FIX sticky rubber on Gillette Mach3 handle

The rubber grip on the Gillette Mach3 razor handle will become sticky after sometime. This post will be about fully fixing/ repairing this. Initially I tried to scrap off the thick rubber, creating a big sticky mess (it won't come off easily). While doing that, I noticed that the rubber is are actually made up of hard plastic parts (coated with thick rubber), snap-fitted into the metal body. This suggest that the thick rubber parts can be cleanly and fully removed.

Tools I need:
  • A pair of scissors with a small sharp tip.
  • Pair of safety glasses (always good to wear one when fixing anything because lab-grown human eyeballs are currently not mass-consumer products).
The handle is made up of the rubber grip and the metal body. The rubber has become soft and sticky. See image below:

Look for an opening between the sticky rubber grip part and the metal body. Insert the tip of the scissors into the opening. The carefully/ slowly pry them apart.

For the smaller parts, each has 3 “snap-fit joints”. Use the scissor tip to push 1 joint upwards.

Use the scissor tip to push the other 2 “snap-fit joints” out sideways. Then remove 3 the rubber parts.

All 4 parts of the sticky rubber grip have been removed. Look at the amount of dirt in there, maybe this product can be made more hygienic if the whole handle is just 1 single piece of metal.
All sticky rubber parts cleanly and fully removed from Gillette Mach3 handle.

Scrub the metal handle with soap, dry it before use.

I find the metal handle by itself is sufficient for me to get a good grip. Sticky rubber handle fixed.

BUY cheap disposable foam earplugs


If you often use disposable foam earplugs (good for studying, sleeping), getting them from the local pharmacy can be costly. I chanced upon this bargain deal.

Of the various disposable (sorry mother nature) foam earplugs I purchased, this is one of the most value-for-money: Jackson H-10. One box of 200 pairs at $37.45. One pair can last me up to a whole week and one box up to a couple of years and ears :)

Alternatively (e.g. Jackson H-10 ran out-of-stock), get the Elvex uni-fit EP101, 200 pairs at $34.24.

The company I purchased from is PSE Safety Corporation Pte Ltd. Their customers are mainly businesses rather than individuals, but I have been buying a box from them every couple of years. They also have nice looking plastic safety glasses that looks like Oakley sunglasses, for around $10, which I also bought a couple.

Do avoid their lunch hour (I think it was 12pm to 1pm) and browse their website for the safety glasses' code number if you intend to get them. Some glasses listed on the website might be outdated (not sold anymore).
