliances will shine like new.
How do you polish stainless steel to look like chrome?
Just spray the surface and then wipe it down with a paper towel or a lint-free towel. What is this? Once that's done
and the surface is completely dry, you want to put olive oil on a soft lint-free cloth and rub the oil into the appliance
going against the grain. Just keep buffing it until it shines.
