Will vinegar soften rubber?

As a general rule, wherever you find rubber, keep the vinegar away. The vinegar's acid can eat away at rubber just as it does natural stone. Soap and water or a solution of soap and baking soda are the best grime busters for rubber parts.

Silicone spray lubricant is suitable for metal, plastic, rubber, vinyl, wood, nylon and many other materials. Most quality silicone lubricants, including CRC 808 Silicone, are designed to respond well to extreme weather conditions, including extreme heat and freezing conditions.

Plumber's Grease vs WD-40

WD-40 is another popular greasing alternative for plumber's grease. Like silicone spray, it's easy to apply, and most people will have some lying around at home. If you're in a hurry and don't have time to get a plumber's grease, you can use WD-40 as a temporary alternative.

Seal It Up

To use Vaseline or petroleum jelly, gently clean the gasket with warm water and dish soap. Rinse and dry it, and then spread a thin layer of Vaseline over all visible parts of the gasket.

Rubber and lubricants need to come into contact with each other in many applications. But there are often problems with what is known as rubber "ageing": a deterioration of the properties of the rubber due to interactions between the rubber and the grease/base oils involved.

WD-40 can swell rubber or buna rubber gaskets when the gasket is immersed in the fluid. If the fluid is sprayed on and wiped off, the gasket will not swell. This swelling will not ruin the gasket, however it will swell the rubber.

A bent coat hanger works well. Heat up the rubber piece in a pot of boiling water. Pull the rubber out of the boiling water, then dip the cotton wad into some glycerine, and wipe down the rubber item with it. Let it dry for 24 hours, then heat the rubber again and wipe it down with more glycerine.

Canola oil provides a green alternative to items traditionally made with petroleum or its by-products. For example, canola oil is used in plasticizers that make the rubber in tires softer and more flexible, particularly in freezing weather. These tires better perform better on icy and snowy roads.

Plasticizers keep rubber in a pliable state for better utility. Silicone spray contains the plasticizers needed to restore hardened rubber to its original suppleness. You can also heat rubber to make it more flexible when cold temperatures have caused it to harden.

Baking soda is a gentle abrasive.

Combine 1/2 a cup (110 g) of baking soda with just enough dish soap to make a paste. Use a rag or soft brush to scrub the seal with it, then rinse it away with warm water when you're done. Don't forget to dry the seal with a clean towel when you're finished!

Just like with stone countertops, the acid in vinegar will strip away the protective sealant from stone tiles, making them look dull and leaving the surface vulnerable to etching and pitting.

The one time you should never use silicone lube is when you're using silicone sex toys. “Like damages like,” Dr. Rowen says. “Silicone lubes will break down sex toys." Instead, opt for a water-based with a silicone sex toy or oil-based if you don't need to use any latex barrier on the toy.

Silicone grease is commonly used for lubricating and preserving many types of rubber parts, such as O-rings, without swelling or softening the rubber, but is contraindicated for silicone rubber due to these factors. It functions well as a corrosion inhibitor and lubricant on non-metal-metal contact areas.

Silicone grease is NOT a petroleum product, it's a thickened silicone oil used not to pack, but to lubricate rubbers and synthetic rubbers. It is not used to 'pack' as the products it is designed to lubricate are the correct packing in themselves.

Silicone is the slipperiest of all lubricants, so it's a great choice for items that slide against one another. Silicone repels water, but not water vapor, so you can use it to dry out electrical connectors.

What lubricant is best for o rings? Silicone lubricant grease. Protective, waterproof, simple to use. As o rings are made from synthetic rubbers such as Neoprene, nitrile, and EPDM, you can use petroleum grease to perfectly lubricate the o ring.

To avoid damage to plastics as well as minimize ventilation issues, isopropyl (rubbing) alcohol can be used to remove petroleum jelly from most surfaces. Isopropyl alcohol is inert to most household surfaces, including almost every plastic, and removes petroleum jelly efficiently.

Gaskets prone to weather extremes, such as those on car doors, can age even more quickly if not properly maintained. Lubricating these gaskets with petroleum jelly or weather stripping lubricant will help prolong their lives, keeping them flexible and able to seal properly for years to come.

Tom: Motor oils, including synthetic ones, are based on mineral oils. The problem is that mineral oils and rubber don't mix well. The oils can cause rubber to swell or deform, and because there are lots of rubber seals in your brake system, that eventually can make your brakes stick, leak or even fail.

They help with the softening of rubber products and are essential in the production of polystyrene, PVC and different types of rubbers. This is critical for producing food packaging and utensils out of plastic. It can also be readily found in glues, cleaning products, polishes and plastic toys.

PHYSICAL TESTING OF RUBBER

This recognizes that the elastomer may be swollen or weakened to some extent by the oil. The tire rubbers (natural rubber, SBR), when placed in oil, absorb the fluid slowly until either the oil is all gone or the rubber has disintegrated. They never reach equilibrium.
