*Do not put Tightvacs in the dishwasher:  *HAND WASH ONLY* ---
Always thoroughly dry your Tightvac immediately. This will prevent the clouding effect that a lot of soaps and chemicals have on clear plastic.

*Keep the Interior of the cap & the top of the container clean.
This is very important – *neglecting the cleaning where the cap and body meet may cause the cap to become difficult to put on & off.

*Also storing sticky products may cause this effect as well. If this does occur - clean these areas thoroughly with alcohol or a strong soap. Make sure you have wiped clean all surfaces and then have dried them properly. There are now several methods to make your Tightvac work properly:

*We recommend WAX. Food grade wax – Candle wax – Wax paper – You can even use car wax if you are not eating out of the container. Simply apply wax to the inside of the cap & the body of the container where the cap & body meet. Let the wax dry, and then thoroughly rub wax off with a clean cloth until you have a smooth slick surface. Now you can put the cap back on your Tightvac -- This should make it alot easier to open & close your container. If your Tightvac has been neglected.

This is completely normal when your container is new. In the past Tightvac caps were made very tight - Since the conception of the Tightvac we have done extensive testing on how to make the Vacs last longer in the your home,office,business, kitchen or traveling. Making the caps slightly looser can double the containers shelf life! The more you open and close a Tightvac the tighter the seal becomes - Thus making Tightvacs the worlds - first truly Sustainable container.

The new Tintvac line - Colbalt - Rose & Emerald are made from a different plastic material and are more slippery then the clear and solid models. The Tintvac caps - when new appear to slide off easier. This is normal and after a few weeks of use will become harder to pull off without pressing the button. This material has the ability to last for 5 years and beyond - when properly maintained.

!!!ALWAYS KEEP THE AREA WHERE THE CAP & BODY MEET - CLEAN!!!

TRY THIS FIRST - Before following the Instructions below – Please clean your container with alcohol or the purest chemical free cleaner you can find – After cleaning try putting wax (wax paper, candle wax – Even car wax) around the areas where the cap and the body meet. If the cap does not slide up and down to your satisfaction – Follow steps below……
  
First you need to get Wet/Dry Sandpaper (used to be called Emery paper).
I believe this is Norton’s brand but other companies have it as well. Buy the 320 extra fine & 600 Ultra fine grain ratings paper.

Once you have this in your work area - take caps off completely (usually the inside of the cap isn't the problem – it’s the body of the container where the cap slides on - On the 1.3 Tightvac this is a 1" surface that is indented separating it from the main body of the container - thus making it easy to sand.

Start with the 320 extra fine and start sanding around the entire circumference of the container. I recommend spending at least 5 minutes carefully sanding this area - making sure to do it carefully so the sand paper doesn't accidentally scratch the main body of the container.

When phase 1 is completed then finish the job with the 600 Ultra fine by sanding carefully around the 1" area for about 2 to 3 minutes.

When this is finished, clean the container with a damp rag &  let dry - then use wax paper, candle wax or even car wax (If you are not eating out of the container) or any wax you may have on the sanded area and Bob's your uncle.

This should solve the problem.

The more you sand the easier the cap is to slide on & off. It is important to make sure the inside of the cap is clean and apply wax to this area as well. In some cases the inside of the cap may need sanding as well - in any case this will ensure your Tightvac to open & close until the whole container falls apart!!!

GOOD SANDING.
